Geological uplift creates mountain biodiversity hotspots
Tuesday, April 4, 2017

Mountains tend to have more species than valleys, and new research provides support for the theory that mountain formation itself might be responsible. Yaowu Ying and Richard Ree from The Field Museum in Chicago compared regional rates of plant colonisation and speciation in the Qinghai-Tibetan p... .. read more..

The first skeletons evolved repeatedly in chalky seas
