Compare the bat to the bird. 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. Does a bird's wing work in the same way? How many metacarpals and digits ("fingers") does it have? (This is all just one question on comparing the bat to the bird)
A human forearm, a horse's front leg, a bat's wing, and a porpoise's flipper have similar bone structure. What conclusions can we draw from the similarities in bone structure between these mammals?
a.
Such homologies do not exist in other areas of the vertebrate skeleton.
b.
Similarities among vertebrate forelimbs suggest they evolved from a common ancestor.
c.
Similarities among vertebrate forelimbs suggest they have evolved convergently.
d.
The anatomy of the vertebrate forelimb is not currently undergoing natural selection.
e.
Differences among vertebrate forelimbs suggest that they evolved independently.
The carpal bones are a set of eight bones that make up the human wrist. These bones are part of which division of the skeleton? A. Compact skeleton B. Axial skeleton C. Subchondral skeleton D. Appendicular skeleton
