Biology Quote by Stephen Jay Gould
“You put three facts together - that all organisms produce more offspring that can survive, that there's variation among organisms, and that at least some of that variation is inherited - and the syllogistic inference is natural selection.”
About This Quote
Source Book: The Structure of Evolutionary Theory, Stephen Jay Gould, 2002

A Different Perspective
Selection works only when variation is heritable and environmental pressures exist.
![“[T]ruly grand and powerful theories [...] do not and cannot rest upon single observations. Evolution is an inference from thousands of independent sources, the only conceptual structure that can make unified sense of all this disparate information.
