a greek philosopher who entertained the notion that organisms change through time
a greek philosopher who believed that all living thins can be arraged in a hierarchy, i.e. some organisms are more complex than others. Also he believed that all living things had always existed
Carolus Linnaeus
he believed that all living things came into beingin their present form, from a divine creation and were created solely for the purpose and pleasure of mankind. But he believed that the pattern of creation was far more complex than previously thought. He came up with the classification system we use today
Georges-Louis de Buffon
most createures came about by divine creation, BUT species undergo changes, changes caused by a process of degeneration because of nature and time
Erasmus Darwin
species have historical connection with one another; species change in response to their enviornment and some of these changes can be inherited by offspring
James Hutton
a geologist who showed that the Earth was produced by a slow and gradual process = Uniformitarianism. Fossils really do tell us something about the earth and its life forms
William Smith
a geologist who saw that the earth's strata, no matter where found, contianed similar forms of fossils; so it seems that the surface of the earth was formed layer by layer
Georges Cuvier
a geologist that held that many species that once existed no longer do = extinction
Louis Agassiz
a geologist that held that extinctions occur with an equal number of new, separate creations
Jean Baptiste Lamarck
1) all species are descended from other species
2) living things are constantly increasing in complexity. from studying fossils he noticed that complex forms come from simpler forms through a progression, which he called "evolution" which was dependent on 2 forces
(1) the inheritance of acquired characterisits: i.e. big muscles from a body building couple would mean big muscles for their offspring
(2) the universal principle: organisms are constantly striving to become more complex, e.g. worm trying to become human
Charles Lyell
he reverted to uniformitarianism = slow and steady change over a long period of time
Charles Darwin
he saw different tortoise types came from different islands as did different types of finch and mockingbirds. He saw a constant, continuous change up and down coastlines, and from mountian top to sea level. Organisms had filled new niches and had taken on new roles and characterisitics, based on where they lived
Alfred Russell Wallace
came to the same conclusions that Darwin did and came up with them independently of him. Wallace actually sent his findings to Darwin, just as Darwin was trying to pull it together. Wallace got little credit
Thomas Malthus
influenced Darwin and looked at food supplies and other factors that kept populations in check
