> That aside, I feel it's unfortunate that he chose to illustrate his point by way of analogy, as it seems some of the arguments here are refuting the analogy and not his original point. I disagree. I think it's extremely fortunate. You are acting as if you know all the answers - and you may even think you know all the answers - but I think refusing to consider that biology went through something similar (and I bet there were numerous biologists who wanted to destroy the classification system as it was 'wrong') and found an answer that differs with yours does not mean there is no link. You could be wrong too. Maybe we are missing tools to allow us to alter our classifications later and that classifications are the best solution when given the correct tools.
