Researchers examined the plant life in the China's Hengduan Mountains, the Himalaya Mountains, and the Qinghai-Tibet Plateau. Using DNA to build family trees of species, they learned that the diversity of plants in that region today can be traced back to newly-formed mountain ranges 30 million years ago, and monsoons that came later. It's a concrete example of how climatic and environmental changes influence life on Earth.
