Bats wings?

Question

Give an example of both an evolutionary analogy and an evolutionary homology for a bat’s wing. Clearly indicate which is which.

Answer 1

you really should do your own homework, dude.

look in your "introduction to physical anthropology" textbook.

Answer 2

Analogy:  Birds' wings

Homology:  Human arms.

Answer 3

An evolutionary ANALOG would be any wing-structure not evolutionarily related to the bat. Birds, flying fish, things like that.

An evolutionary homologue would be any wing structure that derived from the same ancestor as the wing of the bat did. So, for that, just pick something from the same order, in this case Chiropetera:

(Flying foxes are probably the easiest.)

Here is a ppt from a college course that might help you better understand the concept:
