Found the remains of an unknown science of human ancestor – TVNZ

A group of researchers under the leadership of Yohannasa Dr. Haile Selassie (Dr Yohannes Haile-Selassie) – curator of physical anthropology at the Cleveland Museum of Natural History in the US (curator of physical anthropology at the Cleveland Museum of Natural History) – discovered in Ethiopia jaw and teeth apelike human ancestor who lived 3.3-3.5 million years ago. Scientists have found that the remains belong to a woman before species unknown to science. He was given the name Australopithecus deyiremeda. Thus, the situation with our ancestors even more confused. And who exactly we come from, it was quite unclear.

First considered the mother of Lucy, whose remains were also unearthed in Ethiopia in 1974. Lucy, aka Australopithecus afarensis (Australopithecus afarensis), lived 3.2 million years ago. Scientists believe that this species and walked up the steps of evolution until it turned into us. But then in Kenya found kenyanthropus flat-faced (Kenyanthropus platyops), Chad – Australopithecus Bahr el gazalsogo (Australopithecus bahrelghazali), who lived around the same time with Lucy. Yes, and “compatriot” is now detected – previously unknown species Australopithecus deyiremeda – was also her contemporaries. All of them are contenders in our foremothers. But there is another – older. My name is Hardy, she Ardipithecus ramidus. She lived 4.4 million years ago in Ethiopia and was no longer a monkey.

If you believe Haile Selassie, the female species Australopithecus deyiremeda, which means “close relative”, different from his contemporaries jaws and teeth – just the fact that it was found.

– We have identified fundamental differences in detail the anatomy and morphology of the teeth and the upper and lower jaw, – said the scientist Bi-bi-si . – This new species is very powerful jaws. A teeth – small. Fang, for example, is less than all the resources of people, we have described in the past.

The difference in the teeth, according to anthropologists, suggest that their owners ate different food.

Answer the question, “From whom did we come from?” Now there is. And to find him, said Haile-Selassie, need to continue the search for fossils. Scientists have to understand how to get along with each other different types of our potential ancestors. Pairing it? Whether mixed?

BTW

“Missing Link” in the absence of which opponents gleefully pointed out by Charles Darwin, lived on Earth 2 million years ago

Paleohudozhnik Gurch John (John Gurche), using the method of the Russian professor Gerasimov restored the image of the boy, whose remains were found in South Africa in 2008. He lived much later Lucy and Ardi other. That is, standing up on the evolutionary ladder. And now considered to be our direct ancestor – maybe even the missing link between ape and man, the lack of which for many years gleefully pointed opponents of evolution theory of Charles Darwin. Discovered in South Africa remains attributed to such “transitional model” between Australopithecus – almost ape – and almost modern Homo habilis (Homo habilis).

The sensational discovery – on account of a professor of evolutionary biology Lee Berger (Professor Lee Berger) from the University of Witwatersrand in Johannesburg (Witwatersrand University in Johannesburg) . It is made during excavations of a cave in South Africa’s Malapa (Malapa Cave) near Sterkfontein (Sterkfontein), where in the past found bones of ancient human ancestors. The remains belonged to 13-year-old boy – a teenager. At first it was called sediba (Sediba). Which is translated from the local – South African dialect – meaning “Well”. Later renamed Karabakh. What does the “answer.” The answer, of course, skeptics creationist.

The scientific name of the species, which belonged to the remains of the cave, is approved: Australopithecus sediba.

Growth boy was about 130 centimeters. I weighed under 30 kg. Brush was such that it allowed to make tools. His fingers Karabakh could deftly manipulate small objects.

At the same time, the “missing link” were quite long arms and a well-developed thumb by which it can move around, clinging to the branches. This “link” is still like a monkey.

– Apparently, it is combined the right walking with jumping from tree to tree. – Says Berger. – In this way, the structure and stop points.

Basins for “ancestors” were already quite human – across the width. Legs – long, allowed to run fast.

The size of the brain-Karabakh and his people was a third of the modern – a small melon-collective farm. But evolution has touched this important body. He prints left on the skull, scientists have determined that the Australopithecus sediba were well developed frontal lobe of the brain. Almost like a modern man.

The teeth were relatively small. This indicates that the “missing link” was not required hard to chew. Rather, “it” has learned to cook. Perhaps the fire.

fly in the ointment

You’re not a woman, and a baboon?!

famous Lucy skeleton – one of our foremothers – was found during excavations, which led paleontologists Donald Johanson and Tom Gray (Donald Johanson and Tom Gray). It was named as the heroine of the song The Beatles Lucy, which sounded from the cassette deck of scientists at a time when they are “washed” discovery.

And now – after decades – Gary Sawyer (Gary Sawyer), Mike Smith ( Mike Smith) from the American History Museum (American Museum of Natural History in New York), joined by Scott Williams (Scott Williams) from New York University (New York University) , who recently took up another reconstruction of the skeleton of Lucy, We noticed something strange in it. Namely, foreign bone.

Scientists confused one of the spinal vertebrae, which eventually turned out to be from a baboon. That is, from the apes of similar size.

Where did the vertebra from a monkey? How could worm his way among the other bones? Riddle. After all, where Lucy found, there was no baboons.

So maybe Lucy’s fake? Hoax?

Scott Williams says that his discovery was not “cast a shadow” on all available Skeleton foremothers. He seems to be real. And the remaining 88 bones really belong to Australopithecus afarensis. But as they say, the precipitate is …
