So Darwin and Lyell were both liars; Darwin it seems being the greater liar since his final product contradicted his own findings. Pretty amazing really, but I suppose I shouldn’t be surprised. All in the cause of what???

The above book by Georges Cuvier is one I would love to read.
Darwin had to compromise I guess, that’s why his private journals are so interesting to read. It was Lyell who recommended him to take the journey on the Beagle, he couldn’t write what might basically contradict his patron.
Looking at your question again, I have to add, we can’t really call them liars, they did the best they could with what was available to them. If you read Darwin’s journals, I’m sure you will be filled with admiration as I am.
They don’t have the advantage of being able to update their websites!
