explain the terms analogous and homologous organ with example Those organs which have different basic structure or different basic design but have similar appearance and perform similar functions are called analogous organ . The wings of an insect and the wings of a bird are analogous Organs Solution: The organs which are anatomincally different but perform similar functions are called analogous organs. For example, insect and birds wings are different in basic structure and origin because insect wing is formed from integument while the bird wing is a modified forelimb but functionally both are adapted to flight Similar traits can be either homologous or analogous. Homologous structures share a similar embryonic origin. Analogous organs have a similar function. For example, the bones in a whale's front flipper are homologous to the bones in the human arm. These structures are not analogous. A butterfly or bird's wings are analogous but not homologous The human body contains five organs that are considered vital for survival. They are the heart, brain, kidneys, liver, and lungs. The locations of these five organs and several other internal organs are shown in Figure 10.4. 2.

Vestigial organs have long been one of the classic arguments used as evidence for evolution.The argument goes like this: living organisms, including man, contain organs that were once functional in our evolutionary past, but that are now useless or have reduced function The opposite of homologous organs are analogous organs which do similar jobs in two taxa that were not present in their most recent common ancestor but rather evolved separately.For example, the wings of insects and birds evolved independently in widely separated groups, and converged functionally to support powered flight, so they are analogous.. Similarly, the wings of a sycamore maple seed.
HOMOLOGOUS ORGANS Homologous organs may be defined as the organs of different animals which have similar basic structure but different functions. For example, the flippers of a whale, the forelimbs of a frog and man have the same basic structures. Analogous definition is - similar or comparable to something else either in general or in some specific detail : similar in a way that invites comparison : showing an analogy or a likeness that permits one to draw an analogy.

Analogous structures are structures that are similar in unrelated organisms. The structures are similar because they evolved to do the same job, not because they were inherited from a common ancestor. For example, the wings of bats and birds, shown in Figure below, look similar on the outside. They also have the same function It is similarity in organs based on similar function. Organs which have different origin and dissimilar fundamental structure but have similar functions are called analogous organs. The differentiation of class characters appear in the later stages, moreover, the embryo of phylogenetically higher vertebrates pass through the adult stages of.
