Excerpt from The Ancestry of Vertebrates: As a Means of Understanding the Principal Features of Their Structure and Development Those who have read the book to the end will admit that this theory, to say the least of it, merits earnest consideration. They will admit that, unlike most other similar theories, it not only serves to explain known facts but that also its application has advanced us further in several respects. Of these I will mention here only the problem of the hypoglossus and its relation to the gill-slits and the cranium (cf. Plate and the results given in the last chapter. In the treating of the different problems, I have tried each time to give the reader first an idea of the divergent opinions and the confusion often prevailing. Though this does not make the reading of the book easier and more agreeable - problems having been made often much more complicated by the investigators than they are in reality I have thought it advisable to do so in order to emphasize the value of a means of escaping from this confusion. The expressing of a persons thoughts correctly in a foreign language is no easy matter. I 'am greatly indebted, therefore, to Mr. Humphreys, officer of the Royal Flying Corps who was interned in The Hague during the year 1918. For having gone over with me the whole article, and to Mr. Moon, engineer of Batavia, for having once more reread with me the proofs If in spite of this the English be not yet perfect, I trust that these imperfections, if any, will not give rise to any misunderstandings.

The vertebrate integument arose about 450 million years ago as an ‘armour’ of dermal bony plates in small, jawless fish-like creatures, informally known as the ostracoderms. This book reviews the major changes that have occurred in the vertebrate integument from its beginnings to the present day. Critical questions concerning the origin, structure and functional biology of the bony integument are discussed and intrinsically linked to major steps in vertebrate evolution and phylogeny—the origin of jaws and the origin of teeth. The discussions include the origins of mineralization of major vertebrate skeletal components such as the dermatocranium, branchial arches and vertebral column. The advances that led to the origin of modern fishes and their phylogenetic development are reviewed and include the evolution of fins and replacement of the bony plates with several types of dermal scales. The evolution of reptiles saw a major transformation of the integument, with the epidermis becoming the protective outermost layer, from which the scales arose, while the dermis lay below it. The biological significance of the newly-evolved β-keratin in reptilian scales, among the toughest natural materials known, is discussed in the context of its major contribution to the great success of reptiles and to the evolution of feathers and avian flight. The dermis in many vertebrates is strengthened by layers of oppositely oriented cross-fibres, now firmly entrenched as a design principle of biomechanics. Throughout the book conventional ideas are discussed and a number of new hypotheses are presented in light of the latest developments. The long evolutionary history of vertebrates indicates that the significance of the Darwinian concept of “survival of the fittest” may be overstated, including in our own mammalian origins and that chance often plays a major role in evolutionary patterns. Extensive illustrations are included to support the verbal descriptions. Professor Theagarten Lingham-Soliar is in the Department of Life Sciences at the University of KwaZulu-Natal.
