Animal studies

• Most of our knowledge of the effects of pheromones on behaviour is derived from animal studies where their role in animal sexual selection is well-documented.
•  One example of this is sea urchins releasing pheromones into the surrounding water so other urchins in the colony will eject their sex cells simultaneously
• In contrast, evidence for the effects on human behaviour remains speculative and inconclusive
• ‘Animal extrapolation’ refers to the process of explaining human behaviour through the study of animals.

  Here we rely on the predictive power of animal studies on humans
