How does evolution occurs? |
| Answer» Natural selection and sexual selection.Explanation:I\'m sure this has been answered in detail, so basically:Evolution is the change of the frequency of alleles over time.Natural selection: Some cause--environmental, predation, chemical, competition, resource change, etc--leads to a change in a population, however large or small. The longer this occurs, the more noticeable the change and the greater the possibility of creating new species.Sexual selection: females prefer males with certain characteristics, or certain characteristics help males compete with other males for mates (sometimes *** rolls are reversed). Since these characteristics increase reproduction, they will be inherited by young that will also have more reproductive success. And, the population will change over time. | |
