Adaptation Quote by Richard Dawkins
“I think nobody would claim that random genetic drift is capable of producing adaptation, that is to say the illusion of design. Random genetic drift can't produce wings that are good at flying, or eyes that are good at seeing, or legs that are good at running. But random genetic drift probably is very important in driving evolution at the molecular genetic level.”
About This Quote
Source Book: The Selfish Gene, Richard Dawkins, 1976
Random genetic drift does not create complex adaptations but influences genetic variation at the molecular level.
In simple terms: Drift reshuffles genes, not designs.
