Which paragraphs from The Autobiography of Charles Darwin most effectively develop Darwin's claim that the voyage of the "Beagle" was the most important event in his life?

The event now known as "the voyage of the Beagle" comprises Charles Darwin's circumnavigation as ship's naturalist on the second of three surveying voyages by H. M. S. Beagle; the writings published as his first book, the Journal of Researches; and the genesis of his theory of evolution by natural selection. Writing between regimes of world-knowledge, Darwin mediates scientific observation through the language of aesthetics, and seeks to understand the convergence of disparate scales of geological and human history.
