to exemplify this greater male variability in humans, darwin also cites some observations made by his contemporaries. for example, he highlights findings from the novara expedition of 1861–67 where "a vast number of measurements of various parts of the body in different races were made, and the men were found in almost every case to present a greater range of variation than the women" (p. 275). to darwin, the evidence from the medical community at the time, which suggested a greater prevalence of physical abnormalities among men than women, was also indicative of man's greater physical variability.
