Terms in this set (20)

A trait that helps an organism survive and reproduce
Change in a kind of organism over time; process by which modern organisms have descended from ancient organisms.
A well tested concept that explains a wide range of observations
Process by which individuals that are better suited to their environment survive and reproduce most successfully; also called survival of the fittest
Selection by humans for breeding of useful traits from the natural variation among different organisms
Difference among members of a species.
Structures in different species that are similar because of common ancestry.
The theory that evolution occurs slowly but steadily
Pattern of evolution in which long stable periods are interrupted by brief periods of more rapid change
Traveled to the Galapagos Islands on the HMS Beagle and later wrote the book "The Origin of Species."
Strategy in which organisms make more offspring than will actually survive.
All the fossils throughout the history of the Earth that are used as evidence of evolution.
An ancestral species from which later species evolved
Study of developing embryos used as evidence of evolution.
A structure that is present in an organism but no longer serves its original purpose (ex. hip bones in whales)
Genetic information that can be used as evidence of evolution between organisms.
When members of a species become separated which may lead to the evolution of new species.
Evidence of Evolution

3) Homologous Structures
5) Vestigial Structures
