An encounter with a mysterious and extinct human relative – the Denisovans – has left a mark on the immune traits of modern Papuans, in particular those living on New Guinea Island. This is a new discovery we describe in a study published in PLoS Genetics today. It further suggests that our modern human diversity didn’t just evolve – some parts of it we got from other, extinct human groups.
