Charles Darwin-one of the men who changed the world

Naturalist Charles Darwin established the theory of revolution. He began forming his ideas when he served as official naturalist on a world voyage on HMS Beagle (1831-36) and spent the rest of his life back in England developing them .when his famous book origin of species by means of natural selection was published in 1859 there were violent reactions against it. Darwin challenged the bible’s account of creation and explained that human beings are descended from an ape-like ancestor .another English naturalist Alfred Russell Wallace, independently developed very similar ideas at the same time as Darwin.
