Certain changes that occurred in the organism 's’ environment allowed it to evolve, survive, and produce offspring with those developed traits. He recorded his findings while aboard the second voyage of H.M.S. Beagle, dating from December 27, 1831 to October 2, 1863 (Leff). Many of his observations would soon come to prove Charles Lyell’s uniformitarianism on the basis of geology, along with his own theory of evolution.
Uniformitarianism, in geology, “the doctrine suggesting that Earth’s geologic processes acted in the same manner and with essentially the same intensity in the past as they do in the present and that such uniformity is sufficient to account for all geologic change” (Britannica). Lyell used James Hutton’s idea of uniformitarianism that the earth was shaped by unseen forces that still exist into the uniformitarianism that the earth was much older than 300 million years (McCarthy).
The H.M.S. Beagle set out on a drizzly morning on December 27, 1831, consisting of seventy-three men to crew the ship. Captain Robert Fitzroy even made his over 400 book library (on the Beagle) available to Darwin, to which his initial readings would be the first volumes of Charles Lyell’s…
