Document Summary
Carolus linnaeus developed the concept of binomial nomenclature. James hutton worked with rocks (claims that the world is changing a bit every second) Land forms by mechanism that are currently operating in the world. The natural laws that operate now have always been operating. Refined hutton"s gradualism to uniformitarianism (world is changing) Species evolve through inheritance of acquired characteristics proposed a mechanism for evolution! Proposed natural selection as one mechanism of evolution. Natural selection = one evolutionary mechanism, differential survival and reproduction. Population = a group of the same species that is interbreeding and sharing a gene pool. Variation = members of a population often vary greatly in their traits. Overproduction = more offspring are produced than can survive. Individuals with most favorable characteristics are most likely to survive and reproduce. Leads to accumulation of favorable traits in pop over generations. Darwin was heavy influenced by thomas malthus, an economist. Organism must compete with each other for resources.
