Natural selection doesn't reduce variation. Variation is regulated by the rate of mutation.
Natural selection reduces the chance of bad variation from being passed on and increases the chances for good variation to be passed on.
Mutations are important for evolution because they provide the variability whereupon natural selection acts.true last answered by zaporia

natural selection
Natural selection directly works on the heritable traits of organisms that impact their ability to survive and reproduce in a given environment. Organisms with traits that enhance their survival and reproductive success are more likely to pass those traits on to the next generation.
Natural selection is a key mechanism of evolution that drives the adaptation of organisms to their environments, shaping the biodiversity within biomes. By favoring individuals with advantageous traits that enhance survival and reproduction, natural selection enables species to thrive under specific ecological conditions. This process not only influences the characteristics of organisms but also impacts the dynamics and stability of entire ecosystems, as species interact with one another and their environment. Ultimately, natural selection helps maintain the balance of life across various biomes.
Natural selection 'weeds out' defective genes through successive generations - this both enhances a species chances of survival, and reduces variations in the species genetic make-up.

yes.
We call this speciation, and is largely driven by evolution and natural selection.
Because there is variation within a species, it is therefore possible for the law of natural selection to operate, by selecting those variations which best enhance survival and reproduction.
Natural variation in artificial selection is used because humans choose from among the naturally occurring variation s in species. Natural selection is related to species fitness because Darwin called natural selection survival of the fittest because those that could survive would carry their species on there for being the naturally selected.
The book "On the Origin of Species by Means of Natural Selection" was written by Charles Darwin.
Natural selection and sexual selection are both mechanisms of evolution, but they differ in how they shape species. Natural selection acts on traits that affect an organism's survival and ability to reproduce in its environment, leading to adaptations that increase survival and reproduction. Sexual selection, on the other hand, acts on traits that affect an organism's ability to attract mates and reproduce, leading to the development of traits that enhance mating success. In summary, natural selection primarily influences survival and reproductive success in the environment, while sexual selection primarily influences mating success and reproductive opportunities.

how natural selection help some species to survive and few got extinct
Natural selection usually causes a species to change gradually
