Neutering, from the Latin neuter ('of neither sex'), [1] is the removal of a non-human animal's reproductive organ, either all of it or a considerably large part. The male-specific term is castration , while spaying is usually reserved for female animals.
Population control is the practice of artificially maintaining the size of any population.It simply refers to the act of limiting the size of an animal population so that it remains manageable, as opposed to the act of protecting a species from excessive rates of extinction, which is referred to as conservation biology.
The book pioneered and popularized the attempt to explain the evolutionary mechanics behind social behaviors such as altruism, aggression, and nurturance, primarily in ants (Wilson's own research specialty) and other Hymenoptera, but also in other animals. However, the influence of evolution on behavior has been of interest to biologists and ...
Surgical castration in animals is often called neutering. Castration of animals is intended to favor a desired development of the animal or of its habits, as an anaphrodisiac or to prevent overpopulation. The parallel of castration for female animals is spaying. Castration may also refer medically to oophorectomy in female humans and animals.

The XO sex-determination system (sometimes referred to as X0 sex-determination system) is a system that some species of insects, arachnids, and mammals (not including humans) use to determine the sex of offspring.
Human ethology is the study of human behavior. Ethology as a discipline is generally thought of as a sub-category of biology, though psychological theories have been developed based on ethological ideas (e.g. sociobiology, evolutionary psychology, attachment theory, and theories about human universals such as gender differences, incest avoidance, mourning, hierarchy and pursuit of possession).
Hermaphroditic animals and dioecious plants represent a large portion of sexually reproductive species. Under social selection theory, species where individuals produce two different gametes predate strictly gonochoristic and monoecious species. Separate sexes can, therefore, be described as derivations of primal hermaphrodites.
