Vedclass · Answer

(A) Homologous organs are those that have the same basic structural plan and embryonic origin but perform different functions. $1$. The forelimbs of humans,monkeys,kangaroos,and the trunk of an elephant (which is a modified nose/upper lip) share a common ancestral skeletal structure,making them homologous. $2$. Wings of insects,birds,and bats are analogous organs because they perform the same function (flight) but have different evolutionary origins. $3$. Hindlimbs of grasshoppers (insects) and mammals (horses/bats) have different structural origins. $4$. Mouthparts of cockroaches,mosquitoes,and honeybees are analogous as they have evolved for different feeding habits despite being modified appendages.

Which of the following groups represents homologous organs?
