There is nothing wrong with celebrating Darwin, he was an important scientist and a nice guy to boot. I would agree that the neo-Darwinists have gone WAY overboard with it all the reverence. The most important progress in evolutionary biology happened in the last 50 years. Darwin and Wallace simply set the stage for the modern synthesis.
Darwin was not a scientist. Nor did he follow the scientific method. He was a med-school dropout turned amateur naturalist. Origin of Species was largely devoid of scientific evidence. It was nothing more than a long argument advocating a complete reinterpretation of biological history based on minor variations between finches.
