the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth
the process whereby organisms better adapted to their environment tend to survive and produce more offspring
the intentional reproduction of individuals in a population that have desirable traits
is a trait with a current functional role in the life of an organism that is maintained and evolved by means of natural selection
to the total number of fossils that have been discovered, as well as to the information derived from them
means the ability to survive to reproductive age, find a mate, and produce offspring
the diversification of a group of organisms into forms filling different ecological niches
the process whereby organisms not closely related , independently evolve similar traits as a result of having to adapt to similar environments or ecological niches
variation in the relative frequency of different genotypes in a small population, owing to the chance disappearance of particular genes as individuals die or do not reproduce
collection of evolutionary mechanisms, behaviors and physiological processes critical for speciation
a population of animals, plants, or other organisms that are separated from exchanging genetic material with other organisms of the same species
the action or art of imitating someone or something
adaptation that allows animals to blend in with certain aspects of their environment
having the same function but have evolved separately, thus do not share common ancestor.
structures or attributes that have lost some or all of their ancestral function in a given species, but have been retained during the process of evolution
underlining anatomical commonalities demonstrating descent from a common ancestor
A British naturalist of the nineteenth century. He and others developed the theory of evolution
believed that living things evolved in a continuously upward direction, from dead matter, through simple to more complex forms, toward human "perfection."
was a Scottish geologist, physician, chemical manufacturer, naturalist, and experimental agriculturalist.
