Evolution is
|
|
a change in the allele frequencies of a population over time.
|
|
|
a change in the allele frequencies of an individual over time.
|
|
|
the gene pool.
|

|
a result of the Hardy-Weinberg principle.

Explanation:
Detailed explanation-1: -Evolution reflects the adaptations of organisms to their changing environments and can result in altered genes, novel traits, and new species. Evolutionary processes depend on both changes in genetic variability and changes in allele frequencies over time. The study of evolution can be performed on different scales.
Detailed explanation-2: -Formally, evolution is a change in allele frequencies in a population over time, so a population in Hardy-Weinberg equilibrium is not evolving.
Detailed explanation-3: -The change in allele frequency over time is called microevolution. Microevolution and the change in allele frequency occurs to to mutation, gene flow, genetic drift or selection.
