Bio 3.5 ,, Patterns + Rates

Convergent evolution

The evolution of similar phenotypes/analogous structures despite having no recent common ancestor/by species from different lineages due to them sharing a similar niche. (Pattern)

Analogous structures

Superficially similar features that have evolved independently in unrelated species due to similar selection pressures in different areas. (Pattern)

Divergent evolution

The diversification of a common ancestral species into two or more species, they will share homologous structures/phenotypes. (Pattern)

Homologous structures

Features similar in structure and origin but different in function. The similarity in structure indicates common ancestry, while differences in function indicate adaptation to different selection pressures in different environments. (Pattern)

Adaptive radiation

The rapid diversification of related species from a single ancestor, to exploit unoccupied niches. (Pattern)

Co-evolution

Where the species exert selection pressures on each other, or one species exerts a selection pressure on another over time. (name selection pressure for another A point) (Pattern)

Punctuated Equilibrium

long periods of stasis followed by rapid periods of change. (Rates)

Gradualism

The process of slow small periodic changes in the gene pool over long periods of time. (Rates)
