Monogenism or sometimes monogenesis is the theory of human origins which posits a common descent for all humans. The negation of monogenism is polygenism.This issue was hotly debated in the Western world in the nineteenth century, as the assumptions of scientific racism came under scrutiny both from religious groups and in the light of developments in the life sciences and human science.
The theory of degeneration found its first detailed presentation in the writings of Bénédict Morel (1809–1873), especially in his Traité des dégénérescences physiques, intellectuelles et morales de l'espèce humaine (Treatise on Degeneration of the Human Species) (1857). This book was published two years before Darwin's Origin of ...
Life history theory has provided new perspectives in understanding many aspects of human reproductive behavior, such as the relationship between poverty and fertility. [43] A number of statistical predictions have been confirmed by social data [ citation needed ] and there is a large body of scientific literature from studies in experimental ...
Human behavior is the potential and expressed capacity (mentally, physically, and socially) of human individuals or groups to respond to internal and external stimuli throughout their life. Behavior is driven by genetic and environmental factors that affect an individual.
There is no single generally accepted model for the origin of life. Scientists have proposed several plausible hypotheses which share some common elements.

The history of evolutionary psychology began with Charles Darwin, who said that humans have social instincts that evolved by natural selection.Darwin's work inspired later psychologists such as William James and Sigmund Freud but for most of the 20th century psychologists focused more on behaviorism and proximate explanations for human behavior.

Human ethology is the study of human behavior. Ethology as a discipline is generally thought of as a sub-category of biology, though psychological theories have been developed based on ethological ideas (e.g. sociobiology, evolutionary psychology, attachment theory, and theories about human universals such as gender differences, incest avoidance, mourning, hierarchy and pursuit of possession).
