Long time = evolution. Short time = mutation.
Evolution is the change in allele frequency over time in a population of organisms.
Changes that are genetic
Evolution.
That is the definition of evolution.

Yes. Without variation in organisms for natural selection to choose from there would be no change in allele frequency over time in the population of organisms under discussion. This is the definition of evolution, so without change over time, no evolution.
The term used to describe the generation-to-generation change in allele frequencies of a population is simply evolution. Simple answer for a complicated-looking question. ;) Hope this helps.
Evolution; the change in allele frequencies over time in a population of organisms.
A genetic drift is a random change in allele frequency over time that is brought about by chances. A bottle neck is a drastic reduction in population size brought about by severe pressure.
Any change over time in the relative frequency of alleles in a population.
Evolution is the change in allele frequency over time in a population of organisms. By mutation, genetic drift, gene flow and natural selection.
Evolution is change over time in a population of organisms. Formal and impressive to teacher definition is this; ' Evolution is the change in allele frequency over time in a population of organisms. '
