Evolution Illustrated by Waterfowl by David Lack. Illustrations by Robert Gillmor. Blackwell Scientific Publications, Australia, 1974. In association with the Wildfowl Trust.
Condition: Used – good. The soft-cover has creases from use and bumps to edges, otherwise in a good condition. The pages are bright and clean, the binding and spine are fine.
Extracts: In Britain, fifteen species of waterfowl breed regularly and a few more do so occasionally, while another twelve are regular and a few others occasional in winter.
How did this diversity of forms come into existence, and why do they differ from each other? The problem is, in miniature, that all animal life, and the waterfowl have been used in this booklet to show the main principles of animal classification and evolution.
