Science | March 2019. The Fishy Mystery of Lake Malawi. In the second-largest lake in Africa, fish evolution is taking place at an explosive rate. Why? Scientists are diving into the question This ultimately supports a fish-mammal evolution, as implied by the title of Shubin's work. Shubin proceeds to support evolution by comparing characteristics of humans with that of phylogenetically older species. Embryology provides evidence for Shubin. All animals with skulls share something developmentally.
