Charles Darwin's discussions of gender, particularly in his work "The Descent of Man," reflect the scientific views of his time, which included differences attributed to gender. While Darwin acknowledged the roles that both sexes played in evolution and reproduction, he also expressed views that suggested intellectual and physical differences between males and females.
Specifically, Darwin asserted that, on average, males tend to have greater physical strength and that there were differences in intellectual capabilities, often positing males as superior. This perspective has been critiqued and challenged by modern scholarship, which emphasizes the value and capabilities of both sexes and contests the notion of inherent superiority based on gender.
In summary, from Darwin's writings, the idea that "females are inferior to males intellectually and physically" aligns with some of his views, although his overall discussion is nuanced and includes observations about the roles of both sexes in evolutionary contexts.
