ABSTRACT
This Dictionary provides an explanation of the main ideas of and concepts central to biology. Rather than offer an exhaustive list of technical terms, the author has selected a range of basic terms that are likely to meet the needs of most readers and librarians. The entries cover not only the traditional subject areas but also many of the topics that form the distinctive parts of human and social biology. Each entry in the Dictionary of Biology begins with a clear, one-sentence definition, followed by a further explanation, and, where appropriate, by specific examples. Numerical ideas are supported by working examples. Entries are cross-referenced, and the A-Z arrangement makes the book very easy to use.
