I found this from Darwin's book:
"This was the great adventure of Charles Darwin's life. Indeed, it would have been a great adventure for anyone--tracking condor in Chile, surviving the great earthquake of 1835, riding across country on horseback in the company of gauchos, watching whales leaping skyward off Tierra del Fuego, hunting ostriches with a bolo, discovering prehistoric fossils and previously unknown species, and meeting primitive peoples such as the Fuegians.
