Opis

Excerpt from The Voyage of H. M. S. Challenger, Vol. 31: Zoology; Report on the Alcyonaria Collected by H. M. S. Challenger During the Years 1873-76 A natural classification of a group should no doubt be the record of its evolution, and should exhibit at a glance the stages through which the varied forms passed on their way to the attainment of their present positions. A very thorough knowledge of the life history of existing forms, and of the measure of their variableness, would be necessary ere the outlines of such a classification could be attempted, and for the filling in of the details one would require also a knowledge of extinct forms. Unfortunately for the perfection of such a scheme among the Alcyonaria there is no appeal to palaeontology, the phenomena which are of most importance, - such as the structure and relations of the canal system, the structure and development of the individual polyp forms, - can never in fossil forms be known, owing to their being incapable of preservation in tables of stone.
