Cuvier- catastrophism: catastrophes caused extinct species and strata. Darwin and wallace developed the theory independently: darwin- voyage of the beagle, wallace- british naturalist in indonesia. Darwin"s focus on adaptation: form is how something is shaped or made, the form dictates the function. Concept 22. 2 evolution is supported by an overwhelming amount of scientific evidence.
