Humans walk heel-first far more consistently than chimpanzees, a strategy that may have helped our ancestors travel farther ...

Life on Earth began in a way that still boggles the mind. Around 4.5 billion years ago, a chemical process called abiogenesis occurred, where life emerged from non-life. Imagine a hot, watery mix of ...

One of the most prominent theories about the origins of human language is that our ancestors started to communicate using ...

This has been quite the wild year in human evolution stories. Our relatives, living and extinct, got a lot of attention—from new developments in ape cognition to an expanded perspective of a ...

Researchers at the University of Tsukuba have demonstrated that intensified environmental variability (EV) can promote the evolution of cooperation through simulation based on evolutionary game theory ...

How did humans become human? Understanding when, where and in what environmental conditions our early ancestors lived is central to solving the puzzle of human evolution. Unfortunately, pinning down a ...

For thousands of years, humans have selectively bred dogs to fulfill specific roles, ranging from guarding and hunting to herding and companionship. This deliberate shaping of traits has resulted in ...

Two of the traits that set modern humans apart from non-human primates are taller stature and a higher basal metabolic rate. Researchers have identified a genetic variant that contributed to the ...

Learn how early humans evolved at a much faster rate than other apes, adapting larger brains as they developed new ways to socialize. Skull diversity across great apes (orange) and gibbons (blue).

Until Homo floresiensis was discovered, scientists assumed that the evolution of the human lineage was defined by bigger and bigger brains. Via a process called encephalization, human brains evolved ...

Humans don’t have a defined mating season like deer or wolves. Here’s how evolution rewired our reproduction by blending biology, culture and social life into year-round intimacy. Unlike the rut of ...
