Question

drawbacks of darwinism

Answer 1

Answer:

The three limitations of Darwin's theory concern the origin of DNA, the irreducible complexity of the cell, and the paucity of transitional species. Because of these limitations, the author predicts a paradigm shift away from evolution to an alternative explanation.

Answer 2

Answer:

(1) Darwin took irto consideration minute fuctuating variation as principal factors. But these are neither heritable nor are part of evolution.

(2) Darwin did not distinguish somatic and germinal variation and considered all variations are heritable.

(3) 'Arrival of the fittest' was not explained by him

(4) Darwin was unable to explain the cause, origin and inheritance ot variations and of vestigial organs. He also could not explain extinction of species.

(5) Gradual accumulation of useful variations forms the new species, but their intermediate forms were not recognised.

(6) Darwin could not explain existence of neutral flowers and the sterility of hybrids.
