Not all characters are homologies. Insects (class Insecta) have segmented bodies, jointed legs, and external skeletons. Animals that have wings are insects, birds and bats. Insects can have wings like birds, but insect and bird wings are considered analogous structures instead of examples of taxonomical relatedness. Process by which unrelated organisms independently evolve similarities when adapting to similar environments. For example, the wings of a birds and insects have the same function, but they do not reflect a shared ancestry. Insects are distinguished from other arthropods by their body, which is divided into three major regions: (1) the head, which bears the mouthparts, eyes, and a pair of antennae, (2) the three-segmented thorax, D. … For example, the wings of birds, the front flippers of whales, the forearms of a chimp, and the front limbs of a frog or lizard are all homologous structures, even though a whale's flipper, could not be more different than the front limbs of a lizard from outward appearances or from their functions. The wings of bats are made of skin, which is stretched between the bones of the bat's arms and fingers. Loading... Close. Learn more at 23andme.com. Thus, … The ancestor of tetrapods evolved four limbs, and its descendents have inherited that feature — so the presence of four limbs is a homology. The similarities are due to similar environmental pressures rather than to common ancestry. C. analogous structures. The wings of insects, birds, and bats evolved independently but carry out similar functions. As such, wings have streamlined cross-sections that are subject to aerodynamic forces and act as airfoils. A familiar example is the wings of insects birds and bats All three groups of from ANTHRBIO 161 at University of Michigan are called homologous structures. This means that _____. Analogous organs are the opposite of homologous organs, which have similar functions but different origins. Since insects are invertebrates and birds are vertebrates, they diverged quite early in evolutionary history. So, the option C is not correct.Vestigial organs are the organs that are present in the body but not perform any function. The wings of birds, bats and insects evolve independently but have same superficial structure and performs same function. The main difference between wings of insects and birds is that the wings of insects lack bones whereas the wings of birds have bones.Furthermore, the wings of insects have a number of longitudinal veins, which are cross-connected, while the wings of birds are covered with feathers. A wing's aerodynamic efficiency is expressed as its lift-to-drag ratio. This video is unavailable. b.com (hons)C.U Asked in Insects ? 12. Asked in Insects How does an insect fly? examples of insects [4] Insects: invertebrates with bodies divided into three parts; they usually have three pairs of legs, two pairs of wings and antennae. Now consider the example we have here - bird and butterfly wings.
