Marine biology
During the Age of Discovery many ships sailed far from home. Captain James Cook went twice around the world and discovered new places. Another person who helped is Charles Darwin, known for the Theory of Evolution. He worked in marine biology. His expeditions aboard the HMS Beagle from 18311836  collected marine organisms. Several other people also made important voyages. Alfred Russel Wallace spent much of his younger life travelling the world and recording the plants and animals he saw.
