Question

Which among the following is correct?

Convergent Evolution	Divergent Evolution
(A) Eyes of Octopus and Mammals	Bones of vertebrate forelimbs
(B) Bones of vertebrate Forelimbs	Wings of Butterfly and birds
(C) Bougainvillea thornsand Cucurbita tendrils	Eyes of Octopus and Mammals
(D) Bougainvillea thorns and Cucurbita tendrils	Wings of butterfly and Birds

Answer 1

Convergent evolution or adaptive convergence is development of similar functional structures in unrelated organisms due to similar adaptations. Analogous organs result in convergent evolution.
Examples:
●Eyes of octopus and mammals.

●Wings of butterflies and birds.

Divergent evolution results in the formation of different functional structures as an adaptation to the environment in species having common ancestors.Homologous organs result in divergent evolution.
Examples:
●Bones of vertebrate limbs.

●Thorns of Bougainvillea and tendrils of Cucurbita.

(A) Convergent Evolution- Eyes of octopus and mammals Divergent Evolution- Bones of vertebrate forelimbs.
