If a blue jay sees a normal-looking salamander, it will eat it. But if the same bird sees a freak, it may let it go.So let the aliens first identify the dim-witted, silicone-implanted bigot as this planet's prey, and maybe they'll leave the rest of us alone?
University of Tennessee researcher Benjamin Fitzpatrick says this discovery, which his team reports in the open access journal BMC Ecology, suggests why rare traits persist in a population.
Predators detect common forms of prey more easily, the scientists figure. The majority that share a common look are always on the dinner menu, while oddballs are left to reproduce.
No, I haven't gone insane, but I thought this aspect of evolution was refreshing. Finally a theory that doesn't postulate that freaks die a sad and lonely death!
