11. A divergence from Lobe- finned fishes gave rise to tetrapods.
Hence option (d) is correct.
12. Mammals belong to synapid lineage whereas others belong to Sauropsids lineage..
Hence option ( C) is correct.
13. Reptiles have tough skin, internal fertilization, good kidneys and lay eggs which help them to adapt on land.
Hence option (f) is correct.
14. The earliest members of Genus Homo had a larger brain as compared to others.
Hence option (a) is correct.
15. The closest modern relatives of birds are crocodilians.
Hence option (a) is correct.
16. The frogs live both on terrestrial and aquatic habitats.
Hence the statement is false.
17. Birds have feathers which are not present in any other living organism.
Hence option (C) is correct.
18. Chordates have vertebral column, are tetrapods and are amniotic. Exoskeleton is absent.
Hence option (d) is correct.
19. Homo- erectus evolved in Africa and then dispersed to many regions.
Hence option (C) is correct.
20. Good eye sight of birds is not related to the enhancement of flight. Reduced weight, efficient respiratory system and webbed feet help them in flight.
Hence option (C) is correct.
