Last year, they changed their tune—and now it looks like DNA passed down from Neanderthals has had a “profound impact” on our immune systems. Scientists compared a section of the modern human genome to the same area in the genomes of Neanderthals and another ancient hominid, the Denisovans, the Los Angeles Times reports. More»
