Excerpt from Primitive Animals The object of this little book is to present a simple account of modern views on the relationships of the chief groups of the animal kingdom, the principal grounds on which the modern classification of these groups may be justified, and an outline of the evidence by which some of the main streams of animal evolution can be traced. The science of comparative anatomy with its theoretical super-structure of phylogeny (the ancestral pedigree of animals) rests so largely upon facts which can only be satisfactorily appreciated by a course of laboratory experience, that it is difficult to present the subject intelligibly to readers who have not already acquired some discipline in zoological science, but, to those who are acquainted with the structure and development of a few types of animals, it may prove instructive to consider some of the wider problems of animal relationship, and to link up their knowledge of special types with a more general appreciation of the probable course organic evolution has taken.
