Briana Pobiner, a research scientist and museum educator at the Smithsonian National Museum of Natural History’s Human Origins Program, said it was “mind-blowing” to find footprints of not just one but two species walking in the same area. While it’s the first time that footprints have suggested hominins of two species directly encountered one another, genetic evidence has revealed that Neanderthals interbred with Homo sapiens and Denisovans, a little understood hominin only known from a scant few fossils. “It’s impossible to go back in time to actually observe these species 1.5 million years ago — but having both of their footprints on the same surface?
