It’s probably fair to say that, if natural selection had been allowed to run its course, I would most likely fall into the box marked ‘casualty’ than ‘survivor’. Put me in a pack and I’m clearly not the alpha male, either in terms of physical prowess or overall health.┬áIn the animal kingdom I would long since have succumbed to ‘survival of the fittest’. In fact, it would not be unreasonable to say that my continued existence owes┬áitself to a process of unnatural selection.
