Excerpt from The Evolution of the Vertebrates and Their Kin
It is many years since a sustained attempt has been made to unite the various branches of the animal kingdom into a natural, coherent system, or genealogical tree, that would indicate the rise and decline of the important functions and organs, map out the highways of organic evolution, and assign in geological terms the approximate dates and surroundings for the critical events in structural in novation and readjustment that have marked its progress.
The most important problem involved in such an undertaking is to discover which one, if any, of the many existing invertebrate phyla forms the trunk line of descent from the lowest vertebrates to the coelenterates, and through them to the protozoa.
