Stasigenesis: The strange species evolution has stopped at a very long time

Stasigenesis: The strange species evolution has stopped at a very long time 86

We are used to believing that a species should become something new in any way. Evolve, evolve and that’s all. But practice shows that change is not always the key to a successful future. In the end, why break something that works so well? Some animals also decided so. By being lazy and without knowing it, became the culprits of a new type of speciation – stasigenesis.

You can not differentiate, whether it is a dinosaur or a bird …

We have all heard of such a term as “living fossil”. For those who have not heard, a living fossil is an organism that has not really changed much for millions of years of its evolutionary lineage, from the time it appeared. More scientifically, such species are called relict .

The clearest example of a living fossil is crocodiles. The ancestors of crocodiles lived in the time of dinosaurs and the only thing that distinguished them from modern reptiles was their size.

In order for a living fossil to receive the honorary status of the grandfather of the entire planet, scientists look for a fossil of a similar representative and determine its age. Further, the remains are compared with a modern animal. And if there are more similarities than differences, then stasisgenesis was successful, congratulations.

Opossums are one of the oldest mammals. 66 million years have passed, but they have not changed much (don’t worry, this oposum is not 66 million years old, it just has a genetic malfunction due to which wool does not grow)!

But what about the main rule of evolution: “Adapt or die!”? Well, in this regard, relict animals can be called real lawless! After all, the conditions in which they live have remained unchanged for millions of years, so you don’t need to adapt to them! Deep water, islands, what is it, the whole of Australia – all these places have become deposits of living minerals!

And now, to the examples. Many people think that relict species are completely nasty arthropods. But the big-eyed charm – deer with this majority will not agree.

No, the grass is not so high, it’s a microscopic deer!

A whole family of artiodactyls, this mini-deer is a little larger than a hare! Cows, pigs and other artiodactyls – are all descendants from a distant cousin of this crumb. But this deer has practically not changed. And why change when its ancestors and the ancestors of its ancestors have been hanging out in the jungle for several million years, where the conditions are always stable, hot and humid?

With such teeth, he no longer looks cute ..

To see another victim of stasigenesis, we have to go down to a depth of 500-1000 m. The Goblin shark is not a beauty, but the only surviving representative of the Mitsukurinidae family .

Also named a Goblin Shark or Elfin Shark. It was first discovered in the 19th century!

Thanks to deep waters, where conditions have remained unchanged for millions of years, the bizarre shark was more than able to outlive its relatives. Its ancestors plowed the expanses of the seas 93 million years ago and since then this old alien-look like creature with extendable jaws has not changed much.

Yes, yes, a shark with extendable jaws. Congratulations on your new nightmare story

Well, and what article about strange animals can exist without Australia? The entire ecosystem of this inverted continent can be called relict. Australia’s animals and plants have long been completely isolated from other continents.

First animals (platypus, echidna), marsupials and many flightless birds are living echoes of the past, which are not adapted to the fierce competition of the big world. If they would move to the Eurasian continent, they would be an immediate prey by local wolves, foxes and bears.

The fauna of Australia and New Zealand is very susceptible to any external influences. Humans and introduced predators exterminated many endemic sites of these places (in the photo a giant bird Moa. It was exterminated by the indigenous tribes of New Zealand).

Polar vortex: “wild” winter is coming in the US, Northern Europe and East Asia after the 16th of January

Polar vortex: "wild" winter is coming in the US, Northern Europe and East Asia after the 16th of January 95

In the upper atmosphere above the North Pole, experts saw a rapidly swirling vortex of cold air that could bring severe frosts to the United States, Northern Europe and East Asia. Serious cold snap and snowy weather are expected after January the 16th.

Snowfalls and a cold snap hit South Korea since the start of 2021, hitting historic snow maximums and temperatures. In the country, for the first time since 1964, television and newer communications are sending people cold snap warnings:

The situation is similar in Japan, where a new snow storm hit historic highs:

On January 7, the thermometer In Beijing dropped to -20 degrees Celsius, breaking the 1966 record. In other regions of China, the temperature is also not sugar, and you can only move around in special uniforms:

The cold even reached Taiwan, where the temperature in some areas dropped below freezing point, snow poured down and people realized that rice terraces can be used as a ski jump:

Even more snow went to Spain, where on January 6, 2021, a temperature of -34.1 ° C was recorded – the lowest on record. After that, a snow storm hit the country, which has not been seen for 80 years:

The same thing happens in Canada and in the northern states of the United States:

It seems that after a stratospheric warming, the subpolar vortex began to split:

The vortex itself is a standard phenomenon. However, this time experts were surprised at his movement. It is possible that in the near future it will be divided into two parts. 

Scientists associate the strange behavior with the changed climate in the Arctic, which has become warmer. From September to December, the amount of ice cover decreased significantly.

The polar vortex is a low-pressure region located in the stratosphere and filled with cold air. When the jet stream of air that holds the vortex weakens, the low pressure area moves south. 

As the ice shrinks, more moisture will move inland. It will turn to snow, so snowfalls are expected. Snow, in turn, reflects heat, leading to a cold snap.

Hospital in Naples was evacuated after a new, huge sinkhole appeared

Hospital in Naples was evacuated after a new, huge sinkhole appeared 96

Eyewitnesses said they heard a loud crash at dawn when a huge hole in the ground formed outside the Ponticelli Ospedale del Mare hospital in eastern Naples.

Early in the morning of January 8, 2021, a sinkhole occurred in the parking lot of a clinic in Naples. The depth of the formed cavity is about 20 meters, the total area of ​​the hole is about 2,000 square meters.

No casualties were found at the scene; firefighters say the sinkhole “affected an area of ​​about 500 square meters” and engulfed several cars parked near the hospital.

As the press writes and as a little can be seen from the videos, rescuers and firefighters were running around the pit together with the governor of the area.  But who should be there in the forefront are Italian geologists, since Naples stands in the very center of the volcanic system known as the Phlegrean Fields.

If the surface collapsed, moreover – the surface reinforced with concrete and reinforced from below with some kind of communications, then we are talking about serious soil deformations caused by the activity of magma.

Italy has been in doubt since the summer of 2020, because swarms were observed there in very atypical places in May, and according to the forecasts of old Italian seismologists, who had witnessed many strong earthquakes, it should have boomed in the August region.

Fortunately, nothing bad happened to Italy and there was no big earthquake. But, since there are swarms, it means that something is being prepared, the magma is gathering strength. 

Following this particular sinkhole event – an obvious sign that a major earthquake in Italy is already very close.

A new great pandemic cycle has begun (again) in China

A new great pandemic cycle has begun (again) in China 97

In the first months of 2020, the whole world with a certain fright followed the events unfolding in China, where people fell on the streets during the day and astronauts wandered, and in the evening crematoria began to smoke. And now, with the onset of December, the cycle seems to be repeating itself.

Shunyi area in Beijing, where the authorities announced “wartime status” the day before. As you can see in the videos, thousands of people are lined up in the queue for mandatory testing:

Dalian city, where “wartime” is also declared. Neighborhoods are blockaded, people are walled up in entrances, familiar characters of George Lucas roam the streets:

Chinese ‘rescuers’, before performing a combat mission:

Chengdu City:

Daluo Port, Yunnan – tourists came for adventure and they received the ‘time of their life’ after leaving the ramp:

If something happens in Beijing, it does not mean that tomorrow the same will happen everywhere. However, the trend towards such dynamics is observed and, as the practice of the first wave of the pandemic has shown, all countries and people, to one degree or another, have taken into account the ‘Chinese experience’. 

Therefore, one must think that everything will now be in peace, as in spring – a new global round of the fight against the Covid has begun in China, a new great pandemic cycle!
