Douglas Edvard Melin (4 October 1895 – 29 March 1946) was a Swedish zoologist[1][2] and athlete.
[1] He competed in the men's standing long jump at the 1912 Summer Olympics.
[1] Melin was an all-sided zoologist who got his education at the Uppsala University and spent his career there.
In 1923–26 he led an expedition to Brazil and Peru, which resulted in a large number of zoological specimens as well as ethnographic and cartographic observations.
Melin was skeptical about Darwin's theories, which led to his isolation as a scientist.
