He discussed all of the factors then known to influence the current and past geographic distribution of animals within each geographic region. These factors included the effects of the appearance and disappearance of land bridges (such as the one currently connecting North and South America) and the effects of periods of increased glaciation. He provided maps showing factors, such as elevation of mountains, depths of oceans, and the character of regional vegetation, that affected the distribution of animals.
