The implication seems pretty obvious to me: according to the episode, as well as mainstream creationism, the human species is a desired end product of a project. This is the exact opposite of a natural process of evolution, where the human species is neither an end product nor a desired goal, but merely something that happens to meet the requirements of the day and survive until better things come along.
Yeah, I get that, but what I'm saying is, where did the Precursor chaps come from? We can't really posit an infinite regress of founding races. So presumably the Precursors were the products of evolution. That artificial cell created by Craig Venter isn't the product of evolution, but its existence doesn't conflict with evolution. So in this case, 'Venter' = the Precursors and 'Humans, etc' = the artificial cell.
