Vedclass · Answer

(A) Homologous structures are those that have a common evolutionary origin but may perform different functions. $A$. The eye of a mammal and the eye of an octopus are analogous structures,as they evolved independently to perform the same function (vision) but have different embryonic origins. $B$. The forelimbs of a cheetah and a whale are homologous,as they share the same skeletal structure (humerus,radius,ulna,carpals,metacarpals,and phalanges) despite different functions. $C$. The heart and brain of vertebrates are homologous organs,as they share a common ancestral structural plan. $D$. The thorns of Bougainvillea and tendrils of Cucurbita are homologous,as both are modified branches sharing a common origin. Therefore,the eye of a mammal and the eye of an octopus represent convergent evolution and are $NOT$ homologous.

Which of the following does $NOT$ represent homologous structures?
