When two organisms, such as a predator and prey, evolve in response to one another

Evolution that results in the formation of analogous structures

Slow change in allele frequencies over long periods of time

When allelic frequencies are stable and unchanging, therefore evolution is not occurring

A physical trait that increases an organism's ability to survive in its environment

Principle of natural selection that explains how beneficial traits should become more common over time, causing a change in allelic frequencies

When two organisms, such as a predator and prey, evolve in response to one another

All of the genes available in a population

A physical trait that increases an organism's ability to survive in its environment

When traits that favor reproduction, even though they may decrease an organisms ability to survive, become more common over time

Principle of natural selection that explains how harmful traits should become more common over time, causing a change in allelic frequencies

When traits that favor reproduction, even though they may decrease an organisms ability to survive, become more common over time

All of the genes available in a population

Biological change over time that causes descendants to be different from their ancestors

Organisms with traits that make them better adapted to their environment will live longer and reproduce more than organisms less adapted to the environment

When isolation, such as geographically, causes two populations of organisms to become so different that they can no longer reproduce with each other and create viable offspring

Study of body structures to provide evidence of evolution

When isolation, such as geographically, causes two populations of organisms to become so different that they can no longer reproduce with each other and create viable offspring

Evolution that results in the formation of homologous structures

Slow elimination of species caused by small environmental changes over extended periods of time

Evolution that results in the formation of analogous structures

Evolution that results in the formation of analogous structures

When traits that favor reproduction, even though they may decrease an organisms ability to survive, become more common over time

Evolution that results in the formation of homologous structures

Biological change over time that causes descendants to be different from their ancestors

Flightless birds, like the ostrich, are an example of this

Sudden elimination of a species due to a catastrophic event

Slow elimination of species caused by small environmental changes over extended periods of time

When an individual dies

Slow elimination of species caused by small environmental changes over extended periods of time

Extinction that results in the formation of analogous structures

Sudden elimination of a species due to a catastrophic event

Study of body structures to provide evidence of evolution

Principle of natural selection that explains how beneficial traits should spread & become more common over time, causing a change in allelic frequencies

When two organisms, such as a predator and prey, speciate in response to one another

When isolation, such as geographically, causes two populations of organisms to become so different that they can no longer reproduce with each other and create viable offspring

The wings of flightless birds, like the ostrich, are an example of this

Body structures that are similar in orientation, but completely different in function due to organisms living in different environments

Similar body structures, such as fins, due to organisms living in the same environment, not same ancestry
