As the monkey learned to walk on two legs?
Source:
look like baboons — they are we will mention just below.
Millions of years ago was charged with four limbs. In the course of evolution, they somehow learned to walk on two legs, but scientists still cannot come to a consensus about the causes of bipedalism. However, recently, researchers from Germany one small step closer to solving this mystery. They found and studied the bones of anthropoid apes that lived on our planet approximately 11.6 million years ago. The structure of their bodies hints at the fact that they originally learned to walk in trees, and then, most likely, began to walk on land.
Scientists hundreds of years can't understand why people walk upright due to the fact that the bones of our ancestors very badly preserved to the present day. In the mid-twentieth century, paleontologists were able to dig up fragments of the skeleton lived 13 million years ago primates, but limb bones are almost always corrupted. This was the main problem in the reconstruction of ancient ways of movement of monkeys. But despite this, scientists still encounter some assumptions.
How did bipedalism?
For Example, in examining the bones that lived more than 4.4 million years ardipithecus (Ardipithecus ramidus), paleontologists have found that our ancestors knew how to walk with four limbs, and with the help of two. Perhaps, walking on two legs arose in the course of how ancient primates moved among the trees, hanging on branches with two or four limbs.
it looked like Ardipithecus ramidus according to the artist
Recently, researchers from Tubingen University (Germany), shared new theory of the origin of bipedalism in humans. Between 2011 and 2018 in the South of Germany they were found the remains of the skeleton lived 11.6 million years ago primates species Danuvius guggenmosi. In particular, it examined the ulnar, femur and tibia, and vertebrae of our ancestors. Excellent preservation of the bones of the hands and feet has allowed scientists to restore the appearance of ancient primates.
Bones apes Danuvius guggenmosi
According to a scientific journal , apparently the ancestors of gorillas and humans were similar to modern baboons. Their growth reached 110 centimeters, and a large part of their time they spent in the trees. They had quite a long arm, the elbow joint is flexible and strong fingers for grasping branches — these are the features now inherent in many of the manlike apes.
Monkey Danuvius guggenmosi lived more than 11.6 million years ago
But the feet of the ancient Danuvius guggenmosi monkeys was more similar to human. The structure of the femur and tibia hinted to the scientists that these creatures sometimes walked on two legs, and not bent as in chimpanzees and gorillas, and direct. Toes had good strength, therefore scientists have come to the conclusion that lived millions of years ago apes were able to easily move through the branches of the trees on two legs.
It is likely the next step in was bipedalism not on the trees and on the ground. However, this theory is nothing proven to do this, paleontologists need to dig up more fossilized bones of ancient primates. It is desirable that they were minimally damaged by time.
