Evolution has exhibited a greater stability of the molecular structure when compared with morphological structures. Comment on the statement and justify your opinion

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 lot of diversity all around us. 
  • This diversity is possible because of diversity in morphological structures. 
  • This shows that morphological structures are least stable. 
  • Life which began as simple forms on the earth in now composed of many complex forms. 
  • Life has evolved for millions of years but the structure of basic biomolecules such as DNA remains same. 
  • A DNA is same in a human and in a mouse. 
  • A protein has 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.
