When nothing happens to exert strong population pressure on that population, natural selection favors the allele frequency already present. When mutations cause new traits, natural selection weeds these traits out because they're not as efficient as the others.

How does natural selection affect the frequency of mutatons?

Natural selection works on mutations that are already in place. The environmental changes will select for certain mutations if the selective pressure is supplied long enough for several generations of offspring to carry a higher percentage of the mutation.


What are defactors that affect the process of natural selection?

Some factors that can affect the process of natural selection include mutation rate, genetic diversity within a population, environmental changes, competition for resources, and presence of predators. These factors can influence which traits are favored or selected for in a population over time.

How does genetic variation and environmental factors affect evolution by natural selection?

Genetic variation provides the raw material for natural selection to act upon, allowing for adaptation to changing environmental conditions. Environmental factors can influence which traits are favored, leading to certain genetic variants becoming more prevalent in a population over time through natural selection. This process drives evolutionary change as individuals with advantageous traits are more likely to survive and reproduce, passing on their genes to the next generation.

What other theories are there except for natural selection?

Evolution by natural selection is currently the only viable theory explaining the diversity of life. However, the mechanism of natural selection is not the only mechanism to affect evolution. There are phenomena such as genetic drift, biased gene conversion, intragenomic conflict, and so on, that aren't exactly the same as natural selection (although they are all intertwined and all affect one another), but do affect the direction of evolution.
