Mutation: The changing of the structure of a gene

Migration: Movement from one part of something to another.

Gene flow: The transfer of genetic variation from one population to another.

Divergent Evolution: The accumulation of differences between groups which can lead to the formation of new species

Parallel Evolution:  The independent evolution of similar traits, starting from a similar ancestral condition.

Convergent Evolution:  The process whereby organisms not closely related, independently evolve similar traits as a result of having to adapt to similar environments or ecological niches.

Sexual selection: Natural selection arising through preference by one sex for certain characteristics in individuals of the other sex.

Genetic drift: Variation in the relative frequency of different genotypes in a small population.

Homologous structures:  When very different animals have bones that appear very similar in form or function and seem to be related.

Vestigial Organs:  A rudimentary structure in humans corresponding to a functional structure or organ in ancestral animals.

Ontogeny Recapitulates phylogeny: The development of an organism expresses all the intermediate forms of its ancestors throughout evolution.

Molecular Evolution:  The process of change in the sequence composition of cellular molecules such as DNA, RNA, and proteins across generations.
