Within the early 17th century, the result of anything so simple as a cube roll was once consigned to the area of unknowable likelihood. Mathematicians principally agreed that it used to be very unlikely to foretell the chance of an prevalence. Then, in 1654, Blaise Pascal wrote to Pierre de Fermat explaining that he had stumbled on find out how to calculate chance.

1996), has resulted in a renaissance in research on olfaction and to the surprising and occasionally controversial suggestion that the rodent olfactory system could serve as a model for neurobiological studies of cognition (Reid and Morris, 1993; Slotnick, 1994). (p. 216) An inherent problem with the pheromone concept when applied to mammals is that, by implication and definition, it obfuscates or excludes from consideration the possibility that cognitive processes are involved in the mediation of chemically induced behavioral and endocrine responses.

3 In an introduction to a bibliography on mammalian pheromones, Whitten and Champlin (1972) provide a state-of-the-art description of what pheromones were believed to be in the early 1970s and add the observation that chemicals that are truly pheromones are most likely found in only one sex. They also suggest that some chemicals are “copheromones” and replace the term releaser pheromone with behavioral pheromone. [Pheromones are] substances, produced by one member of a species, which influence other members of the same species.

As noted by Porter and Winberg (1999), “The role of maternal olfactory signals in the mediation of early breast-feeding is functionally analogous to that of nipple-search pheromone as described in nonhuman mammals. To some extent, the chemical profile of breast secretions overlaps with that of amniotic fluid. Therefore, early postnatal attraction to odors associated with the nipple/areola may reflect prenatal exposure and famil- 38 T H E G R E AT P H E R O M O N E M Y T H iarization” (p. 439). , 1995), as well as affect the flavor of the mother’s milk.
