The term metamorphosis is not used while describing human development. Why?
उत्तर
The term metamorphosis is not used while describing human development because in human beings, body parts of an adult are present from the time of birth itself, i.e. while beginning of life as a baby and until you are an adult, the basic plan of body does not change.
On the contrary, in metamorphosis, the parts of the adult are different from those at the time of birth.
