<i>Homo neanderthalensis</i> (IMAGE) University at Buffalo Caption A reconstruction of Homo neanderthalensis, as created by artist John Gurche for the Smithsonian's National Museum of Natural History. A study led by University at Buffalo biologist Omer Gokcumen compared the DNA of modern humans to Neanderthals and Denisovans (another ancient hominin). The research found that genetic deletions associated with various aspects of human health, including psoriasis and Crohn's disease, likely originated in a common ancestor of the three species.
