‘A History of Contact’: Geneticists Rewrite the Story of Neanderthals and Other Early Humans

Detection of modern human-to-Neanderthal gene flow (H→N) and its consequences. Modern human-to-Neanderthal admixture causes a local increase in heterozygosity in the Neanderthal genome, a feature that enabled approaches to quantify and detect introgressed sequences. We used modern human-introgressed sequences in the Neanderthal genome to refine estimates of Neanderthal ancestry in contemporary humans by decomposing IBDmix-detected … Read more

Early humans left Africa much earlier than previously thought

Hundreds of thousands of years ago, our species emerged in Africa. Research into the DNA of living humans has shown that early Homo sapiens remained on the continent for a long time, with a small group leaving only 50,000 years ago to populate the rest of the world. However, these findings raise a puzzling question: … Read more

These ants perform life-saving surgeries on injured nestmates, similar to humans

Last year, one species of ant was caught using antibiotics. Now, another species has been spotted performing amputations. Researchers have recently confirmed experimentally that this operation and the other treatments ants give each other do indeed save ants’ lives. We’ve known for a few years that ants treat each other’s wounds, but we’re only just … Read more

Humans are to blame for the extinction of megafauna, new research finds

Once upon a time, there were many giants living in our world. Actually, it wasn’t that long ago. Once the dinosaurs had had their day, our planet was home to a whole new range of gigantic animals, from human-sized sloths to woolly mammoths to enormous wombats and kangaroos to the magnificent giant goose. Between about … Read more
