What is the only evolutionary mechanism that consistently leads to adaptive evolution?
Natural selectionBecause natural selection has a "sorting" effect, it consistently increases the frequency of alleles that improve the match between an organism and its environment.
Is natural selection fast or slow process?
Evolution is the observed effect of natural selection acting on reproductive variation. Natural selection is a continuous process. The rate at which natural selection changes allele frequencies depends on the effect of the allele in the world. If the allele considered provides a significant reproductive benefit when compared to rival alleles, it will spread throughout the population gene pool much faster than the rival alleles.
What happens to unnecessary traits during the process of natural selection?
How does natural selection affect undesirable traits?
How do mutations relate to natural selection?
Mutation, a copying error in the replication of DNA, can give rise to variation in an organisms phenotype and if this new phenotype is beneficial to survival and reproductive success ( as little as 1% ) it will be selected naturally against the immediate environment, then if this so selected organism leave many descendents with the same beneficial traits then the populations gene pool will change in allele frequency and you have evolution. ( a 19th century sentence Darwin would be proud of! )
What are three ways natural selection can effect the polygenic traits?

How does nonrandom mating affect evolution?
Non-random mating is otherwise known as sexual selection. Some see this as distinct from natural selection, but I think that sexual selection is merely a form of, or perhaps more a complication of natural selection. Selection, natural or sexual, is the effect that "guides" evolution, that allows evolution to produce populations suited to their environment.
Was Charles Darwin contribution natural science?
Charles Darwin gave the theory of evolution. He he examined earthworms and their effect on soil, he examined human evolution and sexual selection.
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 is one effect of natural selection?
Natural selection helps to increase biodiversity and the number of new species.
What is the effect of climate on the size of the finch's beak an example of?
Natural Selection. Bedi<3;)
How does adaptation effect natural selection and an organisms for survival?
Theo is the solution
What happens to unnecessary traits during the process of natural selection?
How does natural selection affect undesirable traits?
A random change in a population's allele frequency?
Evolution is the change in allele frequency over time in a population of organisms. By mutation, genetic drift, gene flow and natural selection.

What effect would natural selection have on a partially evolved bat?
it would die
