Social intelligence in the spotted hyena (Crocuta crocuta).
If the large brains and great intelligence characteristic of primates were favoured by selection pressures associated with life in complex societies, then cognitive abilities and nervous systems with primate-like attributes should have evolved convergently in non-primate mammals living in large, elaborate societies in which social dexterity enhances individual fitness. The societies of spotted ...
متن کاملSociety, demography and genetic structure in the spotted hyena.
Spotted hyenas (Crocuta crocuta) are large mammalian carnivores, but their societies, called 'clans', resemble those of such cercopithecine primates as baboons and macaques with respect to their size, hierarchical structure, and frequency of social interaction among both kin and unrelated group-mates. However, in contrast to cercopithecine primates, spotted hyenas regularly hunt antelope and co...
متن کاملMammalian sexual differentiation: lessons from the spotted hyena.
Female spotted hyenas (Crocuta crocuta) are the only female mammals that lack an external vaginal opening. Mating and birth take place through a urogenital canal that exits at the tip of a hypertrophied clitoris. This 'masculine' phenotype spurred a search for an alternate source of fetal androgens. Although androstenedione from the maternal ovary is readily metabolized to testosterone by the h...
متن کاملExact Cardinality Query Optimization for Optimizer Testing
The accuracy of cardinality estimates is crucial for obtaining a good query execution plan. Today‟s optimizers make several simplifying assumptions during cardinality estimation that can lead to large errors and hence poor plans. In a scenario such as query optimizer testing it is very desirable to obtain the “best” plan, i.e., the plan produced when the cardinality of each relevant expression ...
متن کاملPost-weaning maternal effects and the evolution of female dominance in the spotted hyena.
Mammalian societies in which females dominate males are rare, and the factors favouring the evolution of female dominance have yet to be clearly identified. We propose a new hypothesis for the evolution of female dominance and test its predictions with empirical data from the spotted hyena (Crocuta crocuta), a well-studied species characterized by female dominance. We suggest that constraints i...
