Question

biological evolution refers to _.
○ descent from monkey ancestors
○ biological and cultural changes that lead to increase in efficiency
○ changes in the genetic makeup of a population over generations
○ gradual improvement and progression in a species
○ progressive elaboration and increase in complexity

Explanation:

Biological evolution is the change in the genetic makeup of a population over successive generations through mechanisms like mutation, natural selection, genetic drift, and gene - flow. It is not just about descent from a particular ancestor like monkeys, nor is it a simple progressive increase in complexity or a combination of biological and cultural changes. It focuses on genetic changes in populations.

Answer:

changes in the genetic makeup of a population over generations
