Connecting link
Advertisements
Solution
- A connecting link is an organism that shows characteristics of two different groups of organisms. For example, Peripatus is considered a connecting link between annelids and arthropods.
- It has features such as a segmented body, a thin cuticle, and parapodia-like appendages, similar to those of annelids.
- It also possesses tracheal respiration and an open circulatory system, as in arthropods.
- Another example is the Duck-billed Platypus, which acts as a connecting link between reptiles and mammals because it lays eggs like reptiles and has mammary glands like mammals.
