Some organisms that share a common ancestor have features that have similar functions, and similar structures. These are known as
What mechanism of evolution increases genetic variation when animals move from one location to another
genetic drift
sexual selection
bottleneck effect
gene flow
What mechanism of evolution is the study of organisms at the early stages of development and comparing to different species?
DNA studies

ancestory
paleontology
A mechanism of evolution responsible by a random/chance event that changes allele frequency in a population is known as:
Non-random Mating
Natural Selection
Genetic Drift
Overproduction
Evolved from different ancestors, but due to living in similar environments have a similar function, but different structures.
Homologous structures
Analogous structures
Vestigial structures
All of the above
Whales are aquatic mammals that contain a pelvis (hip) bone. Even though it does not aid in its movement, the function must have been used by a common ancestor of the whale. Thus, the pelvis is referred to as a(n)
vestigial structure
analogous structure
homologous structure

How did prokaryotes form cell membranes?
How are biomolecules formed?
What gave rise to the Eukaryotic cell?
Which of the following is NOT part of the mechanisms of natural selection?
Organisms produce more offspring than can survive.
Disease and natural disaster will limit population growth.
Species today descended with modifications from ancestral species.
Organisms with advantages will survive and reproduce.
