Divergence of species-specific protein sex pheromone blends in two related, nonhybridizing newts (Salamandridae) Vrije Universiteit Brussel KU Leuven
In animals that use chemical communication during courtship and reproduction, speciation is often associated with divergence of their sex pheromones. In multicomponent pheromone systems, divergence can be obtained either by adding or deleting components, or by altering the relative contribution of individual components to the mixture. Protein pheromone systems can additionally evolve by amino acid sequence divergence to produce pheromones with a ...
