Where did Darwin err in his theory of the “Origin of Species” through natural selection ?

Solution

Darwin's theory had following drawbacks :

1. Survival of the fittest. Darwinism can explain the survival of fittest but is unable to account for arrival of the fittest. It is difficult to suppose that small variations could have formed organs like wings and mimicry colouration which are useful only in their fully developed state.

Certain organs can be helpful to the organism only in fully developed state and what about their presence in early stages.

2. Over specialization. Tusks of elephants and the antlers of some deer have overgrown their usefulness.

3. Vestigial organs. A number of vestigial organs persisting generation after generation has no explanation according to Darwinism.

4. Darwin did not differentiate between somatic and germinal variations.
