How a Science Fight Finally Led to World's First Global Species List in 2020 STEPHEN GARNETT ET AL., THE CONVERSATION 9 JANUARY 2021 Taxonomy, or the naming of species, is the foundation of modern biology. It might sound like a fairly straightforward exercise, but in fact it's complicated and often controversial. Why? Because there's no one agreed list of all the world's species.
Competing lists exist for organisms such as mammals and birds, while other less well-known groups have none. And there are more than 30 definitions of what constitutes a species. This can make life difficult for biodiversity researchers and those working in areas such as conservation, biosecurity and regulation of the wildlife trade.
