Charles Darwin was a creationist and became a believer and Christian on his death bed.
That’s not only irrelevant it’s also an urban legend that isn’t true. The Lady Hope story was debunked by Darwin’s children shortly after his death. According to Darwin’s children, who were present when he died, not only did Darwin not renounce evolutionary theory, Lady Hope wasn’t even there. Nor was she present during his illness or any illness. In fact Darwin had never even met Lady Hope. In short, Lady Hope lied.
Hell even the ICR debunks that urban legend as untrue. It didn’t happen.
It’s irrelevant because Darwin didn’t formulate his famous theory in a vacuum. It was long known by geologist that the earth’s origin was far more ancient than had been believed and naturalist before Darwin had observed and noted how the geological record gave evidence of species changing over time. There were also peers to Darwin in his own time who made the same conclusion independently. Notably Alfred Wallace.
What Darwin did was piece the evidence painstakingly together to provide a functional predictive model of speciation that he published in a scientific and literary masterpiece “On The Origins of Species”. That is why evolutionary theory is named after him.
The point being that the principal of evolution was known before Darwin and the evidence that we’ve learned since then has supported Darwin’s observation and, more importantly, the theory has been updated and revised with these additional discoveries like the laws of genetics, nucleic acids (RNA/DNA), protein structures and synthesis. All of which could have easily have falsified evolutionary theory but haven’t. They have, in fact, provided stronger support and deeper understanding of evolutionary theory which has been correspondingly revised to account for this new knowledge.
Darwin in his own time did not know what the physical mechanism of natural selection was and understood that it was a weakness in his theory. He just observed natural selection and how it functioned. We now know from later discovery that genetics and the biological properties of nucleic acids are the underlying mechanism of natural selection.
Darwin did not know what this mechanism was in his time but had faith that it would be discovered. What is ironic is that even as Darwin wrote it that very discovery had already been made by a cloistered Austrian Monk. Ironic ehh?
