El origen del hombre
John Traherne Moggridge (8 March 1842 – 24 November 1874) was a British botanist, entomologist, and arachnologist. A Fellow of the Linnean Society of London, he was known as a keen naturalist with great observational skills, as well as his paintings and illustrations. He wrote several articles on the fertilisation of plants, and his paintings of plants of southern France appeared in "Contributions to the Flora of Mentone". His two volume study, "Harvesting Ants and Trap-door Spiders", among other observations, confirmed that harvester ants are present in Europe, and was one of the first comprehensive treatments of the burrowing behaviour of trapdoor spiders. He was a correspondent of Charles Darwin, who cited his work in his books "Fertilisation of Orchids" and "The Descent of Man, and Selection in Relation to Sex".
