Neanderthals lived in small groups, study says



Cristina Kirchner has monopolized the political scene in Argentina

Genetic analysis of bones and teeth found in caves in Siberia is helping to decipher the social and family structure of Neanderthals. Little is known about how the species came together: remains of bones and teeth found in two Siberian caves are helping scientists decipher the social structure of the Neanderthals. By sequencing the DNA of these relatives of modern humans, the researchers analyzed the social life of a community of species that lived about 54,000 years ago. For the study, published Wednesday (Oct. 19), scientists analyzed the DNA of 13 Neanderthals, eight adults and five children and teenagers, and found an interconnected web of relationships, including father and daughter, and possibly an aunt or grandmother and nephew. The analysis also showed that all Neanderthals were blood relatives, indicating that the communities consisted of small groups of close relatives numbering 10 to 20 people. The study also concludes that it was women who migrated to other communities, while men tended to stay where they were born. Scientists believe that at least 60% of women came from other communities to join the families of their partners. The caves were the base of the group, which roamed the surrounding areas in search of raw materials and food. In addition to samples, numerous stone and bone tools were found in the Chagr caves. According to the researchers, hunting for horses, bison and other animals in the river valleys of the region provided the population with meat and skins. One of the largest genetic studies of Neanderthals. The analysis also found no evidence of interbreeding between Neanderthals and Denisovan hominids, the remains of which were found 100 kilometers from the caves from which the samples were taken. Published in the journal Nature, this is one of the largest genetic studies ever conducted on the Neanderthal population. The study was conducted by scientists from the Institute of Evolutionary Anthropology. Max Planck, including this year’s Nobel Prize in Medicine laureate Svante Paabo. Previous research has shown that Neanderthals were more sophisticated than previously thought, adopting customs such as burying the dead and making elaborate tools and jewelry. However, little is known about their family and social structure. “Our discoveries make Neanderthals closer and in some ways more human. They lived and died in small family groups, probably under extreme conditions. However, they managed to survive for hundreds of thousands of years,” said population geneticist Benjamin. Peter, co-author of the study. Who were the Neanderthals Neanderthals are a subspecies of archaic humans who split from modern humans between 315,000 and 800,000 years ago. Experts believe that its population ranged from 3,000 to 12,000 individuals that bred before becoming extinct 40,000 years ago. The small population has made this species prone to decline due to disease, low fertility, and competition with other animals. The reason for their disappearance remains a mystery, but theories include climate change, disease, and the emergence of modern humans. Compared to modern humans, Neanderthals had a stronger body and shorter limbs. Experts believe that they were hardy and could retain body heat well to live in cold climates. Previous research has shown that Neanderthals treated the sick with painkillers and penicillin made from plants and fungi. Fossils of species found show that 79% to 94% of them had some kind of traumatic injury. One study found that 74% of samples analyzed had injuries caused by animal attacks. The first Neanderthal genome was sequenced just over a decade ago by Paabo and other scientists at Max Planck. This work earned Paabo the current Nobel Prize. The study, published on Wednesday, is a continuation of that first sequence. cn/ek (DW, Reuters, DPA, AFP)

‘My power is really low’: NASA’s Mars Insight rover prepares to launch from the Red Planet



NASA Lander InSight He has delivered what may be his last message from Mars as he embarks on a historic mission to uncover the secrets of the Red Planet’s interior.

In November, the space agency warned that the probe could be running out of time as dust continued to condense and stifle InSight’s power.

“Spacecraft power generation continues to decline as windblown dust accumulates on solar panels,” NASA said in a statement. Update November 2. “The end is expected to come in the coming weeks.”

message shared NASA The InSight Twitter account tweeted on Monday: “My power is very low so this might be the last photo I can upload. Don’t worry about me: my time here has been productive and uneventful. If I can keep talking to my mission team, I will—but I will.” Subscribe here soon. Thank you for staying with me.”

My power is very low, so this might be the last photo I can upload. But don’t worry about me: my time here has been productive and uneventful. If I can keep talking to my mission team, I will, but I’ll sign here soon. Thank you for staying with me.

A geologist robot armed with a hammer and a seismograph first reached the barren expanse of Elysium Planitia in November 2018.

Since then, she has carried out geological excavations, taking the first measurements of earthquakes with a high-tech seismometer placed right on the surface of Mars.

Last month, the solar-powered car released an update to remind us of its time in space.

“I was lucky to live on two planets. Four years ago I made it safely to the second one, much to the joy of my family at first. Thanks to my team for taking me on this journey of discovery. I hope I can be proud of you.”

According to the published mission, Insight has measured more than 1,300 seismic events since it was published, and more than 50 of them had signals clear enough for the team to extract information about their location on Mars. Results.

The probe’s data also provided detailed information about Mars’ interior, liquid core, surprisingly variable remnants beneath the surface of an extinct magnetic field, climate and seismic activity.

old for Its launch in 2018NASA Chief Scientist Jim Green said the mission was “fundamental to understanding the origins of our solar system and how it became what it is today.”

NASA will not declare the mission complete until Insight confirms the arrival of two spacecraft orbiting Mars that are relaying their information back to Earth.

In 2018, the veteran rover announced the capabilities end of his 15 year stay Sending an incomplete photo of the Valley of Perseverance.

A severe dust storm darkened the sky around the solar-powered rover, shattering the sun and leaving behind a dark image with white spots due to camera noise. The transmission is interrupted before the complete image can be transmitted.
