What is the term for the synthesis of Darwinian natural selection with the principles of population genetics?
Answer:
Neo-Darwinism
Neo-Darwinism, also known as the Modern Synthesis, integrates Charles Darwin's theory of natural selection with Mendelian genetics and population genetics. This synthesis explains how genetic variation within populations provides the raw material upon which natural selection acts to drive evolutionary change over time.
