Plant diversification and mountain uplift

A study of China’s Hengduan Mountains finds that over the past 8 million years, as the mountains were tectonically uplifted, the rate at which resident plants evolved into new species was higher than in adjacent, older mountains, supporting the hypothesis that uplift creates environmental conditions favoring the origin of new species and potentially explaining how mountains came to be biodiversity hotspots, according to the authors. - Read at PNAS
