The wide range of far off destinations opened Darwins mind to how this all fitted together. In 1831, the Beagle sailed for South America where she completed extensive surveys, returning via New Zealand in 1836. His theory of evolution by natural selection, now the unifying theory of the life sciences, explained where all of the astonishingly diverse kinds of living things came from and how they became exquisitely adapted to their particular environments.ĭarwin served as an unpaid naturalist on a science expedition on board HMS Beagle. Charles Darwin, born in Shrewsbury, Shropshire, England, established that all species of life have descended over time from common ancestors.ĭarwin ( 12 February 1809 –19 April 1882) published his theory of evolution with compelling evidence in his 1859 book On the Origin of Species ![]()
