Kinetic scientists found a fossil believed to belong to humans’ ancestral cousins, who lived more than two million years ago. The finding was made in South Africa and they believe it will bring more clarity to the theory of evolution.
It turned out that the fossil belongs to a species with large teeth that are two million years old and would provide a different perspective on how humans evolved. They added that it would come from a male known as Paranthropus robustus, a “firstFrom Homo erectus, direct ancestor of modern humans.
“Most fossil remains are just a single tooth, so having something like this is very rare, we’re very lucky”, expressed to the BBC the doctor Angeline Leece. “Over time, Paranthropus robustus likely evolved to generate and withstand greater shocks caused by biting and chewing food that was more difficult or mechanically difficult to handle with its teeth and jaws “added.
“Although we are among the ancestors who eventually triumphed, the fossil record suggests that two million years ago it was much more common to see Paranthropus robustus in the area than Homo erectus”, continuously.
For his part, Jesse Martin, one of the fellow researchers, said so “handling the fossil pieces was like working with wet cardboard”, in which he explained how he used plastic straws to soak up the last bits of embedded dirt. “This discovery of the skull is a rare example of microevolution within human lineage,” added.
They reported that Paranthropus robustus had large teeth and small brains, unlike Homo erectus, which had large brains and small teeth. Scientists note that it is possible that a more humid environment due to climate change has reduced the amount of food available to them.
