Origin of 'pheromone'

The term 'pheromone' was coined in 1959 by Carl Larsen and Peter Karlson, derived from the Greek words 'pherein' which means 'to carry' and 'hormone' which refers to substances that evoke a response in organisms. The concept emerged from research in entomology when scientists observed insects responding to specific chemical signals. Initially, pheromones were primarily studied in insects, where they were found to influence mating, alarm signaling, and foraging behavior. As research expanded, scientists recognized pheromones' role in various species, including mammals and humans, in areas such as social interaction, habitat selection, and reproductive strategies. The study of pheromones has implications for understanding animal behavior, ecology, and for developing potential uses in pest control and human applications like fragrances and social dynamics.
