Phyletic Gradualism
Phyletic gradualism is an evolutionary model proposing that species evolve through gradual changes of traits over long periods of time.
Punctuated Equilibrium
A theory in evolutionary biology that suggests species evolve rapidly during short periods of time followed by long periods of stasis.
Speciation

Reproductive Isolating Mechanism
Biological features of organisms that prevent species from interbreeding and producing fertile offspring.
