This is the semantics thing EB is talking about Oversoul... Evolution doesn't have a "goal" other than adaptation. But, without procreation, evolution fails... And... not unjustly, so does creation... regardless of how it came to be, if species were unwilling, unable, or poor at procreation, that species existence ends... Species Evolution depends on procreation, and also on adaptation - through mutations big and small... Sometimes it's invisible, for example Sherpas require less oxygen to breathe than other humans. In a regular oxygen environment they are fine, in a deprived oxygen environment, say on Mt Everest, they excel because they don't require the same amount of oxygen the rest of us do. This is evolution, since they live at a higher elevation with lower levels of oxygen, their offspring who were best suited for the environment survived and procreated, making a perhaps recessive gene become predominent among them. But, it's not exclusive to them I would bet. It's just that others don't test it by climbing Everest. And since they don't live in environments where it's an advantage, it's not necessarily passed on. If the successful ones fail to procreate, they will not pass on the successful trait... Procreation isn't a "goal", it's a requirement. Just because a gene is recessive, does not mean it's in the minority... Take blood type for example. Type O is recessive, but most humans are type O.
