evolution
By the time Darwin returned to England, he was already a celebrity in scientific circles as in December 1835 Hen slow had fostered his former pupil's reputation by giving selected naturalists a pamphlet of Darwin's geological letters.[67] On 2 October 1836 the ship anchored at Goalmouth, Cornwall. Darwin promptly made the long coach journey to Shrews bury to visit his home and see relatives. -

After delays, the voyage began on 27 December 1831; it lasted almost five years. As Fitzroy had intended, Darwin spent most of that time on land investigating geology and making natural history collections, while HMS Beagle surveyed and charted coasts.He kept careful notes of his observations and theoretical speculations, and at intervals during the voyage his specimens were sent to Cambridge together with letters including a copy of his journal for his family. -
evolution 2
Darwin thought of evolution as "descent with modification," a process in which species change and give rise to new species over many generations. He proposed that the evolutionary history of life forms a branching tree with many levels, in which all species can be traced back to an ancient common ancestor. -
Darwin's Observation
Darwin published his theory of evolution with compelling evidence in
his 1859 book On the Origin of Species. By the 1870's, the scientific
community and a majority of the educated public had accepted
evolution as a fact. However, many favored competing explanations which gave only a minor role to natural selection, -
