Modern synthesis integrates natural selection with genetic inheritance.
It was developed in the early 20th century by scientists like Ronald Fisher and J.B.S. Haldane.
Gene flow, genetic drift, mutation, and natural selection are key mechanisms within modern synthesis.
It explains how small genetic changes can lead to significant evolutionary shifts over time.
Modern synthesis provides a mathematical framework for understanding population genetics.
