An illustration related to human evolution is given. Analyse it and answer the following questions: How does the comparative study of haemoglobin helped to identify the evolutionary relationship between man and chimpanzee ?

Different organisms have been evolved in different times. These have been classified for identification purposes. Chimpanzees and humans both belong to the family Hominoidea. A comparative study of haemoglobin explains how an ancestral single-function molecule gave rise to descending molecules with varied functions. Haemoglobin is the molecule in red blood cells responsible for giving blood its colour and for carrying oxygen throughout the body. Evolutionary evidence suggests that there is no difference in the number of amino acids in the chain of haemoglobin found in the man or chimpanzee. It also suggests the same evolutionary roots of these organisms.
