Reasoning of the Different Adaptations of Animals
The duck-billed platypus and the common wombat have different adaptations because they live in different environments and the adaptations they have are suited best for their specific environment. For example a bill of a platypus would not be suitable in a wombats environment because the bill has receptors on it that are used for finding organisms in the water, the wombat does not live in an aquatic environment so the bill would be of no use. In the same way the sharp incisors of a wombat would not be suitable in a platypus' environment because the wombat's teeth are used for eating grass and in the platypus' habitat there are shrimp and crayfish etc.
