Answer: Structure which are apparent to our eyes are called morphological structures. Molecular structures are those biomolecules which are the integral components of organisms. We see a lot of diversity all around us. This diversity is possible because of diversity in morphological structures. This shows that morphological structures are the least stable. Life which began as simple forms on the earth is now composed of many complex forms.

Life has evolved for millions of years but the structure of basic biomolecules such as DNA remains the same. A DNA is the same in a human and in a mouse. A protein has the same structure in a bird and in a fungi. So, the molecular basis of life has not changed through all these years. This proves that evolution has exhibited a greater stability of molecular structure when compared with morphological structure.
