Detailed explanation-1: -Evolution is defined as the change in the inherited traits of a population of organisms through successive generations. When living organisms reproduce, they pass on to their progeny a collection of traits.

Detailed explanation-2: -Evolution is the process by which populations of organisms change over generations. Genetic variations underlie these changes.

Detailed explanation-3: -When a population interbreeds, nonrandom mating can sometimes occur because one organism chooses to mate with another based on certain traits. In this case, individuals in the population make specific behavioral choices, and these choices shape the genetic combinations that appear in successive generations.

Detailed explanation-4: -Genetic drift is the change in allele frequencies in a population over time due to random sampling events (e.g., differences among individuals in survival or fecundity that are unrelated to their phenotype/genotype).
