This book is a vivid and exciting travel memoir as well as a detailed scientific field journal covering biology, geology, and anthropology that demonstrates the author’s keen powers of observation, written at a time when Western Europeans were still discovering and exploring much of the rest of the world. The author's five-year journey took him from the coasts of South America, Australia, and Africa to the South Pacific islands, during which he collected and documented the natural history of these areas. The voyage and the specimens he brought back would later form the basis for his famous theory of evolution.

"Alive" is a gripping true story of survival, recounting the harrowing ordeal of a Uruguayan rugby team whose plane crashes in the Andes mountains in 1972. Stranded for over two months in the harsh, freezing wilderness, the survivors face unimaginable hardships, including avalanches, starvation, and the devastating decision to resort to cannibalism to stay alive. The book is a testament to the strength of the human spirit and the will to survive against all odds.
