adaptation
A Darwinian adaptation is an organism's feature that was functionally designed by the process of evolution by selection acting in nature in the past.
DNA
The amount of difference in DNA is a test of the difference between one species and another – and thus how closely or distantly related they are.
DNA evidence confirms Darwin's central hypothesis: that heritable variation arises continually and is gradually accumulated, making lineages steadily diverge from each other

fossil
fossil records
Among the thousands of plant, animal, rock and fossil specimens Darwin collected while aboard the Beagle, he collected 13 species of fossil mammals.

-
fitness
a measure of how well organisms survive and reproduce, with emphasis on "reproduce."
-
analogus structure
features of different species that are similar in function but not necessarily in structure and which do not derive from a common ancestral feature
homologus structure
organs or skeletal elements of animals and organisms that, by virtue of their similarity, suggest their connection to a common ancestor.
vestigal structures
a biological structure that has lost a major ancestral function and is usually drastically reduced in size.
artifical selection
the identification by humans of desirable traits in plants and animals, and the steps taken to enhance and perpetuate those traits in future generations.
-
embryos
The study of one type of evidence of evolution is called embryology, the study of embryos.
