Interest in organic evolution has increased in recent decades among a wide range of scientists-from astronomers to biochemists. This book provides a scientific account of all core issues pertaining to organic evolution. The information is grouped under twenty four chapters, which will be useful to researchers, scientists and teachers in the field. CONTENTS The Origin of Life; Evidence of Evolution; Lamarckism & Neo-Lamarckism; Darwin's Natural Selection; Sexual Selection; Recapitulation Theory and Extinction; Artificial Selection; Ontogenesis and Kinetogenesis; The Mutation Theory; Colouration and Mimicry; Isolation; Origin of Species; Adaptive Radiation; Cursorial and Fossorial Adaptation; Aquatic Adaptation; Desert Adaptation; Cave and Deep-Sea Adaptations; Volant Adaptation; Scansorial Adaptation; Geographic Distribution; Bathymetric Distribution; The Synthetic Theory of Evolution; Zoogeographical Distribution; Adaptation and Selection; etc.

There are several good reasons to believe that the earliest organisms originated in the sea. The sea contains salts needed for health and growth. Evolution from Rocks consists of eighteen chapters giving an elaborate account of the themes. Researchers, P.G. students, scientists and teachers will find this book of utmost use. CONTENTS Igneous Rocks and Igneous Activity; Metamorphic Rocks and the Continental Crust; Sedimentary Rocks; The Oldest Rocks; Fossilisation; Chemical Fossils; The Oldest Fossils; Geological Distribution; Zoogeographical Distribution; Geographical Distribution; Bathymetric Distribution; Bathymetric Distribution; Evolution by Shull; Vertebrates of Paleozoic Era; Vertebrates of Mesozoic Era; Vertebrates of Mammalian Era; The Origin and Adaptive Radiation of Reptiles; The Origin of Birds; the Origin and Evolution of Mammals; etc.

Pattern of Evolution, consists of eleven chapters, which provides authoritative by facts and figures, on various themes. Certainly, the information contained here will benefit one and all concerned. CONTENTS Introduction; Evolution and Classification; Ontogenetic Evolution; Mendelism and Evolution; Hybrids in Evolution; How does Evolution Differ from Developments; Homeostasis in Evolution; Ageing and Senescence; Evolution of Animals; Evolution of Land Plants; Evolution of the Pent dactyl Limb; etc.

Vertebrates (Chordates) have several diagnostic characters which re absolutely distinctive, separating them sharply from all forms of life. The main contrast between invertebrate and vertebrate animals seems to be that, as a whole the former are static organisms with little or no power of locomotion, while the latter are essentially dynamic. This book presents a scientific story of origin and evolution of vertebrates. The information is grouped under thirteen chapters. CONTENTS Origin of Vertebrates; Origin of Land Vertebrates; Origin of Reptiles; Origin of Dinosaurs; Origin of Birds; Origin of Mammals; Proboscideans; Horses; Camels; South American mammal Radiation; Prosimians; The Evolution of Man; The Gradual Appearance of Man; etc.
