For those who deny either the application of a phylogenetic "ladder" or
of pheromones to species survival:
It is interesting to note that a mating factor in single celled yeasts
(makes them stick together for the exchange of genetic material) is so
similar to mammalian gonadotropin-releasing hormone, that when injected
into mice it elicits a neuroendocrine response similar to that elicited
by exposure to the pheromones of the opposite sex. Whether or not single
celled organisms or humans consciously perceive the effects of
pheromones, chemical communication is ubiqutous in the animal kingdom.
