How does genetic variation and environmental factors affect evolution by natural selection?
de
What are the four steps of Darwin's theory of evolution by natural selection and examples?
Overproduction, variation, selection, and adaptation
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.
Is natural selection the only force that drives biological evolution?
No. Natural selection requires reproductive variation to work on. Besides reproductive variation and natural selection, there are various forces, biochemical as well as population dynamical, that affect the allelic composition of a population.
Evolution by natural selection involves what three factors?
there is variation in traits , differential reproduction and last is heredity
Why are chimpanzees brown and black?
evolution. variation and natural selection. DNA!!!!
How does natural selection and variation help cause evolution?
because the rocks are pretty

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.
