Divergent evolution
Convergent evolution
Mimicry
Camouflage
Homologous structures
Analogous structures
Structures with the same function found in animals that have a different common ancestor
Caused by random events that remove genes from a population
Theory that living things come from other living things
Structures found in organisms with common evolutionary ancestry
Adaptation in which one animal resembles another
Scientist who proposed the idea of evolution by natural selection
This is an adaptation that aids in the survival of an organism
Change in populations over time
Type of evolution in which species evolve to be different even though they have a common ancestor
Breeding an organism with specific traits
Evolution is not occurring because the frequency of alleles stays the same over generations
Adaptation that allows an animal to blend in with its surroundings
Type of evolution in which a species evolves to be similar, no common ancestor
