Question

Bats and humans are both mammals and share a common ancestor. Because of this, a human arm and a bat wing have similar bone structure. In contrast, bird wings and bat wings have different structures. Explain these relationships in terms of homologous and analogous structures.

Answer 1

Bats and humans are both mammals, so they share a common ancestry.

Both a bat’s wing and a human’s arm share a similar internal bone structure, even though they look very different externally. They arean exampleof homologous structeres. Bat wings and bird wings are Anagolous beacuse they look and work similarly but are NOT related.

Step-by-step explanation:

Homologous structures are structures that may look or function differently from related organisms.

Analogous structures are structures that look and function similarly from unrelated organisms.

Answer 2

A great example of homologous structures are the wings of a bat and the arms of a human. Bats and humans are both mammals, so they share a common ancestry. Both a bat's wing and a human's arm share a similar internal bone structure, even though they look very different externally.
