Plate from 'The Zoology of the Voyage of HMS Beagle', published in London, 1839-1843, and edited by the British originator of evolutionary theory Charles Darwin (1809-1882). Darwin wrote of these animals, common to both East and West Falkland, that 'They have been observed to enter a tent, and actually pull some meat from beneath the head of a sleeping seaman.' Darwin was naturalist on 'HMS Beagle' during its voyage of 1832-1836, the purpose of which was to make a scientific survey of the South American waters. Darwin's observations contributed to his discovery of the principle of natural selection of heritable variation as the cause of evolution. His famous work, 'On the origin of species by means of natural selection', was published in 1859.
