By sequencing the genomes of dozens of people who lived between 120,000 and 20,000 years ago, researchers found that Neanderthals had a rare blood group that could have been fatal to their newborns.

If Neanderthal women mated with Homo sapiens or Denisovan men, there was a high risk of newborns having neonatal hemolytic disease. Blood incompatibility with Homo sapiens may have led to ...

“Blood group systems were not known in Neanderthals and Denisovans,” Condemi says. Blood analysis is a unique tool, albeit one that needs a larger dataset of ancient genes to reach its full ...

The lack of variety in blood type within Neanderthals may have led them to their demise. While H. sapiens had wider diversity in blood types, which may have given them the immune system arsenal ...

A group of scientists has found clues in blood groups that explain how modern humans managed to survive and expand from Africa to the rest of the world. Published in the journal Scientific Reports, ...

When modern humans journeyed out of Africa, a rapid evolution in their red blood cells may have helped them survive — but it may have also led to the eventual disappearance of Neanderthals, a new ...

Sometime between 135,000-50,000 years ago, hands slick with animal blood carried more than 35 huge horned heads into a small, ... Neanderthals carried slightly different versions of these genes.

The Neanderthal to whom the tooth belonged was probably a carnivore. Other chemical tracers indicate that this individual did not consume the blood of their prey, but ate the bone marrow without ...
