Courses on the invertebrates have two principal aims: (1) to introduce students to the diversity of animal life and (2) to make them aware that organisms are marvellously integrated systems with evolutionary pasts and ecological presents.

Courses on the invertebrates have two principal aims: (1) to introduce students to the diversity of animal life and (2) to make them aware that organisms are marvellously integrated systems with evolutionary pasts and ecological presents.

It is, in a sense, a general biology of the organism - not, however, of organisms as static unchanging systems, but of organisms as dynamic entities which progress through a definite cycle of events from birth to maturity.

This book is concerned with physiological studies that make evolutionary considerations explicit.
