Question

g) Patagium of bat and wings of birds are indicative of –

i) palaeontological evidence of evolution

ii) divergent evolution

iii) cursorial adaptation

iv) convergent evolution

h) Normal haemoglobin and sickle cell haemoglobin is an example of –

i) physiological variation ii) morphological variation

iii) psychological variation iv) continuous variation​

Answer 1

Answer:

Development of similar adaptive functional structures in unrelated groups of organisms is called convergent evolution. It shows analogy. Examples are wings of butterfly and birds, eye of octopus and mammals, flippers of penguins and dolphins, etc. On the other hand, divergent evolution involves the modification of organs to perform different functions as an adaptation to different environments. For example forelimbs of vertebrates (whales, bat, cheetah, human). Though these perform different functions, they have similar anatomical structure.

So, the correct answer is 'Eyes of octopus and mammals, Bones of forelimbs of vertebrates'.
