Over the past 10,000 years, evolution in West Eurasia has been selecting for light skin, red hair and resistance to HIV and ...

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 ...

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 ...

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 ...

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 ...

Walking on two legs has long been considered a milestone in human evolution and one of our most defining characteristics. Until now, researchers assumed that the first humans originated in Africa and ...

Are humans natural born runners? Here’s why evolutionary and anatomical evidence suggests running was more central to our ...

The human body is often described as a marvel of "perfect design": elegant, efficient and finely tuned for its purpose. Yet, ...

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 ...

Researchers have demonstrated that intensified environmental variability (EV) can promote the evolution of cooperation through simulation based on evolutionary game theory. This result offers a new ...

The human body is a machine whose many parts – from the microscopic details of our cells to our limbs, eyes, liver and brain – have been assembled in fits and starts over the 4 billion years of our ...
