Paleontologists have figured out what kind of lifestyle he led a “Primate” of humanity Lucy

Палеонтологи выяснили, какой образ жизни вела "прамать" человечества Люси

. Paleontologists have found new evidence that the famous Lucy, is now regarded as the “mother” of our family, spent a lot of time on the branches of trees, and not only traveled across the plains, according to a paper published in the journal PLOS ONE.

“For us, it may seem unique that early hominini, like Lucy, had the ability to walk on two limbs and spent a lot of time climbing trees. Of course, Lucy herself didn’t know about its uniqueness and just lived in the ancient Land, walking the land, climbing the trees where she was looking for food, and wove the nest, until then, until her life was cut short after an accident and falling on the ground,” says John Kappelman (John Kappelman) from the University of Texas at Austin (USA).

Today among paleontologists and anthropologists no consensus on where is the birthplace of modern man and when the first representatives of our race. This role is equally claimed by two of the area of Africa, national Park awash, Ethiopia “cradle of mankind” at Olduvai gorge in South Africa.

In favor of the former candidate says that on the territory of the region in 1972 was found the remains of “Lucy”, a young female Australopithecus afarensis who lived is 3.18 million years ago in the region of afar in Ethiopia. Her limbs were adapted for bipedalism, and many features of the anatomy was similar to the way how people that leads many scientists to believe that “Lucy” is a kind of “mother” of the genus Homo.

Today “Lucy” were strong competitors – “Littlefoot” and “man star” Homo naledi from South Africa, so the researchers with a new interest to study their remains in an attempt to find the real ancestor of the genus Homo.

In August of this year, Kappelman and his colleagues found evidence that Lucy died, torn from the tree and hit the ground, that raised some doubts in her “birthright” of some scientists. Other paleontologists embraced the idea of Kapelman hostility, expressing doubts about the reliability of the used data and methods of analysis.

Responding to criticism, the authors re-analyzed more than 35 thousand “slices” of the bones obtained with the “transmission” of a computer tomography known all her remains, and compared them with the remains of two other Primate species – humans and chimpanzees.

As the scientists explain, the style of life of the animal affects the way his skeleton is in those places that are under pressure, thicken bones, and those bones which are loaded less, on the contrary, become more thin. Therefore, the comparison of bones of closely related species allows us to understand where he lived and what he did to one of their owners, knowing the ecological niches of his relatives.

“Tennis players are a great example of this phenomenon – the bone in their “raketnoj” hand much tighter than its counterpart in the second hand,” — continues scientist.

Similarly, human bone gradually “thicken”, if you look at them from the side of the skull in the direction of feet that indicates that we are mainly terrestrial way of life. For chimpanzees are characterized by reverse painting the bones of their arms and shoulders are noticeably thicker and larger on top, due to their arboreal lifestyle.

For Lucy, as it turned out, was characterized by completely different picture – the thickness and strength of the upper and lower parts of her bones were about the same, which means that it takes an intermediate position between humans and chimpanzees.

According to the authors, this result suggests that avarskii the Australopithecines spent approximately equal time on the ground and on tree branches. Scientists believe that Lucy and her relatives have built nests in the trees, protecting them from predators during sleep or periods of rest. Day avarskii the Australopithecines probably were down to earth and looking for food in savannas and plains, not avoiding and forests.

All this, according to Kapelman and his colleagues does not refute, and speaks in favor of the fact that Lucy and her relatives were indeed “transitional” form between our ancestors of the genus Homo and ancient hominids.
