Evolution Pretest

any trait or behavior that increases an organisms likelihood of survival

the natural process whereby those varieties in a population that are better adapted for the environment are more likely to survive nature's forces than those varieties that are not well suited for the environment

a small change within a population

a large scale change in a population that results in the creation of a new species

any change in the DNA sequence; produces new adaptations in a population

measured by the ability of an organism to reproduce fertile offspring

the genes available for intermixing in a population when reproduction happens

comparing the similarities in embryonic development in organisms with the idea that the more similar development occurs between two species the more closely related they are

the study of how living things are distributed on the earth

using similarities in DNA Sequences and amino chains that make up proteins to show close evolutionary relationship

comparing similarities in body structure to show evolutionary relationship

a branching tree showing the inferred evolutionary relationships between species

a diagram showing the relationship of organisms based on the existence of certain derived characters or adaptations

using the remains of living organisms to document evolutionary relationship
