Statigraphy

The study of the earth's layers or strata

Uniformitarianism

Idea that the earth was changed through a series of natural processes

Cataprophism

Georges Cuvier

Believed that animals changed through the inheritance of acquired characteristics (created the word biology)

Lamarck

Believed in overreproduction

Thomas Malthus

Put the idea of natural selection, origin of species

Charles Darwin

Came up w/ the same idea of natural selection as Charles Darwin

Alfred Russel Wallace
