Homologous organs

Vedclass · Answer

(B) The correct answer is $B$ (Homologous organs).Homologous organs are those organs which share a common ancestral origin and have the same fundamental anatomical structure,but perform different functions due to adaptation to different environments.In the provided diagram,the structures shown (such as thorns of Bougainvillea and tendrils of Cucurbita,or various leaf modifications) represent homologous structures because they all arise from the axillary position,indicating a common developmental origin despite their different functional modifications.Homologous organs are the result of divergent evolution,where species with a common ancestor evolve different traits to adapt to diverse ecological niches.
