Evolutionary Zoology is a sub-field of zoology concerned with the origin of species from a common descent, and descent of species; as well as their change, multiplication, and diversity over time. Handbook of Evolutionary Zoology talks of time scale and events of evolution and goes on to deal with the origin and evolution of life from protozoans to vertebrates. Chapters devoted to the theories and examples on evolution of advanced vertebrates like man, also venture into the philosophical side of evolution, development, survival and natural selection, which make the subject all too meaningful and closer to the real life. Scientific and metaphysical theories on origin and the evolution of creatures lead to the anatomical and fossil evidences on the evolution from protozoa to worms to vertebrates with backbone and brains by way of cells, tissues, and organic correlation and comparison of skeleton and head. Development of mind and the sequence of mental functions and natural selection and the role of environment in evolution of species is discussed afterwards. Chapters also count society as a live component of environment and discuss its impact on future evolution of man as an intelligent species. A valuable reading and referral by all means.
