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.

Your sense of privacy evolved over millennia – that puts you at risk today but could improve technology tomorrow

You have a finely honed sense of privacy in the physical world. But the sights and sounds you encounter online don’t help you detect risks and can even lull you into a false sense of security.
The Grotte Mandrin rock shelter saw repeated use by Neanderthals and modern humans over millennia. Ludovic Slimak

New research suggests modern humans lived in Europe 10,000 years earlier than previously thought, in Neanderthal territories

Stone artifacts and a fossil tooth point to Homo sapiens living at Grotte Mandrin 54,000 years ago, at a time when Neanderthals were still living in Europe.
