Gene Flow versus Natural Selection
Lecture no. 4 from the course: What Darwin Didn’t Know: The Modern Science of Evolution
Taught by Professor Scott Solomon | 30 min | Categories: The Great Courses Plus Online Science Course
Natural selection is not the only mechanism driving evolution. In this lecture, discover how the movement of individuals leads to gene flow between populations. Travel to the Galapagos Islands and neighboring Cocos Island to see how finches evolved into multiple species in the Galapagos archipelago but stayed a distinct species on isolated Cocos. Consider the implications for human evolution.
