mechanisms of evolution

Evolutionary mechanisms encompass various processes that influence the genetic makeup of populations over time. Natural selection, a key driver, results in observable changes in allele frequencies, often favoring traits that enhance survival and reproduction.

sexual selectoin

a special type of natural selection

gene drift

is a change in the frequency of an allele within a population over time
bottleneck effect

is the loss of genetic variation that occurs when a new population is a very small number of individuals from a larger population.
