yes.
Organisms are required for evolution to occur. Evolution is defined as something that happens when organisms reproduce.
For a mutation to affect evolution it must occur in the dominant allele. This allele is what is passed on.
The only known instance of evolution occurring is here, on Earth. Logic dictates, however, that evolution occurs wherever there is life.
Variation must exist.
For evaporation to occur you need the following: Heat (energy), and water.
Is it the elemental evolution, a chemical evolution, a nuclear evolution or a molecular evolution? Please choose one of the following.
Isolation Is necessary for speciation to occur.
yes.
Because adaptations are an observed effect of evolution. They could not happen if evolution did not occur.

Evolution occurs in population not in an individual.
Yes. Evolution ocurred in all geologic periods.
Evolution is incredibly slow because: - Changes can only occur in each successive generation - Helpful mutations occur only rarely - Situations where different adaptations are necessary are rare
You do not allow evolution to occur, for you are evolution in selective breeding.
The more variation there is in a group of specimens, the more evolution can occur between them.
