It is easy to be critical of Darwin and chief among criticisms of him is that his theories are proven to be wrong and because it is said Darwin recanted them on his death-bed. But it is not wise to despatch this early scientist to the dustbin of history. Certainly he was limited in his ability to undertake research and therefore much of his theory has its foundation on the Scientist’s meagre observations through a very primitive microscope.
Darwin had no means to be able to research the general complexities of biology, let alone the specifics of Gene Science, chromosomes and their DNA chains, blood typing etc etc. So we need to cut him a bit of slack if his thoughts got railroaded as a result of this lack of scientific knowledge and its development.
