Aristotle
founded the scala naturae, at a time when species were thought to be created individually by God.
Scala Naturae
"evolutionary ladder" each species had an "ideal" structure and place
Buffon
french naturalist, often professed to believe in special creation and the fixity of species.
Lamarack
first biologist to believe that evolution does occur and to link diversity with adaptation to the environment.
Lyell
wrote principles of geology, which supported James Hutton's theaory of geological change. Went and proposed a theory of uniformitarianism concluding that extreme geological change can be accounted for by slow natural processes, given enough time, and they occur at a uniform rate.
Darwin
gathered evidence that organisms are related through common descent and that adaptation to carious enviornments results in diversity
Wallace
English naturalist who independantly proposed natural selection as a process to explain the origin of species.
Malthus
stressed the reproductice potetial of human beings. He proposed that death and famine were inevitable because the human population tends to increase faster than the supply of fod.
Catastrophism
Belief espoused by Georges Cuvier that periods of catastrophic extinctions occurres, after which repopulation of surviving species took place, giving the appearance of change through time.
Uniformitarianism
Belief espoused by James Hutton that geological forces act at a continuous uniform rate
Acquired Characteristics
links diversity with adaptation to the environment. (the environment can bring about inherited change)
Biogeography
study of the geographic distrubution of life-forms on Earth.
Natural selection
Mechanism of evolution caused by enviornmental selection of organisms most fit to reproduce; results in adaptation to the enviornment. (see book also)
Kin selection
Kin selection was first suggested by Darwin as an explanation of the sterile castes of social insects and has later been mathematically defined by W. D. Hamilton as a mechanism for the evolution of apparently altruistic acts. Kin altruism is the technical term for altruistic behaviour that has been shown, or is theoretically supposed, to be explained by kin selection.
Fossil
Any past evidence of an organism that has been preserved in the Earth's crust.
