How does environmental pressure affect natural selection?
Garfield Gislason
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.

Which does natural selection affect populations or individuals?
Populations evolve, but individuals are selected. Natural selection affects individual organisms.
How does natural variation affect evolution?
Natural selection (the driving force of evolution) is the selection of genetic variations by how they effect the organism's chances of survival or reproduction. If they diminish it's chances, the organism or it's immediate offspring die and the gene is gone. If the genetic variations increase it's chances, then it survives. Without genetic variations there can be no evolution. Natural selection is the selection (by environmental pressures) of those variations.
What do you by environmental advocacy?
Ivestigate sounces of environmental abuse and the affect it has had or will have on people.
What various environmental factors that could affect the selection process?
Environmental factors can determine the costs of running some businesses and affect the public's perception of a business. Companies need to minimize their pollution to avoid negative publicity.
How does natural selection affect variation?
Variation naturally occurs in populations as new traits arise from random mutations. However, through natural selection only those traits that are beneficial to the organism are passed on to the next generation. Any harmful mutations are naturally weeded out.

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.
How does selection affect natural selection?
Organisms are affected by Natural Selection because Inherited characteristics affected the likelihood of an organism's survival and reproduction.
Which does natural Which does natural selection affect?
natural selection is basiclly only the strong survive which means it effects the weak by killing them but bernifits the strong
How could natural selection affect the songs that birds sing?
Through ongoing natural selection a population adapts to its enviroment
How does natural selection affect survival?
Natural selection is the process which determines the shark's evolution. It is humankind that is threatening the sharks' survival.
Which does natural selection affect populations or individuals?
Populations evolve, but individuals are selected. Natural selection affects individual organisms.
Does natural selection affect individuals populations or both?
Both
Does natural selection affect the survival of an individual or a species?
species
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.
How do humans affect artificial selection?
Humans directly affect artificial selection. They do this by selecting the specific traits that they prefer which they cannot don in a natural selection.
