Nonsense - there is no way that the members of a species can consciously know what would be the most successful way to achieve an outcome.There are forces within any species that gear towards that that ensures the most successful outcome, whether consciously or directed.
If by "direction" you mean our evolved DNA - yup - We are DNA factories. Elephants make more elephant DNA, oaks produce more oak DNA, gnats make more gnat DNA and humans make more human DNA.
If you mean something other than DNA - what?
No -So that we don't go to far, take humans males for example; on a primeval basis, without specific cultural bias, most of them around the world would prefer and be attracted to the almost hour glass figure of females in order to mate and procreate, now take that female figure and let's say for example that for some biological reason, females with that shape can't after a while procreate, the pressure on males would be to switch to let's say for example to a pear shape female that is fertile every time. Here natural selection is taking place,and in humans is not only instinctive, but also a choice.
1- You assume that men only want to mate with women who are going to produce their children - even though they cannot tell whether a women can have children. That is contrary to human behaviour.
2 - You misunderstand "natural" selection - under your scenario natural selection would result in a mainly pear-shaped population of women and men's preferences would become irrelevant.
I hope you enjoyed your film - I suggest next time you have a couple of spare hours you read up on natural selection
