Taboo and genetics : $b A study of the biological, sociological and psychological foundation of the family
"Taboo and Genetics" by Melvin M. Knight, Ph.D., Iva Lowther Peters, Ph.D., and Phyllis Blanchard, Ph.D., is a scientific publication written in the early 20th century. This work investigates the biological, sociological, and psychological foundations of the family, focusing on how scientific advancements in biology have led to a re-evaluation of traditional sociological views regarding sex and family dynamics. The opening of the text serves as a preface, outlining the authors' intention to revisit and challenge established theories about sex and social structures, particularly in light of recent biological findings. They indicate a need to dissect the outdated "gynæcocentric" theory that dominated sociological thought, acknowledging its inaccuracies while proposing a multidisciplinary approach to understanding sexual relationships. This includes examining the historical influence of sex taboos as well as integrating insights from modern psychology and ethnology to provide a comprehensive overview of how these factors converge to impact family life and societal norms today.

The genetic and the operative evidence relating to secondary sexual characters
"The Genetic and the Operative Evidence Relating to Secondary Sexual Characters" by T.H. Morgan is a scientific publication written in the early 20th century. This work delves into the genetic and physiological aspects of secondary sexual characteristics in birds, particularly focusing on the Sebright bantam and other fowl as subjects for analysis. It covers various experiments and findings related to plumage differences between hen-feathered and cock-feathered males, exploring how these traits are influenced by factors such as heredity and endocrine signaling. The opening of the book sets the stage for an in-depth study of the genetic mechanisms at play in determining secondary sexual characteristics. It begins with a discussion of the existence of two male types within certain poultry breeds and introduces the author's experimentation with castrating hen-feathered Sebrights to observe changes in plumage. Morgan recounts his observations regarding the physical alterations in feathering post-operation, revealing insights into the relationship between the gonads and plumage expression. This portion establishes not only the methodology and initial findings but also hints at the broader implications for understanding sexual differentiation in birds.
