A recent study has revealed that males of some of humanity’s earliest ancestors …

Most people imagine our early primate ancestors swinging through lush tropical forests. But new research shows that they were braving the cold. As an ecologist who has studied chimpanzees and lemurs in the field in Uganda and Madagascar, I am fascinated by the environments that shaped our primate ancestors. These new findings overturn decades of assumptions about how – and …

Early human ancestors may have learned to walk upright on two legs up in the trees rather than on the firm ground of Africa’s ancient savannah. A first-of-its-type study led by researchers at the Max Planck Institute of Evolutionary Anthropology in Germany has identified a link between the foraging strategies of Tanzania’s Issa Valley chimpanzees among woodlands and the ape’s …

Ancient, fossilized teeth, uncovered during a decades-long archaeology project in northeastern Ethiopia, indicate that two different kinds of hominins, or human ancestors, lived in the same place between 2.6 million and 2.8 million years ago — and one of them may be a previously unknown species. The discovery provides a new glimpse into the complex web of human evolution. Ten …

The moment a creature dies, its DNA begins to break down. Half of it degrades every 521 years on average. By about 6.8 million years, even under ideal preservation conditions in cold, stable environments, every meaningful trace is gone. That’s a huge challenge when trying to understand our evolutionary history more deeply: Two-legged primates emerged 7 million years ago in …

The human family tree is looking more and more like an unruly bush. Paleontologists have now uncovered the teeth of two different ancient human lineages at the same site in northeastern Ethiopia. The discovery collapses the distance between the first of our genus and the last of the australopithecines in eastern Africa. The two probably coexisted. Related: Lucy Is 50: …

Credit: Ken Zirkel,the Museum of Natural History By the time “Lucy” took her final steps across the Ethiopian landscape 3 million years ago, her kind may have been living in a social world far more combative than we once imagined. A new study reveals that males of Australopithecus afarensis — the species that includes the famous fossil — were dramatically …

New research published in the American Journal of Biological Anthropology highlights the extreme sexual dimorphism in early human ancestors, revealing that some species like Australopithecus afarensis and A. africanus exhibited striking size differences between males and females. This newly uncovered information, led by anthropologist Adam D. Gordon of the University at Albany, challenges previous assumptions about early hominin social structures …
