Orks, a Collection of Varying Subspecies

Tolken's portrait of the ork as a collection of very diverse kindreds is biologically very accurate, except that is, for one thing, sex. The enormous ety of orks can be seen as a consequence of the smallness and isolation of populations,. evolving in their own particular ways to suit local conditions. And incomprehension, evolutionary theory tells us that evolution happens faster and has more idiosyncratic results when populations are small and isolated.
