Compare the bat to the bird. Identify the humerus in each. Where is the bat's ulna? Are there any remnants of it? How is the bat's wing membrane supported by its skeleton? Be precise. (You may wish to examine a preserved bat on the display table.) Does a bird's wing work in the same way? Examine the feathered bird's wing on the display table. What has happened to the bird's hand? How many metacarpals and digits ("fingers") does it have? You may need help from the labeled bird's skeleton on page 8-8. Draw a diagram of the_ separate skeletal elements in a bird's wing and a bat's wing, labeling each major bone humerus, ulna, carpals (wrist bones), metacarpals, phalanges, or digit bones. (This has been an example of two structures which are skeletally homologous and analogous as well.)
