This skull comes from the Luo Bai family. It is reported that the Robust Pangren is a close relative of Homo erectus, and Homo erectus is considered the direct ancestor of modern humans. These two species lived in the same period, but the Luobai people died out earlier.

Recently, Australian researchers claimed that a human “cousin” discovered in South Africa 2 million years ago The skull provides more excavable information for human evolution.

The research team said that most of the fossils are scattered teeth, so it is very rare and very lucky to find such fossils. Judging from the picture, the”good teeth” of this skull are very intact.

In 2018, researchers from the University of Melbourne discovered this skull fragment at the Drimolen archaeological site in northern Johannesburg, South Africa. In the past few years, archaeologists have pieced together and analyzed the fossils, and the research results were published in the November 10, 2020 issue of”Nature Ecology and Evolution”.

It is reported that Robusta has large teeth and small brains, which are different from the small brain teeth of Homo erectus. The former mainly eats hard plants, such as tubers and bark. Homo erectus with smaller teeth is more likely to eat both plants and meat. As time goes by, it is likely that the Luo Baishi Pang people have evolved to be able to emit and withstand greater strength when biting and chewing food.

Researchers said that although Homo erectus eventually won out in evolution, the fossil record of 2 million years ago shows that on land, Robusta is much more common than Homo erectus.
