As quoted from IFL Science, Wednesday (11/25/2020) fossils primordial man which lived around the tip of Africa about 2 million years ago are fossil species Paranthropus robustus in the best condition ever found.
Order primordial man It was first discovered in 2018 by researchers from the Department of Archeology at the University of La Trobe, Australia during excavations at the Drimolen Main Quarry north of Johannesburg, South Africa.
Findings published in the journal Nature Ecology & Evolution this is an important finding for science.
The reason is, researchers can finally provide new insights into this mysterious ancient human species.
For example, researchers say if fossils Paranthropus robustus apparently lived at the same time as mankind’s direct ancestor, that is Standing man.
This indicates that both species primordial man shared the same landscape and time around 2 million years ago.
“These two very different species, Standing man with a relatively large brain and small teeth whereas P.robustus with relatively large teeth and a cerebellum, representing a different evolutionary experiment, “said Angeline Leece, lead author of the study.
Not only that. The research team also believes that there are anatomical changes Paranthropus robustus caused by local climate change in Africa.
As the area became drier, food became scarce, and eventually forced Paranthropus robustus to eat the tougher vegetation.
They develop chewing adaptations in response to environmental changes.
Researchers also call this event a rare example of microevolution in the human lineage.
“P.robustus amazing because it has a number of features on skull, jaws, and teeth showing that it is adapted to eat a diet consisting of very hard foods, “explained David Strait, professor of anthropology at the University of Washington.
Unfortunately, even though they managed to survive on a difficult diet and adapt to the changing African environment, these human relatives still did not survive and had to become extinct.
