Human Evolution

A newly identified crocodile species, *Crocodylus lucivenator*, lived alongside early human ancestors in Ethiopia over three million years ago and likely preyed on them.

Fossil teeth found in Ethiopia reveal that early *Homo* and an unknown *Australopithecus* species coexisted 2.6 to 2.8 million years ago, challenging linear human evolution theories.

A new genetic study of over 3,200 Japanese individuals reveals a previously overlooked third ancestral group, challenging existing theories and linking ancient DNA to modern health conditions.
