<\/a>Darwin began his life as a mediocre student and a young adult with no clear fixed sense of an occupation. After “wasting” his time (Darwin’s word) as a student of medicine and theology, he was invited to sail on H.M.S. Beagle <\/em>as a geologist and naturalist in 1831. He returned in five years as a seasoned collector and recorder of scientific information. His own research, along with the work of Lyell, Herschel<\/a>, and Whewell, led him directly into the species question, then being widely debated by naturalists and others. The evidence of Darwin’s voyages and observations made it seem impossible that existing creatures were not directly related to previously existing forms of life and thereby to each other. So traumatized was Darwin by the implication of his emerging theory, that he refused to publish his findings for two decades. The letter in which he may have committed his conclusion to paper for the first time conveys Darwin’s clear sense of the power of his insight: “I am almost convinced (quite contrary to opinion [sic] I started with) that species are not (it is like confessing a murder) immutable” (January 1844).<\/p>\nThe budding naturalist Charles Darwin took a journey that led him to become perhaps the most famous scientific traveler of the past two centuries. His four year voyage, the practical purpose of which was mapping and harbor identification for the British navy, also produced a volume with a title that combines the genres of travel narrative and natural history: Journal of Researches into the Natural History and Geology of the Countries Visited during the Voyage Round the World of H.M.S. \u2018Beagle’ <\/em>. Darwin had originally been invited on the voyage merely as a companion to the captain, but once his careful journals and observations began to circulate on shipboard, he was retained for the entire journey in the role of naturalist and textual recorder of the expedition. In Darwin ‘s case, his life as a natural scientist literally began only when he became a traveler.<\/p>\n Here is Darwin arriving in the Gal\u00e1pagos: \u201cthe Beagle sailed round Chatham Island , and anchored in several bays. One night I slept on shore on a part of the island where black truncated cones were extraordinarily numerous: from one small eminence I counted sixty of them, all surmounted by craters more or less perfect. The greater number consisted merely of a ring of red scoriae or slags cemented together: and their height above the plain of lava was not more than from fifty to a hundred feel: none had been very lately active\u201d (1890 [1845], 399-400). Travel writing perhaps, but clearly the travel writing of a geologist. Like many travel narratives, Darwin draws the logic of his descriptions through comparison; he relates details we will not know to details we may know well:<\/p>\n Most of the organic productions are aboriginal creations found nowhere else; there is even a difference between inhabitants of different islands; yet all show a marked relationship with those of America, though separated from that continent by an open space of ocean, between 500 and 600 miles in width. The archipelago is a little world within itself, or rather a satellite attached to America, whence it has derived a few stray colonists, and has received the general character of its indigenous productions. (403)<\/p><\/blockquote>\n But of course, Darwin is more struck by the differences he notes between plants and animals on these volcanic rocks and on the mainland. His continued emphasis on these differences leads him toward the greatest observation he would make on these travels: \u201cHence, both in space and time, we seem to be brought somewhat near to that great fact B that mystery of mysteries\u2014the first appearance of new beings on earth\u201d (403). Evolution through natural selection will prove to be the only explanation for these otherwise unexplainable differences among similar species in different environments. The traveler becomes a scientist at precisely that moment when he can draw a valid conclusion from the varied details of his numerous observations.<\/p>\n When Darwin concludes the narrative of trip around the world, he lists several motives for and benefits of such travel and such travel writing: pleasure derived from new scenery (\u201cnone exceed in sublimity the primeval forests undefaced by the hand of man\u201d [534]); the sight of indigenous peoples \u201ccould our progenitors have been men like these?\u201d [535]), spectacles of nature (\u201cthe Southern Cross, the cloud of Magellan . . . the waterspout\u2014the glacier . . . the lagoon island . . . an active volcano\u201d [536]), love of the outdoors (\u201cliving in the open air, with the sky for a roof and the ground for a table\u201d [536]), and the satisfactions of adding to human knowledge of the globe (\u201cthe map of the world ceases to be a blank\u201d [536]). It is not surprising that Darwin adds one benefit from world travel that now rings with a hollow thud in our own twenty-first century ears: \u201cthe march of improvement, consequent on the introduction of Christianity throughout the South Seas .. . . [and] the philanthropic spirit of the British nation . . .It is impossible for an Englishman to behold these distant colonies without a high pride and satisfaction. To hoist the British flag seems to draw with it as a certain consequence, wealth, prosperity, and civilization\u201d (537). Even Charles Darwin’s ideological underpinnings can place him at a far remove from our own postcolonial sensibilities. In conclusion, however, he says that \u201cnothing can be more improving to a young naturalist than a journey in distant countries\u201d (537).<\/p>\n Many earlier writers and investigators (including Darwin’s own grandfather Erasmus<\/a>) had suggested the possibility of organic evolution. No one before Darwin provided an explanation for the means by which evolution took place. Natural selection was not a complete idea as expressed by Darwin; his version lacked the insights of Mendelian genetics which would not be available to the general scientific community until 1900. Nevertheless, Darwin’s powerful ideas have affected all those who have sought to understand nature from his own day until our own.
