Cannibalism seems to be only in extreme conditions where the animal loses its mind? Again I have not learnt anything about it. Survival of the fittest actually means (not offending you) continuation of species which genetically adapts to the changing environment, that I can accept. In a paleontology lecture I learnt that horses once had two nails, they were dull and dog-sized. That species of horse did not survive but those who ran for their life eventually become more muscular, agile and one-nailed. They passed their traits in the form of genes to their offsprings, which improved them even more and so on.

Then we had our modern horse birthing in slowly. It's evolution. I can accept that. Scammers, on the other hand should be eliminated completely and the 'fittest', those who are able to make a healthy living, should be continued, in my opinion.
