Darwin 2.0: New theory on speciation, diversity

It has long been thought that dramatic changes in a landscape like the formation of the Andes Mountain range or the Amazon River is the main driver that initiates species to diverge. However, a recent study shows that speciation occurred much later than these dramatic geographical changes. Researchers have found that time and a species' ability to move play greater parts in the process of speciation.
