“…our phylogenetic heritage includes systems enabling the attribution of a positive or negative value, driving attraction to or avoidance of odorants. This suggests that, upstream of the hedonic plasticity occurring throughout life, we are endowed with a partly predetermined neural basis for these odor hedonic representations–even if the odorant has no biological significance, such as predator, conspecific…”

This article makes cross-species comparisons that will help extend what most of us here know about human pheromones. We respond to them because they (like other chemical input) are very biologically significant.
