By creating the most complete maps to date of all the changes happening thousands of years ago… researchers showed that the extinction didn't line up with any single change but with the combination of several new pressures on woolly mammoths…"It's not just the climate change that killed them off," MacDonald said. "It's the habitat change and human pressure. Hunting expanded at the same time that the habitat became less amenable."….
