    ... where the new alpha male comes in and kills the offspring of the last alpha male he just defeated in a fight..., which then triggers an estrus cycle for the females and he impregnates them so the next cubs that come along he does not kill but are half his DNA?

    I'm a chicken for watching that just now, in other words.

    Sometimes Mother Nature's methods for species survival with diversity leaves much to be desired.  Inbreeding replicates weaknesses - as well as strengths in some cases - and lines become extinct because of the lack of diversity.  It's why domestic dogs and cats have certain problems that are genetic - arthritis, hip dysplasia, and the like.  It was the inbreeding of dogs bred for certain traits that got dogs to the point of being the most diverse species on the planet..., and all have DNA traceable to a dog somewhere in Asia thousands of years ago.

    With cats, I used to see ads in two different cats magazines where it specified Scottish folds were from fold & straight eared matings.  Fold-to-fold matings resulted in such horrors as kittens born with open brains.  Extreme smooshed-in faces of some dogs or cats can sometimes result in offspring born with open faces.  Inbreeding for extremes of traits is just not a good thing.

    Still... I don't get why in certain animal packs - lions, for one, langurs, for another (and maybe chimps in the wild?) - where the offspring who were sired by the previous alpha male are killed.  The new alpha male does not kill his own later after they're born, just the ones from the previous male.  It's a particularly cruel way to get DNA passed on relatively quickly since the offspring next born of those females he mated with will carry his DNA.

    I'm sick of attempts to steer this nation from principles evolved in The Age of Reason to hallucinations derived from illiterate herdsmen. ~ Crashing Vor
