The species is a fundamental concept of biology. It underpins the classification of organisms, our views on evolution and our measures of biodiversity. Research in many fields depends upon general agreement about what a species is. Darwin said: `No one definition has satisfied all naturalists; yet every naturalist knows vaguely what he means when he speaks of a species.’ It is therefore disappointing that there are more species concepts in use today than at any point in the past century, and the consensus in zoology about the Biological Species Concept has begun to unravel. Different species concepts impose different interpretations on the biological world which have important practical consequences.

Dr John Whicher is a retired professor of molecular pathology and experimental cancer research. His research interests were in the mechanism and consequences of the acute phase response.
