Jerry Coyne's Report

Due to the wide variety of plants and animals throughout the world, and their similarities and differences is what proves evolution, according to Chapter 4: The Geography of Life, the biogeography can only be explained by evolution of all the, “diversity of life on continents and islands,” (Coyne, 2009, p. 109). Even though, this idea of evolution is different than previous chapters; must be remembered, that Jerry Coyne is explaining the whole theory, so they are all connected and part of the whole theory. In detail, Coyne explains the evidence associated with different plants and animals around the world, by using biogeography to study the continents, and island, for evidence of a wide variety of different animals that evolved accordingly. To begin with, many factors influence the variety of species in the world, and Jerry Coyne uses the effects of continental drift and the geography as evidence for evolution. Ultimately, Jerry Coyne compares those animals that are …show more content…
For example, the two versions of islands, continental islands once connected to a continent, and oceanic island are those island that never connected continental land. Therefore, Jerry Coyne analyzes how many of the oceanic islands were, “lacking the native freshwater fish, amphibians, reptiles, and land mammals,” at many of these oceanic islands. Furthermore, is the effect when introducing non-native animals to these oceanic islands, because many of those animals over-run the island. Hawaii is a very good example of this, because of the introduction of pigs, now all over the island are herds of wild pigs in the woods. In fact, another comparison between those animals native to continental island and oceanic island is their ability to reach these island, for example, a bird has the ability to reach an oceanic island and spread the food source from previous
