Species/Kinds (for Peg...and others)

So what was Linnaeus purpose when he proposed his taxonomic scheme in 1735?
He managed to put species into taxonomic groups based on morphology long before the ToE was conceived. For example humans were put into the order Anthropomorpha which included primates and sloths, and this was part of the class Mammalia. I realise you probably think classifying species is unimportant, since the diversity you've experienced seems to be what you've seen out your back window, but scientists have discovered millions of different organisms and need some way to categorise them so we know what we are referring to.
