"Hormones and Heredity" by J. T. Cunningham is a scientific publication written in the early 20th century. It explores the relationship between hormonal influences and evolutionary adaptations, as well as modern genetic theories surrounding heredity and mutations. The author aims to clarify misunderstandings and present fundamental facts regarding hormones and their implications for adaptation and species evolution. The opening of the volume provides a preface where the author outlines his objectives, emphasizing the need to elaborate on the effects of hormones and their connection to heredity through Mendelian principles. The text expresses concern over the limited dissemination and comprehension of his previous work, arguing for the importance of presenting both historical and contemporary perspectives on hormonal influence in evolutionary biology. Additionally, the introduction serves as a historical survey of theories regarding chemical influences in heredity, setting the stage for the detailed examination of adaptation, classification, and the role of hormones in subsequent chapters.
