What's answer to question 4? 1. In terms of the differences between the opossum, bird, bat, and mole skeletons which youexamined, which is most like the human (and therefore, most primitive or generalized)?2. Which is least like the human and, therefore, the most specialized ?3. Most anatomists consider bats more specialized than moles; but what important differencescan you see between the mole's forelimbs and that of humans? Why is the front limb of themole so specialized? Can you identify: the humerus, clavicle, and scapula in the mole?8-114. Compare the bat to the bird. Identify the humerus in each. Where is the bat's ulna? Arethere any remnants of it? How is the bat's wing membrane supported by its skeleton? Beprecise.Does a bird's wingwork in the same way? Examine thebird's wing on the display table. What hashappened 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.

The animal kingdom has diverse firms of organisms constructing millions of species. Bats are mammals…

1) Of all of the robust australopithecines, I am the most primitive, dated to 2.5 mya. I have an enormous sagittal crest on the top of my head, a back of the skull that looks like A. afarensis, and am quite prognathic. My discovery seemed to justify my removal from the genus Australopithecus, and the creation of an new genus with two other species sharing similar anatomy..................... 2.
