1. Examine the butterfly wing and the bird wing shown in Figure 2. butterfly wing bird wing Figure 2. a. What function do these structures share? b. How are these structures different? c. Do birds and insects share any structural (elements inside the wing) similarities that would suggest they are closely related taxonomically? Some apparently unrelated animals have organs with similar functions, yet are very different in structure and form. These structures are called analogous structures. PART III. VESTIGIAL STRUCTURES (definition):

Step 1
- The primary shared function of both butterfly and bird wings is to enable flight. These structures allow both types of animals to lift their bodies into the air and move through it. Show more…

Bird wings and dragonfly wings are both used for flight is it homologous structure or analogous structure

Describe an analogous structure. a. A penguin and a seagull both have wings. The penguin uses wings to swim while the seagull uses wings to fly. b. Lizards and whales have similar skeleton structures, but they have a different habitat and lifestyle. c. Birds and butterflies have wings with similar characteristics for flight even though their wings do not share an evolutionary relationship. d. The bone structure in leg of a cat is very similar to the bone structure in the arm of a human, but the functions of the limbs are very different.

Insects have three thoracic (trunk) segments. While researchers have found insect fossils with pairs of wings on all three segments, modern insects have wings or related structures on only the second and third segment. It turns out that in modern insects, Hox gene products act to inhibit wing formation on the first segment. The treehopper insect (above) is somewhat of an exception. In addition to having wings on its second segment, the treehopper's first segment has an ornate helmet that resembles a set of thorns, which a recent study has found to be a modified, fused pair of "wings." The thorn-like structure helps to camouflage the treehopper in tree branches, thus reducing its risk of predation. Explain how changes in gene regulation could have led to the evolution of such a structure.
