查尔斯达尔文在19世纪30年代早期的H.M.S.五年航行比格尔已成为传奇，因为这位聪明的年轻科学家在异国风情旅行中所获得的见解极大地影响了他的杰作，即“论物种的起源”。达尔文实际上并没有在皇家海军舰船上环游世界时制定他的进化论。但他遇到的外来植物和动物挑战了他的思想，并使他以新的方式考虑科学证据。从他在海上五年回到英国后，达尔文开始写一本关于他所见过的多卷书。他关于比格尔航行的着作于1843年结束，距“物种起源”出版前十五年。 H.M.S. Beagle今天因为与查尔斯·达尔文的关系而被人们记住，但是在达尔文进入画面之前几年，它已经进行了漫长的科学任务。比格尔是一艘载有十门大炮的战舰，于1826年航行，探索南美洲的海岸线。当船长陷入萧条时，这艘船发生了不幸的事件，这可能是由于航行的孤立造成的，并且自杀了。中尉罗伯特·菲茨罗伊接管了比格犬，继续航行，于1830年将船安全返回英格兰。菲茨罗伊被提升为上尉并命名为第二次航行指挥该船，这是为了环绕地球进行探险。南美洲海岸线和南太平洋。菲茨罗伊想出了一个带有科学背景的人，他可以探索和记录观察结果。 FitzRoy计划的一部分是，一个受过教育的平民，被称为“绅士乘客”，将成为船上的好公司，并将帮助他避免似乎注定了他的前任的寂寞。英国大学的教授们进行了调查，达尔文的一位前教授提议他在比格尔号上担任此职位。在1831年在剑桥进行期末考试后，达尔文花了几周的时间在威尔士进行地质考察。他原本打算回到剑桥去接受神学训练，但教授John Steven Henslow邀请他加入Beagle的一封信改变了一切。达尔文很高兴加入这艘船，但他的父亲反对这个想法，认为这是蛮干的。其他亲戚否则说服达尔文的父亲，并且在1831年秋天，22岁的达尔文准备离开英格兰五年。
Charles Darwin’s five-year voyage in the early 1830s on H.M.S. Beagle has become legendary, as insights gained by the bright young scientist on his trip to exotic places greatly influenced his masterwork, the book “On the Origin of Species.” Darwin didn’t actually formulate his theory of evolution while sailing around the world aboard the Royal Navy ship. But the exotic plants and animals he encountered challenged his thinking and led him to consider scientific evidence in new ways. After returning to England from his five years at sea, Darwin began writing a multi-volume book on what he had seen. His writings on the Beagle voyage concluded in 1843, a full decade and a half before the publication of “On the Origin of Species.” H.M.S. Beagle is remembered today because of its association with Charles Darwin, but it had sailed on a lengthy scientific mission several years before Darwin came into the picture. The Beagle, a warship carrying ten cannons, sailed in 1826 to explore the coastline of South America. The ship had an unfortunate episode when its captain sank into a depression, perhaps caused by the isolation of the voyage, and committed suicide. Lieutenant Robert FitzRoy assumed command of the Beagle, continued the voyage, and returned the ship safely to England in 1830. FitzRoy was promoted to Captain and named to command the ship on a second voyage, which was to circumnavigate the globe while conducting explorations along the South American coastline and across the South Pacific. FitzRoy came up with the idea of bringing along someone with a scientific background who could explore and record observations. Part of FitzRoy’s plan was that an educated civilian, referred to as a “gentleman passenger,” would be good company aboard ship and would help him avoid the loneliness that seemed to have doomed his predecessor. Inquiries were made among professors at British universities, and a former professor of Darwin’s proposed him for the position aboard the Beagle. After taking his final exams at Cambridge in 1831, Darwin spent a few weeks on a geological expedition to Wales. He had intended to return to Cambridge that fall for theological training, but a letter from a professor, John Steven Henslow, inviting him to join the Beagle, changed everything. Darwin was excited to join the ship, but his father was against the idea, thinking it foolhardy. Other relatives convinced Darwin’s father otherwise, and during the fall of 1831 the 22-year-old Darwin made preparations to depart England for five years.
