Charles Darwin 
Origin of Species and the Voyage of the Beagle [EPUB ebook] 

Discover Charles Darwin’s most important ideas… When the eminent naturalist Charles Darwin returned from South America on board the H.M.S Beagle in 1836, he brought notes and evidence that would form the basis of his landmark theory: that species evolve by a process of natural selection.

It also sparked a fierce scientific, religious and philosophical debate that still rages today. WITH AN INTRODUCTION BY DARWIN’S GREAT-GREAT-GRANDDAUGHTER, RUTH PADEL
