FOR PENNFOSTER....
the answer is C) genetic drift
Evolution; the change in allele frequencies over time in a population of organisms.
C:Genetic drift
genetic drift
Evolution occurs at the population level, not at the level of an individual organism or a species. Changes in gene frequencies within a population over time drive the process of evolution.
evolution within a species. the allele frequencies in a gene pool of a population
A biologist who narrowly defines species based primarily on minor differences is often referred to as a "splitter." Splitting involves dividing a population into multiple species based on minor variations in characteristics.
Over one million species have been classified by Biologist.

Non-random mating means that individuals of many species have a choice about which partners to mate with. In population genetics, allele frequencies are used to depict the amount of genetic diversity in a species. There is no current research to show nonrandom mating impacts a species genetic diversity.
This is my biologist cousin, Jane. Rachel Carson was an American marine biologist and conservationist.
A population biologist studies the number(s) of species as they increase or decline in relation to their density or some environmental factor. Community ecologists study the numbers and interactions of all the species in a given location.
A species that does evolve is an open ended species. One that doesn't is the opposite of that.
