These bones and skulls range from 25,000 to 4.4 million years old and show many different stages of human and primate evolution.These fossils have been uncovered by paleoarchaeologists — scientists who study the material remains of the entire human evolutionary line.What’s more is that the mastodon’s remains show evidence of damage from human tools.All of this has been known for some time, and it was accepted to be one of the oldest sites in the Americas already.The classification of Sahelanthropus has been the most in question.The earliest australopithecines very likely did not evolve until 5 million years ago or shortly thereafter (during the beginning of the Pliocene Epoch) in East Africa.The old group in the rainforest continued to evolve, and two of its species remain in existence: the common chimpanzee and the bonobo. Imagine your mother holding hands with her mother, who is holding hands with her mother, and keep going back in time for 5 million years.The final clasping hand would belong to an unknown kind of an ape whose descendants evolved into chimpanzees, bonobos, and, ultimately, your mother.
This makes it difficult to assign calendar dates to the fossil remains of organisms from certain time periods, as in the case of the Mladec bones.) Modern humans began moving into Europe about 40,000 years ago.
For some time, experts have thought people first arrived in the Americas from the so-called “Old World” around 15,000 years ago.
Early explorers would have come across the Bering Land Bridge from modern day Russia to Alaska and down, and also spreading up from South America. Researchers now believe that they’ve found evidence of humans in the Americas that dates back over 130,000 years.
The study, published in the academic journal Nature, details and analyzes the remains of an ancient mastodon.
Authors posit that the mastodon was buried in a way consistent with human activity.
