But we’re almost certainly absolved of guilt in the case of the woolly mammoth, according to an international team of scientists who spent the past 10 years sifting through traces of mammoth urine, feces, and skin cells in the ground to figure out what truly caused the species’ extinction.

Though a holdout population of mammoths survived on Russia’s Wrangel Island until about 4,000 years ago, around the same time Stonehenge was nearing completion, all other mammoths were long gone by then.

Though the team determined that the Arctic once had a fair spread of vegetation—great news for all of the aforesaid species—the onset of a warmer, wetter climate meant that vegetation disappeared, a disappearance coincident with mammoth extinction.

Last month, a start-up called Colossal said it has a goal of bringing a woolly mammoth calf to bear within six years using DNA technology
