An ape that lived 21 million years ago was used to a habitat that was both grassy and wooded. Corbin Rainbolt

Wooded grasslands flourished in Africa 21 million years ago – new research forces a rethink of ape evolution

Contrary to the idea that apes evolved their upright posture to reach for fruit in the forest canopy, the earliest known ape with this stature, Morotopithecus, lived in more open grassy environments.

Fossil teeth reveal how brains developed in utero over millions of years of human evolution – new research

Using a new equation based on today’s primates, scientists can take a few molar teeth from an extinct fossil species and reconstruct exactly how fast their offspring grew during gestation.

Humans evolved with their microbiomes – like genes, your gut microbes pass from one generation to the next

As early modern humans spread across the globe, their gut microbes genetically changed with them. Understanding the origins of gut microbes could improve understanding of their role in human health.

Revelations from 17-million-year-old ape teeth could lead to new insights on early human evolution

Cutting-edge analysis of fossil ape teeth reveals ancient seasonal change in Africa, long before human ancestors appeared. The method will be crucial for the future study of early hominins.
