Ghost lineages reveal themselves through ancient genes that still exist in living beings today.

Did modern humans erase Neanderthals, or did our close cousins fade away for reasons that had little to do with us? A pair of major papers in Science and Nature on Dec. 12, 2024, sharpen that question ...

The Indigenous peoples of the Bolivian highlands are survivors. For thousands of years they have lived at altitudes of more than two miles, where oxygen is about 35 percent lower than at sea level.

The human genome is made up of 23 pairs of chromosomes, the biological blueprints that make humans … well, human. But it turns out that some of our DNA — about 8% — are the remnants of ancient viruses ...

Knowing how human DNA changes over generations is essential to estimating genetic disease risks and understanding how we evolved. But some of the most changeable regions of our DNA have been ...

To identify possible burn-injury response genes, researchers examined the transcriptomes (the genes expressed) in both burnt and unburnt skin from humans and rats. Examining the gene sequences, they ...

Human evolution’s biggest mystery, which emerged 15 years ago from a 60,000-year-old pinkie finger bone, finally started to unravel in 2025. Analysis of DNA extracted from the fossil electrified the ...

“Burns are a uniquely human injury. No other species lives alongside high temperatures and the regular risk of burning in the way humans do,” study co-author Joshua Cuddihy of Imperial’s Department of ...

Regular contact with fire could play a key role in the formation of the human genome, affecting the mechanisms of healing and immune response. This is the conclusion reached by scientists at Imperial ...

If we look across the whole of the mammal branch of the tree of life, we find there are many groups of mammals that have ...
