उत्तर
All living organisms existing on earth show immense diversity in size, form, structure and morphological features but at the molecular level, these organisms exhibit unbelievable similarity. For instance, these organisms are made up of the basic biomolecules like DNA, RNA, carbohydrates, proteins etc. which show remarkable similarity in all of them. DNA in all organisms is made up of same units (nucleotides) and has the same double-helical structure. So, evolution has exhibited a greater stability of molecular structure when compared with morphological structures.
