Analogous: having characteristics that are similar because of convergent evolution, not homology. Artificial selection: the selective breeding of domesticated plants and animals to encourage the occurrence of desirable traits. Biogeography: the study of the past and present geographic distribution of species. Catastrophism: the principle that events in the past occurred suddenly and were caused by different mechanisms than those operating today. Convergent evolution: the evolution of similar features in independent evolutionary lineages. Fossil: a preserved remnant or impression of an organism that lived in the past. Homology: similarity in characteristics resulting from a shared ancestry. Homologous structures: structures in different species that are similar because of common ancestry. Natural selection: a process in which individuals that have certain inherited traits tend to survive and reproduce at higher rates than other individuals because of those traits.
