Question

Evolution has exhibited a greater stability of molecular structure

when compared with morphological structures. Comment on the

statement and justify your opinion.

Answer 1

We See immense diversity in size, form, structure and morphological features in the living world. But at the molecular level these diverse types of organisms exhibit unbelievable similarity. For instance, the basic biomolecules like DNA, RNA, carbohydrates proteins, etc., exhibit remarkable similarity in all organisms. Thus we can say that evolution has exhibited a greater stability of molecular structure when compared with morphological structure.
hope it does help you :)

Answer 2

Answer:

Evolution of molecular structure shows greater stability as compared to morphological structures changed over time. Various biomolecules are required to make an organism. The diversity that is seen around the world arises as a result of morphological structure. Life starts with a simple form and slowly it evolved into a complex form of life. Therefore, it can be said that the morphological structure show the least stability.

However, if we considered the molecular level, all the organism are made up of same biomolecules like protein, DNA, carbohydrates, and lipid etc. The structure of DNA is the same in all the organism, irrespective of the type of organism.

Hence, it can be said that molecular structures show great stability.
