Two populations of organisms are too similar in appearance

Last updated: 7/26/2022

Two populations of organisms are too similar in appearance for scientists to identify them as different biological species based on visual inspection alone. How can scientists determine whether the two populations belong to different species or are simply subpopulations of the same species? Test whether the two populations can thrive if their habitats are swapped. Identify differences in size and structure between the two populations. Observe the two groups for differences in behavior and food choice. Determine whether mixed breeding pairs will produce fertile offspring.
