Document Summary
Breadth and scope of theory- nothing in biology makes sense except in the light of evolution - theodosius dobzhansky. Evolution is the only unifying scientific theory in the study of life. Observational methodology gives very contextual, and highly valid, data. Evolution is a theory that explains the diversity and function of all living things. Evolution is a theory, but so is electricity or gravity. Evolution is the most powerful, and widely accepted, theory in biology. Darwin was interested in explaining the wide variety of life forms that existed. Earlier theories existed e. g. , lamarkianism (inherit traits that change during lifespan; e. g. , lifting weights will give you stronger children) (what you do in your life changes how your kids will be) You can"t change your genes based on what you do. Darwin came up with the theories of natural and sexual selection. Five components of darwin"s evolution by natural selection: more offspring are born than survive to reproduce.
