Final answer:
The morphological species concept is better than the biological species concept because it emphasizes reproductive isolation mechanisms, is applicable to both sexual and asexual organisms, and considers genetic compatibility between individuals based on physical traits.
Step-by-step explanation:
The morphological species concept is better than the biological species concept for several reasons. First, it focuses on reproductive isolation mechanisms which are essential for determining species boundaries. Second, it can be applied to both sexual and asexual organisms, making it more applicable in a wider range of situations. Finally, it considers genetic compatibility between individuals by looking at their physical traits, which helps in distinguishing between different species.
