This is a terrible error in reasoning about natural selection.
Because along with novel traits that advance reproductive success can come many other accidental capacities that may have no bearing on survivability.
The human brain is probably the very best example of this. Lets stipulate for a second that its 'rapid' development was due to advantages it provided in hunting (survivability). Seems reasonable. But..... as a generic processing tool, the brain opened up all sort of other capacities that may have had nothing to do with hunting. Like pattern recognition generally. Or enhanced sense of the self. Or a sophisticated sense of time that permitted cause/effect reasoning. The possibilities are countless.
But that aside, there are also good rationales for a beauty sense as a survivability tool, in terms of recognizing health in a mate, in an environment, in forage and prey, etc.
You don't think general pattern recognition is an advantage to survivability?
