There are a lot of pros and cons to using the biological concept. It is only one out of several types of concepts used to define a species. What would be the main criterion used for determining / differentiating between species? gene flow O niche differences O geographical isolation
Which of the following is NOT a limitation of the current biological species concept? O Some scientists say that we should use DNA similarities to determine species. O It is difficult to apply to asexually reproducing organisms. O It is difficult to apply to species that are extinct. Some organisms can breed in captivity but would not breed in nature. Some organisms are obviously separate species but are sometimes able to mate and

You are studying two variations of banana slugs. They have similar coloration and live in the same habitat. Although they are physically able to mate, there are no offspring that survive embryologic development. What can you conclude about the banana slugs? * O Pre-zygotic barriers have forced them to be separate species. They are in Hardy-Weinberg equilibrium. O Microevolution is occurring in both variations. O They are two separate species.
