The Oldest Neanderthal DNA of Central-Eastern Europe

September 8, 2020

Around 100,000 years ago, the climate worsened abruptly and the environment of Central-Eastern Europe shifted from forested to open steppe/taiga habitat, promoting the dispersal of wooly mammoth, wooly rhino and other cold adapted species from the Arctic.

New Algorithm Suggests That Early Humans and Related Species Interbred Early and Often

August 6, 2020

A new analysis of ancient genomes suggests that different branches of the human family tree interbred multiple times, and that some humans carry DNA from an archaic, unknown ancestor.

People Who Inherited a Special Ion Channel from Neandertals Experience More Pain

July 23, 2020

As several Neandertal genomes of high quality are now available researchers can identify genetic changes that were present in many or all Neandertals, investigate their physiological effects and look into their consequences when they occur in people today.

Breakthrough in Studying Ancient DNA From Doggerland That Separates The UK From Europe

July 18, 2020

Thousands of years ago the UK was physically joined to the rest of Europe through an area known as Doggerland. However, a marine inundation took place during the mid-holocene, separating the British landmass from the rest of Europe, which is now covered by the North Sea.

Scientists are studying Neandertal DNA in modern humans using stem cells and organoids

June 25, 2020

Protocols that allow the transformation of human induced pluripotent stem cell (iPSC) lines into organoids have changed the way scientists can study developmental processes and enable them to decipher the interplay between genes and tissue formation, particularly for organs where primary tissue is not available.
