Detailed explanation-1: -Analogous organs have different origin and basic structure but perform the same function. Examples: Wings of insects and bats are structurally different but perform the same function of flying. Gills of fishes and lungs of rabbits differ in the basic structure but both play a role in breathing.

Detailed explanation-2: -NECs in the gills are considered to be homologous to the airway chemoreceptors of the mammalian lungs (i.e. neuroepithelial bodies, NEBs).

Detailed explanation-3: -homologous is being in similar structures, and having similar genes indicate species are from a common ancestor. Explains that the similarity of the bones of humans’ hands and bones in fish’s fins is the homologous structure.

Detailed explanation-4: -A common example of homologous structures in evolutionary biology are the wings of bats and the arms of primates. Although these two structures do not look similar or have the same function, genetically, they come from the same structure of the last common ancestor.

Detailed explanation-5: -An example of homologous structures are the limbs of humans, cats, whales, and bats. Regardless of whether it is an arm, leg, flipper or wing, these structures are built upon the same bone structure.
