A new analysis of more than 2,500 human genomes indicates that modern Eurasians who acquired Neanderthal DNA during past interbreeding migrated back to Africa and spread those sequences.

The Scientist’s reporters tracked the development of CAR T cell therapies, explored the Neanderthal DNA in our genomes, and dove into a CRISPR controversy.

Researchers’ simulations suggest that small population sizes and inbreeding made Neanderthal populations vulnerable to chance fluctuations in population size.

A discovery of Neanderthal footprints reveals insights into the hominin’s social structure.

Fossil records show that the most recent shared ancestor with modern humans may have lived at least 800,000 years ago.

A mandible dating to 160,000 years ago is the first evidence of Denisovan hominins outside the Russian cave where they were first discovered in 2010.

Denisovans and Neanderthals likely overlapped at this Stone Age hot spot for thousands of years, and modern Homo sapiens may have dwelled there, too.  

The findings of a new study contradict previous results from some of the same scientists that suggested Neanderthal DNA was gradually removed from modern human genomes.

Modern humans retain DNA sequences from Neanderthals related to fighting off RNA-based viruses.
