China’s largest telecommunications company plans to build a futuristic smart city in the suburbs of Shenzhen, in the near future, which will be free of road transport. During the construction of the “Net City” they will adhere to the principles and norms of “green architecture”, which will contribute to the preservation of the environment not only in this part of the metropolis. As the organizers of this ecologically safe area promise, it will not become an isolated island only for the elite.
Internet giant Tencent has revealed plans to build a new sustainable futuristic city in the Chinese metropolis of Shenzhen. Soon, a unique “smart” city will appear in the south of China, which will become a dream come true not only for the leaders of the country’s largest telecommunications company, but also for the majority of the world’s inhabitants. According to the concept that has appeared, the city will combine the latest achievements of high technologies, education, environmental safety, complete energy self-sufficiency and an ideally comfortable urban environment.
This event was preceded by a competition for the creation of the best innovative project of the city of the future, which will be able to leave a minimum carbon footprint and at the same time will be as comfortable as possible for people to live. In 2019, the American company NBBJ, known for its non-standard solutions, won the competition. As the project leaders admit:
“We spent a lot of time trying to make the city as less vulnerable as possible and move away from the use of road transport as much as possible, focusing on creating a comfortable life for citizens.”
“Net City” is the name given to the project, which will occupy an area of 2 sq. km at the mouth of the Pearl River, on lands that for many years were unsuitable for life or the development of agricultural land. Before the start of construction, large-scale reclamation measures will be carried out on this territory so that the allocated area is suitable for the construction and placement of the urban environment. According to the developers, the master plan gives priority to pedestrians with the most limited access to traditional types of vehicles.
Interesting fact: Despite the seeming diminutiveness, the area of the “smart” city will correspond to the size of the tiny state of Monaco. It is planned that at least 80 thousand people will be able to live in this paradise. And if we compare it with the same dwarf country, then in the “Net City” there will be 2 times more inhabitants.
Despite loud statements about the rejection of the use of vehicles, some areas of the city in the city will have transport arteries that will connect with the metropolis and allow you to move between distant points. Only for organizing the traffic of buses, bicycles and individual vehicles a single “green corridor” will be created around which the main residential areas, business center and recreation areas will be located.
The authors of the project report that most of the territory is given for the organization of parks, common recreation areas, but they plan to place numerous green areas on the roofs of buildings. Naturally, it will not do without the construction of a business center, educational institutions, residential areas, entertainment and recreation areas for citizens.
Despite the fact that the creation of this “smart” city was conceived as a place of work, residence and social interaction of employees of the conglomeration Tencent, the developers hope that it will become a vital hub for all of Shenzhen. Moreover, all the conditions have been created for the maximum integration of the new community into the urban environment of the metropolis. An unusual town, created on previously unsuitable for life and construction lands, will be connected to the main part of Shenzhen by road bridges, ferries and subway lines.
Given the changeable climate of the bay, the development team views the region as an organic ecosystem. Its clever design will transform it into a self-sufficient place to generate its own energy, recycle and reuse waste, produce its own food, and, ultimately, into a natural city-wide intelligent system with flexible interconnections. Such an ecological and innovative focus will have a beneficial effect not only on the preservation of the environment, but also significantly reduce the cost of maintaining all urban systems.
In this unique project, a special place was given to the embankment, which is a wavy green area in the form of a huge park. It is he who will be the connecting link between other areas of the metropolis and will become the central object of the city of the future. Along the entire length of the winding coast of the bay, tourists and locals can stroll and admire the opening views of the bay itself and the twinkling lights of the metropolis. At the same time, you can enjoy the fresh air and socializing.
Vacationers will especially appreciate the abundance of vegetation that can be observed throughout the entire length of this park and the entire city. Moreover, not only ground space will smell sweet, green roofs and vertical gardens on the walls of multi-level buildings will subtly fit into public spaces. And most importantly, the functions of the park space will be divided according to the goals of creating life, learning, interacting and working. At the southern tip, for example, are office buildings, to the east are commercial, entertainment and public spaces, and to the west and north are office properties mixed with residential high-rise buildings.
In general, the urban area promises to be ultra-modern and absolutely comfortable for people to live in.
“In today’s computerized world, we can build a city where work, life and play are closely intertwined and synergize with interactions between people.”– said Jonathan Ward, design partner at NBBJ.
Reference: Preparatory work for the creation of the future city will begin by the end of 2020, but the first residents will appear in it no earlier than in 7 years.
Freeman Dyson and his gigantic sphere
Science is always creativity. This is a search for new solutions and a game of imagination. Without all this, dry logic is useless. However, sometimes fantasy is capable of leading even the most brilliant, the most rigorous mind into unknown, cosmic distances.
Freeman Dyson is the famous scientist who came up with a truly fantastic scientific concept. This concept is known more than the creator, although it bears his name. This is one of the largest designs ever proposed by man. This is Dyson’s sphere.
Freeman John Dyson was born on December 15, 1923 in the small English town of Crowthorne (Berkshire). He was the second child of the famous composer George Dyson, who was knighted in 1941, and social worker Mildred.
The respectable family lived well, not needing money. Young Freeman showed a talent for mathematics and computing at an early age, and at the age of eight he was sent to boarding school in Twyford. There Freeman spent most of his time, appearing at home only on vacation. In fact, the boy was left to himself, but in those days this was the norm.
Unlike many outstanding scientists, Dyson did not experience any difficulties with his studies – the love of reading instilled in his mother affected. But the boy did not really get along with his peers. According to Dyson, the school was dominated by athletes who loved to rub everyone’s face with sandpaper. Therefore, he preferred to spend time alone, sitting somewhere in a tree and reading novels by Jules Verne and Frank Baum. But over time, he nevertheless made friends – the same children who were fond of fantastic stories and dreamed of bringing them to life. At the same time, Dyson decided to connect life with science, which since then has always been associated with him with freedom and friendship.
At the age of twelve, Dyson was lucky: his father was invited to teach music at the prestigious Winchester College, where he took his son. Paternal position, however, did not bring concessions to Freeman – he had to pass a difficult exam, which he passed with brilliance.
At Winchester, Dyson continued to study mathematics. He spent many hours in the extensive library, reading in the original French and German mathematical works, as well as the texts of Professor Vinogradov on the theory of numbers.
Fifteen-year-old Dyson met World War II with almost enthusiasm. The reason for this was youthful maximalism. “Hearing the sounds of explosions, I felt: this is the collapse of the British Empire of evil,” he said. In 1943, Dyson, barely out of college, went to work in the Royal Air Force. His job was specific – he figured out the most efficient and safest position of the pilots in the cockpits. True, all his works were in vain: the military almost did not use the results of his research, out of habit relying on outdated experience.
After the end of the war, Freeman worked at home for another two years. However, he doubted that he would be able to realize himself in depressed post-war England. And in 1947 Dyson moved to the USA – the country of Oppenheimer, Schrodinger and Einstein. In addition to the desire to participate in something truly progressive and large-scale, he, according to his sister, had another motive – Dyson longed to gain independence, to get out of the shadow of his famous father. Such adventures rarely end with something good … But exceptions do happen.
Dyson loved listening to the BBC’s coverage of life in the United States. And, surprising as it may seem, America really turned out to be as described: a country of extraordinary rise, including scientific.
Upon arrival, Freeman took a Ph.D. job at Cornell University. There he came under the patronage of Hans Bethe, one of the most famous physicists of the time. Bethe quickly realized that he had a non-trivial mind as his student. Soon Hans recommended that Freeman go to the annual summer school for physicists in Ann Arbor – a five-week celebration of science, where young scientists could listen to lectures by legendary physicists and even argue with them. There, Dyson met Richard Feynman, one of the creators of the American atomic bomb.
Feynman, who was only five years older than Dyson, was already a celebrity in the world of quantum electrodynamics. In 1948, he proposed the method of the so-called Feynman diagrams, which described the interaction of fermions (matter quanta) and bosons (field quanta) in space-time coordinates. The diagrams allowed the creation of a modern model of quantum physics. But one of the patriarchs of the then physics, Robert Oppenheimer, rejected the Feynman diagrams. But Dyson was confident in their correctness and in 1949 published a work in which he was able to mathematically substantiate Feynman’s calculations, which for the first time earned serious recognition.
In 1951, Dyson became professor of physics at Cornell. At the same time, the young scientist had not even received his doctorate at that time – an exceptional case. However, he taught there for only two years. In 1953, Robert Oppenheimer offered him a life appointment at the Institute for Advanced Study in Princeton – the place where Albert Einstein spent the last years of his life. Oppenheimer promised the young scientist complete freedom: he could pursue any field that interested him.
Dyson accepted the offer – and taught there until 1994, and after that he remained an honorary professor. During this time, he managed to work on the theory of resonant paramagnetic absorption of radiation by metals and on the theories of magnetism and the energy distribution of nuclei. He has published numerous works on cosmology, philosophy and futurology, received many prizes – the Nobel Prize, however, still bypassed the great scientist. And, of course, he managed to get a family – he lives with his second wife Imme to this day, he has 6 children and already 16 grandchildren.
In recent years, Dyson has been actively involved in the popularization of science. Several years ago, despite his considerable age, he traveled half the world with a series of lectures in which he expounded his thoughts on some of the problems facing humanity. He himself proudly calls his theses “heresies”, and himself – a heretic from science.
The first heresy is about long-suffering global warming. Dyson is not the first to argue that the scale of the problem is vastly overblown, as is the role of humanity in the “impending disaster.” However, he makes a reservation: of course, the warming will not pass without a trace for humanity. But it is much more important to solve, for example, the problems of overpopulation and poverty. And warming comes and goes – and the role of man in it is insignificant.
The second heresy is climate cycles. Dyson draws attention to the Sahara, which contains numerous artifacts from the past – and of sufficient quality. The Heretic recalls that 6,000 years ago the Sahara was humid – and in general the climate was completely different. In fact, the heresy lies in the fact that Dyson believes that the old, warmer and more humid climate is better than the current one.
To make the world hotter, Dyson calls for an increase in the concentration of carbon dioxide in the atmosphere – something that conservationists oppose. This would at least increase the size of potential agricultural land at the expense of the Sahara or Siberian tundra, which was a flourishing paradise.
The third heresy is the rise of bioengineering. Dyson argues that people are full of stereotypes about genetic engineering, similar to long-standing stereotypes about computers – they say, it’s all expensive, cumbersome, incomprehensible and only needed by a handful of scientists. But this will not always be the case, and people should be ready for this. The industry is moving forward by leaps and bounds. Freeman even predicts the creation of bio games – they will be similar to modern video games, only with real seeds. While playing, the child will select and see the growth of the plant in real time. Ultimately, genetic engineering can lead to a change in a person as such … but this is the next heresy.
The fourth heresy is about the essence of evolution and human biology. Dyson argues that humanity will soon return to the original evolutionary mechanisms of the “pre-Darwinian era.” Then there were no separate species and a kind of communism reigned at the cellular level – everyone exchanged data and did not differ from each other. But suddenly a certain cell stepped to a new level – and refused to share with others, forming the first species. So, according to the scientist, soon everything will change – humanity and all living things will again become one whole. And genetics and bioinformatics will help us with this.
Dyson draws an analogy with the computer industry. Like, once the industry was completely open until one company closed its sources. However, the very essence of software, according to the scientist, assumes open source. And something similar must happen with evolution.
The fifth heresy is about nuclear weapons. Dyson is a well-known pacifist and proponent of general disarmament. The scientist insists that nuclear (as well as biological) weapons only increase tensions in the world, and do not lead to deterrence, as popular belief says.
Many have a condescending attitude at best to these “heresies”. Dyson is already over ninety, his last serious accomplishments were half a century ago – well, grandfather is out of his mind, let’s be tolerant. The accumulation of carbon dioxide will help us – well, he gave it out!
But Dyson did not come up with all these ideas by accident. This is definitely not the case when a person is trying to cling to fame and once again get into the news feed. Dyson wrote about the advent of biotechnology and nuclear weapons in the 1980s – for example, in the books “Infinite in all directions” and “Weapons and Hope”.
He himself admits that he cannot call himself an expert in all areas. “I am not suggesting that these heretical ideas are true,” says Dyson himself. “But pondering them is not at all harmful.” This, perhaps, is the secret of his longevity – both physical and mental: Freeman is interested in literally everything, he approaches any topic so responsibly, as if he is going to devote his whole life to it.
Physicist Marvin Goldberger said that for Dyson there seemed to be no problem that he could not solve. Marvin once worked on an incredibly convoluted integral equation. Dyson passed by and, of course, became interested in the problem. He honestly admitted that he had never seen anything like it, but he made a decision within twenty minutes. Later, this solution was derived by other scientists – and the equation bears their name. Freeman never chased fame or recognition – he just solved interesting problems.
“I still cannot imagine how you can think with such speed and such mathematical clarity. Against him, everyone else seemed inhibited. You can’t learn that. At least I just can’t do that, ”Goldberger said.
One of the famous but unrealized projects that Dyson was involved in was a spacecraft that would be propelled by nuclear explosions. In the United States, work on Orion began after the Soviet satellite was launched. The first Orions were planned to be launched already in 1968 – but in the end, as you know, NASA chose a less complex and dangerous version of chemical-powered rockets. Freeman’s son, science historian George Dyson, wrote a whole book about the history of the project.
All in all, the scientist Dyson is undoubtedly outstanding. But there are many outstanding scientists, but there are few scientists who have come up with a real Idea with a capital letter. And here we come to the idea for which Dyson became famous. This is definitely Dyson’s domain.
Dyson got the idea for this design in the fantastic book by Olaf Stapledon “The Creator of the Stars”. In it, the author describes a journey across the universe, many different races, societies and organizations. Among other things, Stapledon mentions a giant structure located around the star.
Dyson was inspired by this image and in 1960 proposed the idea of such a sphere in his work “Search for artificial stellar sources of infrared radiation.” The scientist suggested that over time, the energy needs of any sufficiently developed civilization become so high that there is only one way to satisfy them. Namely, a colossal structure around the nearest star, which, with the help of batteries and photocells, could absorb and accumulate almost all the energy of the star.
Such a megastructure should become a noticeable source of infrared radiation that is fairly easy to detect. In the 1960s, there was much hope for the search for extraterrestrial life. The search for radio signals had already begun – Freeman proposed another method.
Dyson immediately said that his idea was hypothetical and in any case related to the distant future. He did not set the task of devising a way to build such a sphere. He, as always, was simply guided by the rule “thinking it over is not harmful at all.”
But many people immediately came up with a question: can humanity build such a sphere? And is it even possible to build it?
The radius of a hypothetical sphere around, for example, the Sun (far from the largest star) will be approximately equal to one astronomical unit (150 million kilometers). Not only the Sun would be inside the sphere, but also Mercury and Venus.
Of course, a lot of questions immediately arise. Where to get such a durable material? How long will it take to build?
And if you can answer the above with the vague “well, the technologies of the future, they will come up with something”, then other problems run into the laws of physics.
The main problem is gravity. Newton put an end to the idea of a monolithic construction by proving the hollow sphere theorem. According to her, within a symmetric shell, the forces of gravity are mutually exclusive, so the body is in weightlessness.
As a result, the sphere will begin to drift and may simply “run over” the star, which will result in a complete disaster. Of course, the structure can be supported, say, with the help of motors – but imagine how much energy is required for constant maneuvers! Another problem is temperature. On the surface of a sphere, it can reach hundreds of degrees Celsius – too much for comfort. The earth is cooled by the atmosphere and rotation, the sphere will have neither one nor the other. There are two ways out: either spend a colossal amount of energy on cooling, or expand the radius of the structure.
Another challenge is the material. In 2012, the head of the board of directors of the American Institute of Ethics and New Technologies (IEET), George Dvorsky, said that humanity could well build a sphere in the next fifty years. He proposed to blow up Mercury, and the resulting material, in fact, and put on the construction site of the century.
Dvorsky’s theses were predictably criticized. There are a lot of questions – from “how, in fact, humanity will explode Mercury” to “how will you transfer the energy received from the Sun to the Earth.”
Ring with a diameter of 1 au – the simplest form of the Dyson structure
But the main thing is that the mass of Mercury is simply not enough to build a sphere with a radius of 1 astronomical unit. According to some estimates, there will not be enough material in the entire solar system to build a stable structure – the shell will literally be a few centimeters thick. Some crazy asteroid, and …
To solve these problems, Dyson introduced new concepts. He described several megastructures at once (the initial idea was called the “Dyson shell”), in which there is nothing openly impossible or contrary to the laws of physics.
The Roy, or Dyson Cluster, is a system consisting of a huge number of independent satellites that tightly “stick around” the star, moving in orbit around it. The main difficulty lies in controlling the satellites – after all, you need to ensure that they do not collide, do not go out of orbit and keep a distance between themselves.
A Dyson bubble is very similar to a swarm – with one difference: if the swarm is in continuous motion, then the bubble, on the contrary, is static. In the Bubble concept, the star is surrounded by many giant solar sails that remain in place due to the influence of the solar wind. The problem with movement control disappears, but another appears – the satellites should be extremely light and at the same time large.
Bubbleworld (literally – a bubble world) is an unusual variation of a space colony, which is also built around a huge sphere filled with hydrogen (a gas giant is also suitable). Along its perimeter there is a vital shell heated by a ball – with soil, air and water.
Dyson’s network is a huge array of cables and wires stretched from planet to star with photocells that absorb and transmit the energy of the luminary.
Be that as it may, many researchers around the world are still looking for the Dyson sphere – for example, within the SETI (Search for Extraterrestrial Intelligence) project, aimed at finding alien civilizations.
In 2015, astronomers recorded the strange behavior of the star KIC 8462852 – its luminosity over different periods of time (from 5 to 80 days) fell by up to 22%, as if something was blocking it. One of the hypotheses explained the phenomenon by the presence of an artificial structure around the star, like a Dyson swarm. However, there are other versions as well.
The Dyson Tree is indeed a tree, but not quite ordinary. First, it must be created from scratch using bioengineering. Secondly, it will not grow in the forest at all. Such trees need to be planted on comets to create an atmosphere on them suitable for human life. Dyson believes that extraterrestrial life will first be discovered not on a planet or satellite, but on a comet or asteroid. And he even put $ 2,000 on it on longbets.org, a site created to make open-ended bets.
Undoubtedly the most famous piece to show Dyson’s influence is Larry Niven’s The Ringworld. Niven described a giant ring (millions of kilometers in radius) that revolves around a star to create gravity and is surrounded by a thousand-kilometer wall at the edges to contain the atmosphere. Over time, the idea of a ring-world took on a separate life, even eclipsing its progenitor.
Peter Hamilton’s Pandora’s Star begins with the discovery of objects similar to Dyson spheres. The sphere is mentioned in “The Rising of Endymion” by Dan Simmons, it is found in “Life Space” by Russian science fiction writer Andrey Livadny. The complete list includes several dozen pieces!
Perhaps the greatest science fiction writer who has dealt with this topic is Stanislav Lem. True, he did not introduce it into his books, but went through it with a roller of criticism. In the collection of essays “The Sum of Technology”, the Polish science fiction writer blows the sphere to smithereens, calling it “a curiosity rather than a concept.” His criticism is fair in everything but one. Lem writes: “Dyson is so convinced of the inevitability of the creation of” near-solar spheres “that he suggests starting a search for them in space …” But, as we know, Dyson was not convinced of anything – he only offered food for thought.
The Dyson sphere has taken root well in the gaming industry. You can stumble upon it in the Freelancer game. The main character of the game Prey is taken into the sphere. In Sid Meier’s classic strategy Alpha Centauri, building a sphere is considered one of the winning options. In the later stages, it can be built in the games of the Space Empires series. It is built by the geth from Mass Effect, and you can visit it in one of the storylines of the Russian strategy “Star Wolves: Civil War”. And in the wonderful game Euphloria (which was called Dyson in the early stages), you can grow a Dyson tree. In the cinema, Dyson was not lucky – neither the sphere nor his other concepts are practically found there. You can only recall the 1992 series of “Star Trek”. This, however, is understandable – a structure of this scale is too difficult to show realistically.
Frog in a jar
Dyson said: “There are bird scientists, and there are frog scientists. Birds soar high above the vast expanses of mathematics. Frogs swarm in the mud and see only flowers growing nearby. They enjoy looking at specific objects. “
Dyson’s cake opened on the scientist’s 90th birthday (Photo: Andrea Kane, Dan Komoda)
In this classification, Dyson refers to himself as a frog. This could be explained by the inherent modesty of the scientist, but this is not entirely true. Dyson never really explored something in its entirety – he took only a separate, interesting aspect for him, jumping like a frog from one problem to another. And he did not care at all that the project as a whole was impracticable, he did not bother with technical characteristics – for him, a pure idea was always in the first place. His contribution to quantum mechanics, random matrices and astrophysics is enormous – but he seems to have never realized himself to the maximum, preferring to discover more and more new facets of our world.
He has not achieved fame among the masses. The name “Freeman” is more associated with another physicist – a lover of cascade resonances from the Half-Life series. Few know Dyson – he is far from Stephen Hawking or Neil DeGrasse Tyson, he is hardly mentioned in the media. If you score “Dyson” in the search, you will be greeted by an advertisement for vacuum cleaners.
Even at an advanced age, Freeman Dyson does not lose interest in the world around him.
His most famous “invention” – the sphere – he never considered a subject of pride, emphasizing that this was not his idea. For many other scientists, it would even be humiliating – to be known about you only by a near-fantastic concept, which was not even invented by you!
But Freeman Dyson’s ideas inspired and inspire many science fiction writers, artists, game developers. His concepts make people think about something great and distant. Impossible. So, everything is going as it should.
Dark secrets of DNA. Scientists talk about dangerous types of marriage
Scientists sequenced the genome of a man buried in a Stone Age tomb at Newgrange in Ireland and found that he was born as a result of incest. Marriages between close relatives were almost always prohibited due to the threat of degeneration. However, there is a risk of accidental incest. How dangerous it is from the point of view of genetics?
Power sealed in blood
For biological and cultural reasons, incest has been taboo since ancient times. They violated the ban in exceptional cases for the sake of strengthening power. Probably, the discovery of Irish scientists in Newgrange is connected with this – with the formation of the ruling elite in prehistoric society.
Dynastic marriages between relatives and cousins were concluded in Ancient Egypt, the Inca empire, in the royal families of the Hawaiian archipelago. It once symbolized the purity of blood.
The majority of Iceland’s 360,000 inhabitants are descendants of several Viking groups who settled on the island in the 9th century.
The population is genetically very homogeneous. A few years ago, local company deCode Genetics even released an app based on a DNA test database to prevent young people from accidentally marrying a close relative.
DNA rushes to the rescue
Computer programs have been developed that compare a set of certain regions of the genome and determine the degree of relationship. Genealogical research is generally very popular now. People do DNA tests, upload the results to public databases such as Ancestry and Gedmach, and find relatives. First of all, those who do not know their origin: raised in orphanages, adopted.
Sometimes this kind of research brings unpleasant surprises. So, an American gave her husband a DNA test for his birthday. The results shocked the spouses: they turned out to be first-order cousins on the father’s side. Moreover, the couple already had a two-year-old child. The woman spoke about this a year ago in the podcast of the American publication Slate.
Scientists immediately warned that sperm donation is fraught with accidental incest, and recommended strictly limiting the number of children conceived by one donor. In 2011, The New York Times reported 150 half-brothers and sisters. In 2017, the British press raised the issue of countries like Nigeria where the legislative regulation of this area is weak. Last year in the United States, there was a lot of discussion about the story of Dr. Kline, who tricked female clients of a reproductive clinic with his own sperm. Nearly five dozen of his biological children have found each other through public DNA testing databases.
How dangerous are “dynastic ties”
Children of incestuous marriages are twice as likely to get hereditary pathology. They have a higher risk of rare genetic diseases (orphan diseases) caused by recessive alleles – variants of genes whose activity is usually suppressed.
“Both spouses can inherit a recessive mutant allele from a common ancestor. They are healthy, but they have a heterozygous genotype, that is, with this allele. The probability that such a couple will have a sick child with a homozygous genotype is 25 percent,”.
If both parents carry an X chromosome with a mutant gene, then the risk of passing them on to both children increases to 25%. This situation often develops in closely related marriages.
In this case, medical genetic counseling is necessary in order to reduce the risk of passing on the genetic pathology to the child. Experts take into account everything: the degree of kinship, the state of health of family members, other kinship marriages in previous generations, ethnicity, since some hereditary diseases accumulate in certain ethnic groups.
“During pregnancy, you can undergo prenatal genetic diagnostics in order to obtain the most accurate data on the genetic material of the child,”.
Meanwhile, according to various estimates, about a billion people live in closed communities, where closely related marriages are not uncommon and even encouraged. For example, in Egypt, men could only marry if they had a home. Accordingly, the problem was solved by marriage between relatives living under the same roof – as a rule, cousins.
“In southern India, more than 52 percent of marriages are between cousins and second cousins. Many nationalities have lived like this for thousands of years and have not disappeared from the face of the earth because of a rare recessive gene associated with any disease,”.
A person is able to adapt to almost any situation, Sosin believes. The most serious pathologies that are not compatible with life are eliminated even at the zygote stage – when the germ cells merge or the first few divisions of the embryo. If the pathology is not fatal, the child can be born.
Scientists give an example – Turkey, where marriages between cousins and sisters are very common. Infant mortality is high there, and among the elderly it is common in countries with similar income and social security levels. This phenomenon is called the “Turkish puzzle”.
“In 1968, 27 percent of marriages in Turkey were concluded by close relatives. In 2008, 24. Studies have shown that, in general, first-degree marriages, that is, between a cousin and a sister, increase infant mortality by 45 percent. This is another insurance policy. , through which nature removes from the equation of life children who are not able to exist physically fully, “.
However, it is incorrect to deduce a certain average value of the risk of pathologies in closely related marriages. Each case is unique. It is especially difficult with multifactorial diseases, the causes of which remain unclear. By the way, they can be ecological, rooted in the way of life. For example, schizophrenia. Parents with this diagnosis have a 29 percent risk of transmitting the pathology to their child, and 41 percent if they are close relatives. According to some reports, children born in a marriage between a cousin and a sister have slightly worse IQ scores (by 0.8-1.3 points).
On the Internet, they write that in closely related marriages, almost half of the children are with hereditary pathologies. In fact, Sosin emphasizes, much less. According to various estimates, from one to nine percent, when it comes to parents who are each other’s first generation cousins.
The mystery of Azzo Bassou, nicknamed the planet’s last Neanderthal
For years, scientists have been looking for the missing link in human evolution, the “connection” between humans and their ape-like ancestors, according to evolutionary theory.
Scientists ran to look at new evidence of the existence of the Yeti and the Bigfoot, just to catch this very connection. But there was one person in the history of science who excited scientists’ minds for many years.
In 1931, a man named Azzo Bassou was discovered by the local press in Marrakech in Morocco.
Azzo Bassou lived in the Dades Valley, near the town of Skoura.
The locals knew about him. According to them, he lived in a cave, ate raw meat. He walked naked (they put him in a bag just to take pictures) and used very basic tools.
They also described him as a person with low intellectual abilities in a primitive way.
He had the ability to pronounce some words, but many of them were illegible.
His forehead was sunken, there was a convex jaw, a large nose and long arms that reached almost to the knees.
In 1956, the French writer Jean Boulet, accompanied by ethnologist Marcel Gomet, arrived in the city to find out and study this case.
Scientists who saw him compared his skull with the remains of Neanderthals found and were amazed at their similarity.
The tabloids immediately dubbed him “the missing link”, portraying him as the last living Neanderthal.
In the midst of his research, Azzo died at the age of 60. True, there were two of his alleged sisters with similar facial features – Hisa and Herkaya.
Both women did very hard physical work with ease and were as wild as their alleged relative.
After careful study, scientists concluded that most likely these three were sick with microcephaly.
Microcephaly is a significant decrease in the size of the skull and, accordingly, the brain with normal sizes of other parts of the body. Microcephaly is accompanied by mental impairment – from not pronounced imbecility to idiocy.
