Convergent Evolution

• The process by which organisms that are not closely related come to resemble one another

• The evolution of different species from a common ancestor

• The adaptation of organisms to their environment over time

• The process of species becoming extinct due to environmental changes

Genetic Drift

• Random change in allele frequency

• A process of natural selection

• A method of genetic engineering

• A type of mutation

Extinction

• The permanent disappearance of a species from Earth, meaning no remaining individuals of that species exist anywhere

• A significant reduction in the population of a species, but not complete disappearance

• The process by which a species evolves into a new species over time

• The temporary decline in the number of individuals of a species due to environmental changes

Founder effect

• Allele frequencies change as a result of the migration of a small subgroup of a population to found a new population.

• Allele frequencies remain constant in a large population over time.

• Allele frequencies change due to random mating within a population.

• Allele frequencies are influenced by natural selection in a stable environment.

Co-evolution

• The process by which 2 species evolve in response to changes in each other over time

• A method of genetic engineering to create hybrid species

• The phenomenon where species become extinct due to environmental changes

• The adaptation of a species to a single environment without interaction with others

Adaptive Radiation

(Divergent Evolution)

• When a single species evolves into diverse forms that live in different ways.

• When different species evolve similar traits due to similar environments.

• When a species becomes extinct due to environmental changes.

• When two species evolve independently but develop similar traits.

Punctuated equilibrium

• a pattern of gradual change over time.

• a pattern of long, stable periods interrupted by brief periods of more rapid change.

• a theory that all species evolve at the same rate.

• a model that suggests evolution occurs in a linear fashion.

Sexual Selection

• Characteristics that provide survival advantages.

• Characteristics that give organisms a reproductive advantage.

• Characteristics that are randomly selected by nature.

• Characteristics that are inherited from ancestors.

gradualism

• Darwin believed that evolutionary change occurs rapidly and in bursts.

• Darwin felt that, much like geologic change, evolutionary change was slow and steady.

• Darwin argued that evolution is a random process without any direction.

• Darwin suggested that species do not change over time.
