Even though marsupials known as sugar gliders and flying squirrels are members of distinctly different groups of organisms and live on different continents, they possess similar characteristics. This is an example of .

Analogy

Explanation:

Analogy simply refers to possession of similar traits, or structures that are similar in function, by two different species organisms that have no common origin. Analogous structures become evolved separately in different organisms that share similar needs for survival or adaptation in their different environments.

Sugar sliders and flying squirrels both look very similar in appearance and structure, as they evolved separately to adapt to similar lifestyle, but do not orginated from a common ancestor. One example of similarity between both is the piece of skin that they have stretched between their legs, which looks like wings that make them stable while gliding. Sugar sliders and flying squirrels are analogous as they have evolved separately to become adapted to gliding in their different environments.
