write objections against Darwin's theory
Answers
Answer:
Some of the objections to the theory of natural selection, which Darwin explained vaguely are the following:
Darwin's theory stresses upon small fluctuating variation which are to a large extent non-inheritable and can play no role in evolution.
His theory does not explain the effect of use and disuse and the presence of vestigeal organs.
Darwin could not explain whether the instincts are acquired and modified through natural selection.
He could not differentiate between somatic and germinal variation's and considered all variations as heritable.
Natural selection cannot account for degeneracy.
One of the classical objections to natural selection is that new variation would be lost by 'dilution' as the individuals possessing them breed with others without them.
Darwin indirectly accepted the Lamarckian idea of inheritance of acquired characters in the form of 'pangenesis hypothesis', which cannot be accepted in the light of knowledge of genetics.
