Study Suggests Weather and Not Hunting Killed Off Wooly Mammoths
Big Hairy Ian writes, quoting the BBC: "A DNA analysis shows that the number of creatures began to decrease much earlier than previously thought as the world's climate changed. It also shows that there was a distinct population of mammoth in Europe that died out around 30,000 years ago. ... Dr Dalen worked with researchers in London to analyse DNA samples from 300 specimens from woolly mammoths collected by themselves and other groups in earlier studies ... [The researchers] speculate that it was so cold that the grass on which they fed became scarce. The decline was spurred on as the Ice Age ended, possibly because the grassland on which the creatures thrived was replaced by forests in the south and tundra in the north."
Or you know, the scientific method was used that refines theories, based on new evidence.
Maybe we should be like you, where we know that there's no human-induced climate change because we ignore the unprecedented rate of change in temperature over the past 2 centuries, and keep all our understanding exactly the same as when we were born.
