Regulation of ovulation by human pheromones.
Stern K, McClintock MK. Nature. 1998 Mar 12;392(6672):177-9.


Excerpt: "We found that odourless compounds from the armpits of women in the latefollicular phase of their menstrual cycles accelerated the preovulatorysurge of luteinizing hormone of recipient women and shortened theirmenstrual cycles. Axillary (underarm) compounds from the same donorswhich were collected later in the menstrual cycle (at ovulation) hadthe opposite effect: they delayed the luteinizing-hormone surge of therecipients and lengthened their menstrual cycles."

I don't know if there are many other people who have examined cross-species comparisons, but the above excerpt indicates the means by which pheromones can "phase-shift" different events in mammals. This effect had its biological beginning in our evolutionary past. In Kohl (2006) I took it back to yeast cells (e.g., the first cells known to have the ability to sexually reproduce). Overall, this is also consistent with Biblical Creation--from a molecular biology approach. The active chemoreceptors in C. elegans may be the result of receptor diversification that started with yeasts.
