In a year when so much has been published on evolution in the animal kingdom it is interesting to read a book on seeds, which lie at the heart of evolution in the plant kingdom. The author traces the evolution of angiosperms from fernlike ancestors - as with sex in animals, seed production has enabled plants to spread into virtually all habitats on earth, displaying an enormous diversity in form and function.  

Silverman explores the diversity of seeds from tiny dustlike particles in the case of orchids to the huge double coconut, their dormancy and germination, and their storage of nutrients for the early boost to plant life.

The evolutionary success of food plants has in turn been of enormous importance to animal life, and the author outlines how we humans have taken advantage of their storage of starch and oils in our production of food and drink. Seeds have a dark side too, and Silverman outlines the many plants which produce poisonous substances such as ricin and cyanides. We also take advantage of the flavouring properties of seeds in our use of coffee, chocolate etc. 

This book is one of those that keep our attention with many interesting sidelights from the witches of Salem to Lyme disease.
