well, i havent' had biology since AP bio in 11th grade, and have only added to that knowledge through what i've read on the internet. but the study of evolution only deals with how life has changed since it it began. not how life began (abiogenisis). technically, you could probably take it all the way back to the development of self-replicating non-life. like proteins, then whatever came next, and next, and next all the way to the first single celled organism. but evolution, strictly speaking, doesn't deal with that (at least as far as i know).
