Cave fish have eyes, but they do not work. Based on the species name, why does it not need to be able to see? sto vid Does the appearance of the cavefish and the minnow suggest a common ancestry? Why? 3. Assume the two fish came from the same common ancestor. Why might the cave fish have evolved without eyesight? In your explanation use the following terms: trait, inherited, natural selection. What kind of alternative sensory adaptation would you hypothesize the cave fish has to allow it to navigate a cave without sight, including catching and eating food?

5c) Do you believe that experiments might be useful in determining the adaptive function of the pecten, if it indeed serves an adaptive function? Outline a simple experiment to see whether the presence of a pecten in the bird eye is an adaptation.
All primates have two eyes that face forward. This includes humans. Having two eyes is an evolutionary advantage and provides binocular vision, which means that two eyes are involved in the visual process. One of the advantages of having two eyes is the ability to perceive depth. Depth perception is achieved by: a. analyzing the differences in the images falling on the left and right eyes b. allowing light rays to converge and project an upside down image on the retina c. the optic chiasm d. changing the shape of the lens to accommodate the distance of an object

1. Observe the behavior of the live goldfish. Note the movement of the operculum. What is its function? Does a shark have an operculum? 2. Examine the model of the bony fish. Compare the fins, shape of the tail, scales and other external features with the shark. How do the fins of fish contribute to the evolutionary story of animals evolving to life on land? 1. Observe and compare the features of the amphibian specimens. 2. The frog will be used to review vertebrate anatomy. Begin by examining the thin skin of the frog. How does it compare to the skin of a reptile? Would the frogs skin help protect it against water loss? How is the frog able to supply its body tissues with enough oxygen even if there is some mixing of oxygenated deoxygenated blood? Amphibian, literally means “living on both sides”. Explain why amphibians have that name. What characteristics do reptiles have that make them more suited for terrestrial life than amphibians? Why are birds thought of as flying…
