Nonetheless, over the course of the five-year journey around the globe in often hard and hazardous conditions, Darwin would make observations and gather samples that would form the basis of his revolutionary theories about the origin of species and natural selection.

Drawing on a rich range of revealing letters, diary entries, recollections of those who encountered him, and Darwin's and FitzRoy's own accounts of what transpired, Diana Preston chronicles the epic voyage as it unfolded, tracing Darwin's growth from untested young man to accomplished adventurer and natural scientist in his own right.
