Infanticide in Primates

Abstract

Infanticide is one of the typical examples used in many general evolutionary hypothesis on vertebrate evolution especially those based on sociobiology. We have shown that this phenomenon is very complicated and in no case can be interpreted as a support for sociobiological ideas. It is not so common a phenomenon in the primate societies as sociologists claim, and even in the “typical” primate species as anhuman langurs, has a very limited and different meaning. Furthermore, there are a lot of examples where many sociobiological hypothesis are based on very superficial and overgeneralized interpretations of nonhuman primate infanticide. In human populations infanticide is usually connected with the cases when the carrying capacity of an ecosystem is no longer sufficient for the survival of a population. It is a conscious action based on longterm empirical knowledge. No negative emotions of even aggressiveness connected with infanticide is know in human groups. We try to demonstrate that the research of primate infanticide gives no consistent basis for its generalization in the framework of sociobiological hypothesis and in evolutionary theories in general.
