Lecture 1&2

Uniformitarianism the theory that changes in the earth's crust during geological history have resulted from the action of continuous & uniform processes
Ecological diversification the evolution of divergent ecological characteristics within a lineage
Descent with modification (word used by Darwin instead of evolution) all organisms are related through descent from a common ancestor that lived in remote past. Overtime, adaptations accumulate that allow them to survive & reproduce in specific habitats
Natural selection (mechanism for evolution) a population of organisms can change over generations if individuals having certain heritable traits leave more offspring than other individuals
Lyell geologist that proposed theory of uniformitarianism, also influenced Darwin's theory of evolution
Lamarck french biologist that explained observations of fossil invertebrates with principle: use & disuse of parts & the inheritance of acquired characteristics; thought that evolutionary change was driven by innate drive of organisms to increasing complexity
Malthus wrote essay on human population that influenced Darwin's views on over reproduction; much of human suffering was consequence of potential for human populations to increase faster than food supplies & other resources
Wallace sent Darwin a manuscript containing theory of natural selection
