"Correction... Evolution is concerned with how life began, and how DNA has manifested in phenotypes over successive generations."
No, it isn't concerned with the origins of life. Nice try though :)
Sure it is. In order to determine how change has occurred, if any at all, there has to be an origin. This is why the missing link is so important to the study of human evolution.
Humans did not evolve from apes; this much is a certainty in human evolutionary study. If evolution is concerned with human origin, it also is interested in life's origin. All living things have DNA...
