The family tree of Lemurs split off from the Last Common Primate Ancestor (LCPA) as 'wet-nosed monkeys', while the other branch of 'dry-nosed monkeys' eventually gave rise to the human lineage. Thus, Lemurs are ancient evolutionary cousins of humans. While humans entirely depend on vitamin C as a dietary supplement (citrus fruits), Lemurs can synthesize their own. This is an example of divergent evolution wherein Lem
Options
- AHumans lost the promoter, but retained rest of the protein coding features in the sequence of gene P .
- BHorizontal transfer of gene P from DNA of dietary citrus fruit conferred vitamin C independence in Lemurs.
- CDry-nosed monkeys do not require vitamin C and therefore have lost the gene P .
- DConsumption of citrus fruits caused mutations in human gene P leading to its loss of function.
Correct answer
A. Humans lost the promoter, but retained rest of the protein coding features in the sequence of gene P .
