Geology and Genes: The Geography of Life

S1 E5: Trace the importance of geology in Darwin’s thinking and his many observations that make sense only in light of the theory of plate tectonics, which was not developed until the 1960s. Chart the breakup, movement, and reassembly of continental plates that dispersed related flora and fauna all over the planet. Also look at the Wallace Line in Indonesia, which separates Asian from Australian species.
