    B)  Binocular vision

    D)  Dental formula

    Correct Answer: A

    Solution :

                     Chromosomes of man and ape have been  studied with special staining techniques and it has been established that chromosome of man and apes (especially chimpanzee) have similar banding pattern. The comparision in actual sequence of amino acids in the polypeptide chains of haemoglobin of man, chimpanzee and monkey shows that there is absolutely no difference. The molecular structure of cytochrome-C, insulin and serum albumin in man and apes exhibits minimum difference. The shape, size and arrangement of teeth is different in man and apes. The cranial capacity of apes is 450-600cc whereas of modem man is 1400-1450cc.
