Some researchers claim that apes can learn the rudiments of human language. Of any species of animal, they are the closest to man on the phylogenetic tree. A prevailing theory of social behavior asserts that sexual hormones promote aggression. Neutering of dogs is therefore said to promote social behavior. In the wild, wolves are never neutered and yet they are the most social and cooperative species of animal on earth.
Male dogs are more aggressive than female dogs.
Statistically, dominance is the most prevalant form of aggression according to modern behavioral interpretation. Survival is always reported to be the baseline and fundamental criteria of animal behavior and instinct. But even when wolves are well fed on moles and voles, they will still seek out large prey animals which decrease their chance of survival. Many dogs likewise will chase cars which also decrease their chances for survival. Hopefully this brief test demonstrates that the prevailing models for animal learning and canine social organization are lacking a model which can account and contain the many intricacies of behavior and learning.
