A) Evidence from DNA from sex chromosomes only
B) Comparison of chromosomes morphologically only
C) Evidence from fossil remains and the fossil mitochondrial DNA alone
D) Evidence from DNA extracted from sex chromosomes, autosomes and mitochondria
Correct Answer: D
Solution :
Chimpanzee is more closely related to man than other Hominoids. It is supported by chromosome banding pattern, DNA extracted from sex chromosomes, autosomes and mitochondria. Molecular clock based on mitochondrial DNA is used to date recent events because this DNA mutates 5-10 times faster than nuclear DNA. Some similarities between human and chimpanzee are- [a] DNA matching shows that human resembles 100% with chimpanzee. [b] There is little difference in banding pattern in chromosome 3 and 6 in human and Chimpanzee. [c] Serum test indicates maximum homology between human and chimpanzee.
