Change over time; the process by which modern organisms have descended from ancient organisms

Selective breeding of plants and animals to promote the occurrence of desirable traits in offspring

Process by which organisms that are most suited to their environment survive and reproduce most successfully; also called survival of the fittest

Hardy-Weinberg Principle

Allele frequencies in a population remain constant unless one or more factors cause those frequencies to change

When individuals select mates based on heritable traits; sometimes known as sexual selection

Random change in allele frequency caused by a series of chance occurrences that cause an allele to become more or less common in a population

The movement of genes into or out of a population

A change in allele frequency following a dramatic reduction in the size of a population

Change in allele frequencies as a result of the migration of a small subgroup of a population

Heritable characteristic that increases an organism's ability to survive and reproduce in an environment

How well an organism can survive and reproduce in its environment

Homologous structures

Structures that are similar in different species of common ancestry

Body parts that share a common function, but not structure; structures that evolved independently

Structure that is inherited from ancestors but has lost much or all of its original function

The study of the form of organisms (mainly focusing on anatomy)

Preserved remains or traces of ancient organisms

Evolutionary group of great apes that includes humans

Term used to refer to two-foot locomotion

Hypothesis that before DNA was used as the primary nucleic acid, an earlier, more primitive nucleic acid was used

A branch of science devoted to organizing species into groups based on evolutionary heritage

Diagram depicting patterns of shared characteristics among species

Organism that is able to capture energy from sunlight or chemicals and use it to produce its own food from inorganic compounds; also called a producer

Organism that obtains food by consuming other living things; also called a consumer
