Leighton is a scientific publication likely written in the early 20th century. The text explores the foundational concepts of embryology, detailing the processes of reproduction and the cellular origins of individual organisms. It aims to shed light on the importance of understanding embryonic development for various fields, including education, parenthood, and social reforms. The opening of the book introduces the core questions surrounding embryology, emphasizing its significance and relevance to every educated individual. Dr. Leighton defines embryology as the branch of biology concerned with the formation and development of embryos, highlighting the knowledge gap that has historically shaped treatment and perspectives toward the young. He outlines key concepts like the cell's role in creating new individuals and introduces fundamental ideas about reproduction, emphasizing the continuity of germ-plasm and its critical implications for understanding heredity and individual development. The discussion sets the stage for deeper exploration into the processes of fertilization, early cell division, and the complexities of human development in subsequent chapters.
