Australopithecines were less intelligent than modern apes

Australopithecines were less intelligent than modern apes 92

Our ‘Ancestor’ – Australopithecus (Australopithecus), the most famous skeleton that Lucy is known for is, as it turns out, was less intelligent than modern apes.

Lucy knew how to walk on two feet and looked far more humanoid than a chimpanzee. Her brain was larger than that of a chimpanzee, but Lucy’s blood was circulating more slowly to her brain.

The rate of blood flow to the brain indicates the speed of its metabolism and the level of intelligence of its owner.

There are special channels for the arteries in the skulls of anthropoid apes and humans. The wider they are, the more blood goes into the brain.

Scientists have examined the size of these channels in 96 skulls of modern chimpanzees, gorillas, orangutans, as well as in the skulls of 11 Australopithecus, including Lucy.

It turns out that modern gorillas have the same brain size as Lucy, but the blood flow rate in their cranial ducts is twice as high as hers.

When the skulls of Australopithecus are compared to the skulls of chimpanzees and orangutans, it turns out that with all these monkeys, blood flow to the brain is also faster than that of Australopithecus.

Scientists believe these results are incredible. It turns out that Australopithecus is much less “sensible” or, in other words, more stupid than modern anthropoid apes.

In the evolutionary branch, Australopithecuses are between apes and humans, based on a number of traits, including those related to brain size and the development of intelligence. However, such a classification seems to be incorrect.

Prof. Roger Seymour, lead author of the study, says:

“At first glance, the connection between brain size and intelligence seems logical, since size is related to the number of neurons. However, the capacity for knowledge depends not only on the number of neurons, but also on the number of synapses – the connections between them. These connections control the flow of information in the brain, ie. more synaptic activity leads to more information being processed. “

The human brain consumes 70% of its energy for synaptic activity. The amount of energy proportionally depends on the blood supply that supplies the brain with oxygen.

Although our brain represents only 2% of our body weight, it consumes 15-20% of the energy produced by the body and accounts to 15% of the blood used to provide it with oxygen.

Tesla autopilot sensor recorded “ghost” in an empty cemetery

Tesla autopilot sensor recorded "ghost" in an empty cemetery 98

A Tesla electric car with an activated autopilot function recorded an invisible person who allegedly moved around the cemetery. Social network users jokingly noted in the comments that, most likely, this is some new function from Elon Musk, which allows you to see ghosts.

In the United States, a Tesla electric car with an activated autopilot function recorded an invisible person who allegedly moved through a cemetery.

The corresponding video was posted by Twitter user Ovidiu Maciuc.

The recording shows how a silhouette of a man appears on the monitor of an electric car, moving around the cemetery. After that, the driver raises the camera and starts filming the graveyard through the windshield, but there are no people there.

After some time, the “ghost” went in the opposite direction from Tesla and disappeared from the on-board computer screen.

Social network users jokingly noted in the comments that, most likely, this is some new function from Elon Musk, which allows you to see ghosts.

For many though, if you take into account the comments, the video seemed rather creepy. Some even tried to guess what the navigation system actually showed.

Some users thought the system could recognize ghosts. Others refuted this version and said that the reason for all this is an insufficiently accurate sensor, which was used for the equipment of the Tesla car.

Earlier it became known that Tesla electric cars in the near future may receive a new function with which they can talk with pedestrians. For this, American cars will be equipped with special external speakers. 

In addition, Tesla cars in the future will receive the option to change the horn and sound of movement at low speeds to warn pedestrians. According to Elon Musk, among the sounds of movement there will be the sound of the clatter of a horse’s hooves, and as a whistle – the bleating of a goat.

Mysterious energy source melts Tel Aviv sidewalks, leading to the evacuation of several buildings in Israel

Mysterious energy source melts Tel Aviv sidewalks, leading to the evacuation of several buildings in Israel 99

About two weeks ago, Tel Aviv residents noticed that the concrete surface outside their homes was heating up and steam was coming out of the ground. Tests showed that steam that reached 60 ° C (140 ° F) was water based.

The witness explains: “I was afraid that there was a power line in the area and asked a worker to dig out the ground with a shovel. Steam suddenly came out. I imagined it was probably a geyser. It seemed to me that this was a geological incident – also because there were no problems with electricity in the building. “

Although the experts did not find any hazardous substances or any risk to the stability of buildings at the site, residents as well as kindergartens in the area were evacuated.

Officials described the heat source as “trapped energy” of unknown origin.

Work continues, steam is still rising and the ground is still hot. It is currently unclear what is causing the warming. Note the hole dug in the area. The area is still blocked.

Mysterious origins

City officials said they will “continue to monitor the temperature of the earth, which is expected to cool down for a long time, and will continue to investigate the causes of the unusual event.”

Israel Electric Corporation has not found a connection between heat and power in the area.

The Israel Geological Survey confirmed the rise in temperature after testing ground and water temperature levels, but said it has not yet found an explanation.

Despite their best efforts, municipal officials, the fire department, Israel Electric Corporation and the Ministry of the Environment have yet to find a source of heat.

Meanwhile, the Tel Aviv municipality has informed dozens of evacuees that they can return to their homes. However, residents are not going to return until they receive a detailed account of the source of the mysterious event.

“They evacuated us because they were concerned about our safety, and now they are urging us to return without any convincing explanation. How can you be sure that there is no more danger? “

The night sky in southern Taiwan shows a weird red moon alarming netizens: 2021 disaster year omen?

The night sky in southern Taiwan shows a weird red moon alarming netizens: 2021 disaster year omen? 100

Some people in Chiayi, Taiwan took pictures of a large dark red moon hanging in the night sky on the first night of 2021 and uploaded them to Facebook. There are also people in Tainan who have photographed the rare “red moon”. The weird scene has aroused heated discussions among netizens. Some people worry that an earthquake may occur, while others suspect that this is a precursor to the year of disaster in 2021?

Yesterday, on January 1 at about 8:00 in the evening, Chiayi residents shared a photo of “2021’s first red moon” on Facebook. As you can see in the photo, the weather was quite good at that time. There was a clear big round moon in the night sky, but it was a dark red moon, which was very different from the usual moon.

Later, people in Kaohsiung and Tainan also posted photos of the red moon they had taken.

The weird and rare “big red moon” immediately attracted the attention of netizens. Some people think that such a sight is caused by air pollution, and some people think that the red moon is “extremely beautiful”, but many people worry about whether it is a harbinger before the disaster ? 

“Hope is not a harbinger of disaster~”, “A harbinger of disaster in 2021???”, “It looked uneasy”, “After seeing the red moon, I hope everyone will be safe”.

Some netizens worry that this is a pre- earthquake omen.

“Remember the red moon before the 921 earthquake (omen)”, “earthquake precursors”, “I feel that there will be an earthquake again recently”, and “It seems that 2021 will be another year of bloody disaster.”

The British clairvoyant Craig Hamilton-Parker published his prediction for 2021 on YouTube in December last year, stating that, as far as the world is concerned, 2021 will be a year full of social unrest, armed conflict and political changes. There will be difficult times right now until 2025.

He also predicted that the biggest worry is climate and earthquakes. A tsunami will occur near Japan. Large earthquakes will occur in the Himalayas, Iran and the Americas. There will also be problems such as floods, dams bursting, and huge icebergs obstructing shipping. Until 2025, the severity of environmental problems will gradually increase.
