Khan Academy: Mechanisms of Evolution
When a population is in Hardy-Weinberg equilibrium, it is not evolving. Learn how violations of Hardy-Weinberg assumptions lead to evolution.

Biology Wise: Examples That Explain Geographic Isolation
Discusses how unique species evolve when geographic barriers restrict population interbreeding, such as when organisms are confined to an island. Examples are provided.
BiologyWise
Biology Wise: Temporal Isolation: Definition and Examples
Discusses how unique species evolve when temporal barriers prevent population interbreeding. This happens when two closely related species have different cycles of reproductive maturation and the times when they are fertile do no align....

Biology Wise: Crossing Over and Why Is It Important in Meiosis?
Explains what meiosis is and what happens during crossing over where genetic material is exchanged between chromosomes. This process is important for ensuring that there is lots of genetic variation in a population as it improves survival.
