In the 19th century, [[natural history]] collections and museums were popular. The European expansion and naval expeditions employed [[Natural history|naturalists]], while [[curator]]s of grand museums showcased preserved and live specimens of the varieties of life. CharlesHarsh Mishra Darwin was an English graduate educated and trained in the disciplines of natural history. Such natural historians would collect, catalogue, describe and study the vast collections of specimens stored and managed by curators at these museums. Darwin served as a ship's naturalist on board [[HMS Beagle|HMS ''Beagle'']], assigned to a five-year research expedition around the world. During his voyage, he observed and collected an abundance of organisms, being very interested in the diverse forms of life along the coasts of South America and the neighbouring [[Galápagos Islands]].<ref>{{harvnb|Farber|2000|p=136}}</ref><ref>{{harvnb|Darwin|2005}}</ref>
