Using new radiocarbon dating on footprints preserved in the gypsum-rich ground in White Sands, researchers have confirmed that humans roamed North America 23,000 years ago. The finding solves a long debate questioning the age of these footprints.

The world's oldest human fingerprint has been discovered at an archaeological site in Spain. The fingerprint was dated at 43,000 years old and is believed to have come from a Neanderthal.

It's not a simple case of "follow the leader" when it comes to baboons on foot. Researchers have made a surprising discovery on why they appear to move in an orderly line, and it's something that can help us better understand human behavior, too.

Dogs are proving to be more than just our best friends, with a new study finding that we share proteins that could accelerate our understanding and treatment of a complication of anterior cruciate ligament (ACL) injury, which affects both species.

Excavations found that the brain of what seems to be a human male contained dark glass formed during the eruption of Mount Vesuvius in 79 CE. The effect can't be explained by lava temperatures alone, but rather a different event from the cataclysm.

We know what they look like, and even sound like, but there’s one question you might not have pondered: what do ancient Egyptian mummies smell like? Whether you wanted to know or not, scientists have now given us an answer.

A new discovery in Kenya shows that ancient human relatives crossed paths – literally. Paleontologists have discovered the first known example of fossil footprints left by two different species of ancient hominins on the same day.

The hugely ambitious project of mapping the estimated 37.2 trillion cells of the human body is close to reaching a historic milestone – the first draft of the 'atlas.' We got a glimpse at what's in store from this unprecedented biological guidebook.

Most of us do it, in one form or another, but how and when humans began to kiss is still hotly debated among researchers. Now, a new evolutionary theory has been put forward, which says the origins of the kiss may date back millions of years.

At the time of writing, there were an estimated 8,123,518,311 living humans on Earth – roughly the most there has ever been. But as fertility and birth rates continue to freefall, the numerical peak of humanity is quickly approaching.

Well-preserved bones of a two-tonne glyptodont revealed cut marks indicative of stone tools, suggesting that human hunter-gatherers had settled in the Americas around 21,000 years ago – some 5,000 years before people were thought to have arrived.

Harvard and Google Research have mapped thousands of cells and millions of synapses in a poppy seed-sized sample of tissue. The result is a set of truly stunning images and marks a major step towards understanding of the biggest challenges in science.
