Here are 10 interesting discoveries about human ancestors in 2021.

Ancient ‘Child of Darkness’ Skull Found in Cave

The remains of a young Homo naledi Doubts arise as to how she ended up on the deep and narrow corridors in South Africa. Scientists find a little boy’s skull which they called “leti” in the deepest part of the cave There was speculation that she might have been buried on purpose.

Leti lived between 335,000 and 241,000 years ago and was one of twelve H.naledi individuals discovered in the cave since 2013. H.naledi has been revealed to walk upright, standing regarding 1.44 m tall and weighing approximately 1.44 m. 40-56 kg

Meet the first human ancestor, Homo bodoensis.

A new analysis of a 600,000-year-old skull, first found in 1976, has revealed a new human species, Homo bodoensis, a possible direct ancestor of Homo sapiens. How do they move or interact with each other?

However, the researchers didn’t just discover the skull. But they have since reviewed the human fossil system. 774,000-129,000 years ago, a pile of evidence suggests that earlier species H.heidelbergensis and H.rhodesiensis are problematic. may be reclassified as Neanderthal. (Neanderthals), or H.bodoensis, further studies of Homo from this period may reveal previously unknown species. According to an October study published in the journal Evolutionary Anthropology,

New human species found, Homo bodoensis, living in Africa Cr. Ettore Mazza Human burials reveal missing lineage in Indonesia

The ancient human lineage never left a trace. But the discovery of a 7,200-year-old burial in Indonesia revealed a previously unknown human lineage. who died at various points Genetic analysis of the old woman’s remains revealed that she was a distant Aboriginal and Melanesian relative. or indigenous peoples on the islands of New Guinea and the western Pacific

This woman carries a significant proportion of DNA from the ancient human race known as Denisovans. Like Aboriginal Australia and New Guinea, perhaps Indonesia and the surrounding islands might serve as a meeting point between modern humans and Denisovans. This story was published in the journal Nature in August 2021.

The remains of a skull and teeth were discovered in South Sulawesi, Indonesia.  Cr.Hasanuddin University The oldest intentional burial in Africa occurred 78,000 years ago.

A child was buried deep in a cave in Kenya some 78,000 years ago, making it the oldest recorded human burial in Africa. The three-year-old boy, nicknamed “Mtoto” in Swahili, means “child,” curled up as if asleep. Researchers found her head was placed on a cushion or pillow.

There is an even older H.sapiens burial. Including burials that date back 120,000 years in Europe and the Middle East, but Mtoto’s remains are the earliest intentional human burials in Africa. According to a study published in May in the journal Nature.

Massive genome analysis reveals the importance of the Arabian Peninsula.

The largest-ever Arab genome study reveals the importance of the Arabian Peninsula to early humans who migrated from Africa, looking at the DNA of 6,218 Middle Eastern adults and comparing it with the DNA of 6,218 Middle Eastern adults. Ancient and modern people from all over the world.

The analysis revealed that Middle Eastern groups have made a huge genetic contribution to the European community. South Asia and South America This is likely because Islam has spread throughout the world in the past 1,400 years. People of Middle Eastern descent have interbreeding with those populations. Moreover The results also indicated that Arab ancestors separated from early Africans regarding 90,000 years ago, at the same time that European and South Asian ancestors separated from Africans. This story was published in the journal Nature Communications. last october These findings support the idea that Early humans leave Africa and they had passed through Arabia at that time.

The genes from the first Americans matched the genes from the Australians.

The first Americans to cross the Bering Land Bridge and enter North America during the last Ice Age. They have something special in their genes. That’s a piece of ancestral Australasian DNA. The Australians are indigenous from Australia, Melanesia, New Guinea and the Andaman Islands in the Indian Ocean.

These Australasian DNA segments still exist today. Later generations in Native American peoples, however, not all Native American groups have this DNA.

which made it possible to assume that There may be more likely a connection between first American ancestors and Australasian ancestors in Beringia or Siberia, according to an April study published in the journal Proceedings of the National Academy of Sciences.

Oldest fossil footprints found in the Americas

When the first Americans arrived in the last Ice Age It’s still a controversial issue. However, 60 footprints were found in the bottom of an ancient lake in White Sands National Park. new mexico It was between 23,000 and 21,000 years old, which was a sign that people came here quite quickly. That is regarding 13,000 years faster than the discovery of Clovis a year ago.

These footprints are not the oldest evidence of humans in America. But it’s definitive evidence that people lived here at the height of the Last Glacial Maximum, which lasted from 26,500 to 19,000 years ago, according to a September study published in the journal Science.

Oldest fossil footprint found in the bottom of a lake in the Americas Cr.National Park Service, USGS and Bournemouth University Oldest Denisovan Fossil Found

Denisovan fossils The oldest known is regarding 200,000 years old, according to newly discovered bones in a Siberian cave.

Denisovans may have been widespread throughout Asia. According to research on DNA extracted from the discovered Denisovan fossils. But their sans are rare. So far, there are only six known Denisovans, five from Denisova Cave in Siberia and one from China. With this new discovery Researchers therefore have fossils from three additional Denisovan individuals from Denisova Cave.

If researchers still find that Denisovan persists Perhaps this mysterious species will no longer be a mystery to us in the future.
