The parasite that causes malaria edges through the cells of the stomach wall of the mosquito and forms a cyst which grows and eventually bursts to release hundreds of sporozoites into the body cavity of the mosquito ... As far as we can tell, the parasite does not harm the mosquito ... It has always seemed to me, though, that these growing cysts ... must at least give the mosquito something corresponding to a stomach-ache.

The world of organisms, of animals and plants, is built up of individuals. I like to think, then, of natural history as the study of life at the level of the individual-of what plants and animals do, how they react to each other and their environment, how they are organized into larger groupings like populations and communities.

Natural history is not equivalent to biology. Biology is the study of life. Natural history is the study of animals and plants-of organisms. Biology thus includes natural history, and much else besides.
