Q: In chapter 9 Dawkins discusses how geographical barriers crate species and also explains why we see certain similarity’s and differences between continents?
In chapter 9 Dawkins expands on the idea of “islands first introduced in chapter 2 and show how in relates to the evolution of organisms. “Islands” refers to the isolation of one breeding population of a species form another; the isolation can be caused by many factors from geographic barriers to intense selection pressers. These barriers prevent gene flow from one population to the next, and this allows those populations to diverge from one another eventually crating new species. When the continents moved due to continental drift the caused geographic barrier to spring up between populations,
