Book – Why do we group some species of animals together, to say these are more like each other than they are like something else? And how do we know we’re right? Carol K. Yoon, a biologist turned science writer, argues that the “right” way to classify things depends on what we’re organizing them for, and in this case, the scientifically “right” way may actually be entirely wrong for the rest of us. Naming Nature is structured around the idea of the umwelt, the natural human sense of the living world around us. Linnaeus, the father of modern taxonomy, worked almost entirely out of his own well-developed umwelt.
Unfortunately, the umwelt does not match up at all with the distinctions important to science – the evolutionary history of species. So the history of modern taxonomy has been a history of ever-more precise definitions of evolutionary relationships which are also ever-more distant from the way humans actually see the world. (For instance: scientifically speaking, there is no such thing as fish, as a category.) Yoon concludes that, given that humans seem to be more and more disconnected from the natural world, we should leave scientific taxonomy to science and re-take folk taxonomy for the rest of us. For most people fish exist, and unless you’re a scientist that’s all that matters.
