Knowra HMS Beagle HMS Beagle HMS Beagle was a British Royal Navy survey ship that carried Charles Darwin on its second surveying voyage from 1831 to 1836. Its observations helped shape Darwin’s later account of evolution by natural selection.
Second voyage of HMS Beagle : A Royal Navy surveying expedition that circumnavigated the globe from 1831 to 1836. This was the expedition on which Darwin sailed as a naturalist.
Charles Darwin : An English naturalist who developed the theory of evolution by natural selection. He sailed as the expedition's naturalist and collected specimens and observations.
Hydrographic survey : The measurement and mapping of bodies of water, coastlines, and navigational hazards. The Beagle's principal naval task was to survey and chart coastal waters.
On the Origin of Species : Charles Darwin's 1859 book arguing that species evolve through natural selection. Observations collected during the Beagle voyage contributed to the work's development.
First voyage of HMS Beagle : HMS Beagle's 1826–1830 South American surveying expedition, commanded initially by Pringle Stokes and later Robert FitzRoy. It preceded the Darwin voyage and established the ship's surveying role.
Galápagos Islands : An Ecuadorian archipelago in the Pacific Ocean, known for distinctive wildlife and volcanic landscapes. Darwin studied its organisms during the voyage, later using observations from the islands in his evolutionary thinking.
Robert FitzRoy : A British naval officer, hydrographer, and later governor of New Zealand. He commanded the Beagle's second voyage and directed its surveys.
Nautical chart : A map designed for marine navigation, showing coastlines, depths, hazards, and aids to navigation. The expedition's observations were compiled into charts used by later mariners.
Evolution by natural selection : A process in which heritable traits that improve reproductive success become more common across generations. The voyage supplied Darwin with observations that informed his later explanation of this process.
Third voyage of HMS Beagle : HMS Beagle's later surveying expedition to Australia, commanded by John Lort Stokes from 1837 to 1843. It continued the ship's survey work after Darwin's voyage.
