Ramirez … WitrynaThis trait is a result of a mutation from thousands of years ago. The mutation causing the trait was beneficial and heritable, so it spread throughout the human population and many of us today have this trait! There are 4 mechanisms of evolution (how evolution happens): natural selection. mutation. genetic drift, and.
WitrynaNatural selection can cause a trait variation to become more or less common in a population over time. Natural selection requires variability, heritability, and … Witryna17 lip 2024 · If natural selection favors an average phenotype, selecting against extreme variation, the population will undergo stabilizing selection (Figure 1a). In a population of mice that live in the woods, for example, natural selection is likely to favor individuals that best blend in with the forest floor and are less likely to be spotted by …
