Definition of Evolution

Biological evolution is defined as the descent of living things from ancestors from which they differ. Evolution kicks in after there is something, like a replicating structure, to evolve. So the origin of life preceded evolution and is conceptually distinct from it.

~ Dr. Eugenie Carol Scott (1945-10-24 age:71) Evolution vs. Creationism: An Introduction, Second Edition

Creationists make no distinction and like to falsely claim that because science has not definitively cracked the origin of life problem, there must be something deficient in the theory of evolution.
