"We know from today's species that they move up and down mountains in accordance with climate change," said Adrian Lister, a professor in the Department of Paleontology at The Natural History Museum in London. Lister added that "many are now moving upwards" in an attempt "to escape global warming. It seems perfectly reasonable that a similar thing could have happened over longer time scales in the past."
Anthony Barnosky, a professor in the Department of Integrative Biology at UC Berkeley and a curator at the university's Museum of Paleontology, said the study demonstrates "the importance of isolated areas as cradles of evolution."
Wang and his team are already planning future studies in Tibet, where they "have barely scratched the surface."
"Cold places such as Tibet, the Arctic and Antarctic are where the most unexpected discoveries will be made in the future," Wang predicts. "These are the remaining frontiers that are still largely unexplored."
