What isolation occurs when animals exhibit courting behaviour to attract mates?

• A. Hybrid inviability
• B. Gamete isolation
• C. Behavioural isolation
• D. Mechanical isolation

Answer: (C)

Behavioural isolation is recognized as a significant mechanism in the process of speciation. It occurs when different species develop distinct courtship rituals or mating behaviors that prevent them from interbreeding. In the context of animals, courting behavior can include specific actions, sounds, or displays that are unique to a species. These behaviors serve to attract mates of the same species and ensure successful reproduction, effectively keeping species separate even when they may be in the same habitat. For example, two species of birds may have different songs or elaborate mating dances that only attract individuals of the same species. When members of one species do not respond to the courting behaviors of another species, reproductive isolation is achieved. This emphasizes the importance of behavioral traits in maintaining species boundaries and promoting biodiversity.
