Family Feuds

Intraspecific aggression takes place when individuals of the same species clash to compete for mates, food, territory… perhaps even such resources as a waterhole in which to cool off in summer. This is different to interspecific competition, which takes place when different species compete for a common resource, for instance water in a shrinking pond, or a kill by a leopard that is claimed by either a tiger, or wild dogs. Essentially, it is the coding built into their genes that drives their instincts.

As is the case with economics, all resources are essentially scarce and such scarcity is what keeps populations in check. Such intraspecific competition may seem violent, or even cruel to us, but such dominance is key to the survival of the fittest on Planet Earth.

Animals are aggressive not because they are savage, or bestial or evil (those are words with very little explanatory power) but because such behaviour provides food and defence against predation, because it spaces out the population and avoids overcrowding, because it has adaptive value.” - Carl Sagan, Shadows of Forgotten Ancestors

"Animals use aggression as a technique for gaining control over necessities... that are scarce or are likely to become so... They intensify their threats and attack with increasing frequency as the populations around them grow.” – E.O. Wilson

Each individual and each social group is prepared to resort to force, and to exert force to the utmost, if necessary, in order to defend its interests. Defensive fighting pays.” - Wallace Craig, International Journal of Ethics

The danger of too dense a population of an animal species settling in one part of the available biotope and exhausting all its sources of nutrition and so starving can be obviated by a mutual repulsion acting on the animals of the same species… This, in plain terms, is the most important survival value of intraspecific aggression.” – Konrad Lorenz

 And this leads me to say a few words on what I call Sexual Selection. This depends, not on a struggle for existence, but on a struggle between the males for possession of the females; the result is not death to the unsuccessful competitor, but few or no offspring.” - Charles DarwinThe Origin of Species

The notable thing about animal fights is that they are formal tournaments, played according to rules like those of boxing or fencing. Animals fight with gloved fists and blunted foils. Threat and bluff take place of deadly earnest.” - Richard Dawkins

To a survival machine, another survival machine (which is not its own child or another close relative) is part of its environment, like a rock or a river or a lump of food. It is something that gets in the way, or something that can be exploited. It differs from a rock or a river in one important respect: it is inclined to hit back. This is because it too is a machine that holds its immortal genes in trust for the future, and it too will stop at nothing to preserve them.” - Richard Dawkins
