Definitions:

Punctuated Equilibrium

Model of evolutionary change in a species which suggests that there are long periods of little or no change, followed by brief periods of rapid speciation.

Phyletic Gradualism

Phyletic gradualism is an evolutionary model suggesting that species evolve through a gradual change of populations over long periods of time.

Speciation

The evolutionary process by which new biological species arise.

Isolating Mechanisms

Biological features or behaviors that prevent species from interbreeding, thus maintaining species boundaries and genetic integrity.
