Vedclass · Answer

(A) Homologous organs are those that have the same structural origin and developmental plan but may perform different functions.$A$. Wings of a butterfly (insect) and wings of birds are analogous organs. They perform the same function (flight) but have different evolutionary origins and structures (butterfly wings are membranous extensions,while bird wings are modified forelimbs).$B$. The heart of vertebrates is homologous as it shares a common structural plan despite variations in complexity.$C$. The brain of vertebrates is homologous as it follows a common developmental pattern.$D$. The forelimbs of mammals (e.g.,whale,bat,cheetah,human) are classic examples of homologous organs as they share the same skeletal elements (humerus,radius,ulna,carpals,metacarpals,and phalanges) despite being adapted for different functions like swimming,flying,running,or grasping.
