Evolution by natural selection actually relies on variation within a population. Without variation, there would be no genetic differences for natural selection to act upon, leading to no evolution. Variation provides the raw material for natural selection to work with, allowing beneficial traits to be favored and passed on to future generations.

Why is genetic variation important for natural selection to drive evolution?
Genetic variation is important for natural selection to drive evolution because it provides the raw material for natural selection to act upon. Without genetic variation, there would be no diversity in traits for natural selection to favor or eliminate, and evolution would not be possible.
Does natural selection require genetic variation in order to drive the process of evolution?
Yes, natural selection requires genetic variation to drive the process of evolution. Genetic variation provides the raw material for natural selection to act upon, leading to changes in the traits of a population over time.
Why does evolution evolution by natural selection can not occur if the variation in a characteristic does not contribute to differences in fitness?
Differential selection is just that, differential. Some variation is marginally superior to another variation us fitness difference, so the key is to have variation. Then natural selection will " see " this slight variation and select the better adapted trait against the background of the immediate environment.
What 2 factors determine the evolution of a species?
Two key factors that determine the evolution of a species are genetic variation and natural selection. Genetic variation provides the raw material for evolutionary change, while natural selection acts on this variation by favoring individuals with traits that increase their chances of survival and reproduction.
Which is not part of darwins theory of natuarl selsction?
The idea that evolution is a directed process with a predetermined goal or purpose is not part of Darwin's theory of natural selection. Instead, Darwin proposed that evolution occurs through random variation and selection based on the fitness of individuals in a given environment.
Why is genetic variation important for natural selection to drive evolution?
Genetic variation is important for natural selection to drive evolution because it provides the raw material for natural selection to act upon. Without genetic variation, there would be no diversity in traits for natural selection to favor or eliminate, and evolution would not be possible.

Is natural selection a process or a result of a process?
Natural selection is only the result of changing environments, mutation and the variation resulting therein. Natural selection is the process of adaptive change and the main mechanism of evolution that leads to speciation. Natural selection is a process as mutation and variation are grist to the mill of natural selection.
What has the author Jeffry B Mitton written?
Jeffry B. Mitton has written: 'Selection in natural populations' -- subject(s): Enzymes, Evolution, Natural selection, Molecular evolution, Variation (Biology)
In order for evolution by natural selection to occur what has to happen?
There must be genetic variation, the variation must be heritable, and there must be differential reproduction (due to competition).
What is Darwinian evolution?
Darwinian evolution is descent with modification and natural selection, or, in other terms, reproductive variation and differential reproductive success.
