- Only mammals possess 3 ossicles in the ear? TRUE OR FALSE?arrow_forwardMammals have a particularly good sense of earing thanks to their inner ear which includes three tiny bones. Reptiles, in contrast, have a single inner ear bone. The lower jaw of reptiles is composed of multiple bones while the lower jaw of mammals is a single bone. Fossil and developmental evidence indicate that the inner ear bones of mammals evolved from lower jawbones. This suggests that the inner ear bones of mammals are 1. an analogy 2. an exaptation 3. a living fossil 4. a transitional trait 5. a vestigial structurearrow_forwardWhy would a frog need to be able to detect higher frequency sounds than a salamander?

- What is the difference between a postorbital bar and fully enclosed eye sockets? What is a bony ear tube? Where is it located? Which larger group of primates has bony ear tubes and which does not?arrow_forwardThere are species of fish that live in caves no longer connected to the surface. These fish have eye structures even though the fish are blind. Why do they have eyes even though the eyes don’t function?arrow_forwardPakicetus is an ancient wolf-like organism that lived 50 million year ago. It had wolf-like ears and nostrils on the front of its skull. Modern whales have a similar ear structure, but their nostrils are on the back of their skull. Aetiocetus lived 25 million years ago, had the same ear structure as both Pakicetus and modern whales, but nostrils in the middle of its skull. According to this information, the most likely conclusion that biologists could draw about the relationship of Aetiocetus to the other organisms is that Aetiocetus...arrow_forward
