Question

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

Answer 1

Evolution : The phenomenon by which various kinds of living organisms are believed to be developed from earlier forms during the history of the earth.

Evolution and Morphological structures:

1. Morphological structures are visible structures or more precisely external features.
2. There is a great diversity due to the variety of morphological structures, which indicates the least amount of stability.
3. The DNA of a human and a mouse is identical, also the protein in a bird and a fungus has the same structure.
4. After all these years, the chemical underpinning of life has remained unchanged.
5. This is the reason why it is said that evolution has exhibited greater stability of the molecular structure when compared with morphological structures.
