This term represents the integration of these two fields that occurred in the mid-20th century, solidifying our understanding of evolution. Here's a breakdown:
* Darwinian evolution theory focuses on the idea that organisms evolve through natural selection, where traits that increase survival and reproduction become more common in a population over time.
* Population genetics studies the genetic makeup of populations and how it changes over generations.
The Modern Synthesis combined these two fields by:
* Explaining the mechanisms of evolution at the genetic level: It showed how natural selection operates on genetic variation within populations.
* Demonstrating how populations evolve over time: It incorporated mathematical models to explain how genetic changes accumulate and lead to significant evolutionary changes.
This synthesis provided a comprehensive framework for understanding evolution, which is still considered the foundation for modern evolutionary biology.
