The evolutionary advantage of having eyebrows

Eyebrows—we all have them, but what are they actually for? While eyebrows help to prevent debris, sweat, and water from falling into the eye socket, they serve another important function too – and it's all to do with ...

Modern humans interbred with Denisovans twice in history

Modern humans co-existed and interbred not only with Neanderthals, but also with another species of archaic humans, the mysterious Denisovans. While developing a new genome-analysis method for comparing whole genomes between ...

Ancient hominid 'hanky panky' also influenced spread of STIs

With recent studies proving that almost everyone has a little bit of Neanderthal DNA in them——up to 5 percent of the human genome—- it's become clear our ancestors not only had some serious hominid 'hanky panky' going ...

Hominins may have been food for carnivores 500,000 years ago

Tooth-marks on a 500,000-year-old hominin femur bone found in a Moroccan cave indicate that it was consumed by large carnivores, likely hyenas, according to a study published April 27, 2016 in the open-access journal PLOS ...

A world map of Neanderthal and Denisovan ancestry in modern humans

Most non-Africans possess at least a little bit Neanderthal DNA. But a new map of archaic ancestry—published March 28 in Current Biology—suggests that many bloodlines around the world, particularly of South Asian descent, ...

Stone-age tools found, but who wielded them?

Scientists have discovered stone-age tools at least 118,000-years-old on an Indonesian island but no trace of the early humans that made them, according to a study released Wednesday.

Neanderthal genes gave modern humans an immunity boost, allergies

When modern humans met Neanderthals in Europe and the two species began interbreeding many thousands of years ago, the exchange left humans with gene variations that have increased the ability of those who carry them to ward ...
