Most people still conceive different types of biological taxa and place them in ranks: some taxa are species, others are genera, while others are families. Linnaeus gave us his ranks in 1731. Although biological theory has changed since Linnaeus' time, the vast majority of biologists still assign Linnaean ranks to taxa, even though the practice is at odds with evolutionary theory and even though it causes a number of practical problems. Some authors abandon Linnaean ranks and propose alternative methods for displaying the hierarchical relations of taxa.
Whatever the view on this it must be remembered that ranking is a subjective decision. This explains why taxa may be ranked differently by different authors.
