Detailed explanation-1: -What is a pheromone? A Pheromone is a chemical produced by a given species that affects the behavior or physiology of the same species – first coined by Karlson and M. Luscher in 1959. Early work was in insects, but scientists soon discovered that pheromones operate in other animals, including mammals.

Detailed explanation-2: -Pheromones are chemicals produced by one species that affects the physiology or behavior of animals of the same species. Pheromones assist in reproduction, feeding, social interactions and maternal-neonatal bonding in mammals. By definition and according to evolutionary theory, pheromones work within a species.

Detailed explanation-3: -Pheromones are chemical substances that are created and emitted by organisms as odorants-often as oils or sweat-into the environment that may influence the behavior or physiology of other members of their species.

Detailed explanation-4: -What Are Pheromones? Pheromones are chemical signals that have evolved for communication between members of the same species. A pheromone signal elicits a specific reaction in the receiver, for example, a stereotyped behavior (releaser effect) or a developmental process (primer effect).
