HMS Beagle. A Cherokee-class brig-sloop, launched from the Woolwich Dockyard. She was adapted as a survey barque and took part in three expeditions, the second of which was the voyage on which the young Charles Darwin began to form his theory of evolution.:
Robert FitzRoy (5 July 1805 – 30 April 1865) achieved lasting fame as the captain of HMS Beagle during Charles Darwin's famous voyage, and as a pioneering meteorologist who made accurate weather forecasting a reality. He was an able surveyor and hydrographer and served as Governor of New Zealand from 1843 to 1845.
Jean-Baptiste Pierre Antoine de Monet, Chevalier de la Marck (1 August 1744 – 18 December 1829), often known simply as Lamarck, was a French naturalist. He was a soldier, biologist, academic, and an early proponent of the idea that evolution occurred and proceeded in accordance with natural laws. http://biodiversitylibrary.org/creator/12
