Evolution Concepts Review

The process in which individuals that have certain inherited traits tend to survive and reproduce at higher rates than do other individuals because of those traits

• gene flow

• genetic drift

• mutation

• natural selection

The process where in change in allele frequency is brought about by chance alone

• genetic drift

• migration

• natural selection

• non-random mating

The process wherein alleles flow in and out of a population due to the migration of individuals or gametes

• gene flow

• genetic drift

• mutation

• non-random mating

This process is the original source of new alleles in a species

• gene flow

• migration

• mutation

• non-random mating

This process results in an increase in the frequency of individuals with desirable traits

• genetic drift

• migration

• natural selection

• non-random mating

Animals share similar structures due to shared ancestry

• analogous

• homologous

• natural

• random

Animals have similar structures without shared ancestry

• analogous

• homologous

• natural

• random

How do scientists determine evolutionary relationships

• through analogous structures

• through DNA sequences

• through homologous structures

• through all of these

Natural selection

• is a theory and supported by facts

• is the same as selective breeding done by farmers

• means nature and not humans "selects" individuals with favorable traits

• ensures that only favorable traits are passed on from generation to generation

What evolutionary relationships may be inferred? Check all that apply. (All or none)

• That domestic dogs are the more evolved canid species

• Domestic dog is closely related to the grey wolf.

• The domestic dog and the grey wolf share a common ancestor.

• Jackals are the ancestors of both domestic dog and grey wolf.
