The three major mechanisms of evolution differ in how they work, and as a result often have different effects on a population. Review your understanding of natural selection, genetic drift, and gene flow by sorting the statements below into the correct bins. Drag each statement into the appropriate bin depending on whether it applies to natural selection, genetic drift, or gene flow.

Natural Selection

Consistently causes a population to become better adapted to its environment

A result of differential success in reproduction

Cannot cause a harmful allele to become more common

Genetic Drift

Responsible for the founder effect

Responsible for the bottleneck effect

Causes allele frequencies to fluctuate randomly

Gene flow

Can introduce new alleles into a population's gene pool

A result of the movement of fertile individuals or their gametes

Explanation:

From the above the mechanisms of evolution have each been matched to their definitions and characteristics. Notable is natural selection which is the central concept of evolution whereby organisms become better adapted to their environment with more tendency to survive and produce offspring who continue in this manner. It stems from the theory of evolution by Charles Darwin, and now regarded as the main process that brings about evolution
