The Morphological Species Concept

The Morphological Species Concept defines a species based on observable physical traits and structures, such as size, shape, and appearance. If organisms look similar enough in their features, they are classified as the same species. This approach is useful when genetic information isn't available or when working with fossils. However, it can be limited because different species might look alike, and individuals of the same species can sometimes vary in appearance. Overall, it relies on visible characteristics to distinguish groups of organisms as distinct species.
