7.Ans. 8 represents the most recent common ancestor of whale and deer.
8.Ans. (d) whale and hippopotamus.
Explanation: Whale and hippopotamus are the two species which evolved most recently from their common ancestor 6. All the species in the phylogenetic tree originated from species 12. On evolution further whale, hippopotamus and deer form a monophyletic group. Horse and cat evolved from their common ancestor 9 and are distantly related to whale and hippopotamus which evolved from species 6.
9.Ans. (b) hippopotamus and deer
Explanation: Deer originated from species 8. Hippopotamus originated from species 8 but it had evolved again at 6 and it makes the two species far related. Farther unrelatedness, more the dissimilarity in their DNA sequence.
10.Ans. These groups and deer form a monophyletic group. Hippopotamus and whale form sister groups. These two are closely related and evolved from their most recent common ancestor 6. These groups and deer form a monophyletic group evolving from their common ancestor 8.
