Structures that are superficially similar between organisms but arose by different evolutionary pathways (ex: bird wing and bat wing).

• Homologous Structure

• Analogous Structure

• Vestigial Structure

• Archaic Structure

The name of the scientist who proposed the theory of evolution by acquired traits.

• Charles Darwin

• Jean Baptist Lamarck

• Greggor Mendel

• Carolus Linneaus

When a population develops a different genetic makeup that is not reflective of the majority of other populations of the same species. The change is unrelated to evolution.

• Genetic Drift

• Natural Selection

• Population Bottleneck

• Founder Effect

When a very small subgroup of a population forms its own population leading to a change in the genetics of the population.

• Genetic Drift

• Natural Selection

• Population Bottleneck

• Founder Effect

The mechanism that is believed to cause evolution. Also known as survival of the fittest.

• Genetic Drift

• Natural Selection

• Population Bottleneck

• Acquired Traits
