VERY EARLY DARWIN INVESTIGATION OF THE RACES OF MAN. In 1834 Darwin heard that head lice vary among the races of man while on the voyage of the Beagle. In his Beagle zoological diary he wrote, “Mr Martial, a surgeon of an English Whaler assures me that the Lice of the Sandwich Islanders … if they strayed to the bodies of the English in 3 or 4 days died … If these facts were verified their interest would be great.— Man springing from one stock according his varieties having different species of parasites.— It leads one into many reflections.” Intrigued by the implications of this observation, Darwin began collecting specimens for further research.
