In Darwin's Image

Life''s origin provides the point of departure for this book. After developing rules that all life must follow we review life''s layered progression from bacterium to nucleated cell to multicellular organism showing how inadvertent information transfers and accidental mergers of desperately competing organisms brought about important advances. As we examine the efficiencies gained through cell specialization it becomes clear why a reorganization of specialized cells into complex organ systems brought additional reproductive advantages. Our overview of human biology concludes with evolutionary insights into human sexuality and embryo development. The facts reported herein are up-to-date and widely accepted. They have been garnered from many scientific fields and a lifetime of personal and professional experiences. So even if you already understand a lot about human biology my report on how evolution underlies human form and function should interest and entertain you. As for those with little previous exposure to human physiology or modern Evolution Theory this book can help bring you up to speed.
