I still remember how torn I was when I first read about the counter-intuitive possibility that natural selection could favor suicide. Apparently, sometimes one can increase one’s inclusive fitness by looking into barrel of a gun. Now, as it turns out, natural selection can favor also functional necrophlia. Read more about it from here, or consult the original publication. And who are these corpse humpers? Our beloved frogs.
