Speciation Pt. 2

Review Speciation- the formation of new and distinct species in the course of evolution. Convergent vs Divergent Evolution

Review Analogous v Homologous Structures

Speciation (New) Allopatric Speciation - results when a population is separated by a physical barrier and evolve separately; isolated

Speciation Sympatric Speciation – evolution occurs without physical separation of members of the population.

Vestigial Structures have no obvious function and were used by a past ancestor
