When does behavioral isolation occur in the process of speciation?
A
When two populations are separated by physical barriers
B
When two populations occupy different ecological niches
C
When two populations have different numbers of chromosomes
D
When two populations develop different mating behaviors
Verified step by step guidance1
Understand that speciation is the process by which populations evolve to become distinct species.
Recognize that behavioral isolation is a form of reproductive isolation, which prevents different species from interbreeding.
Identify that behavioral isolation occurs when two populations develop differences in mating behaviors or rituals, which can prevent them from recognizing each other as potential mates.
Different mating behaviors can include variations in mating calls, courtship rituals, or other behaviors that are critical for attracting mates.
Conclude that when two populations develop different mating behaviors, they are less likely to interbreed, leading to behavioral isolation and potentially contributing to speciation.
