Document Summary

We have a reliable method for determining the age of rocks and fossils. The data does not support the hypothesis of divine creation of a. Alfred russel wallace became fascinated with the distribution of animals, and agreed. Developed evidence from biogeography (study of the distributions of organisms) Fossil armadillos and living armadillos were in the same area of the world and did not distribute in different places. Suggested that glyptodonts were the ancestors of current day armadillos (evolution occured) Individuals living close to one another in a given species more closely resembled each other than individuals living at a distance. Suggested that organisms close together are more closely related than further away seemed the answer) Further, that this variation if great enough would produce new species (evolution. Wallace 1876 book the geographical distribution of animals. Active immigration:under their own power (walking, swimming, flying) Passive immigration carried by water,air, or land movement.
