Modern synthesis

Definition

Modern synthesis is the fusion of Mendelian genetics with Darwinian evolution that resulted in a unified theory of evolution. It emphasizes the role of natural selection, genetic variation, and population genetics.

5 Must Know Facts For Your Next Test

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