Before Adam is a novel by Jack London, published in 1907. It is the story of a boy who dreams he lives the life of an early hominid Australopithecine.
The story offers an early view of human evolution. The majority of the story is told through the eyes of the boy's hominid alter ego, one of the Cave People. In addition to the Cave People, there are the more advanced Fire People, and the more animal-like Tree People.
Other characters include the hominid's father, a love interest, and Red-Eye, a fierce "atavism" that perpetually terrorizes the Cave People. A sabre-cat also plays a role in the story.
Jack London (1876-1916) was an American author, journalist, and social activist. He was a pioneer in the then-burgeoning world of commercial magazine fiction and was one of the first fiction writers to obtain worldwide celebrity and a large fortune from his fiction alone.
London's most famous novels are The Call of the Wild, White Fang, The Sea-Wolf, The Iron Heel, and Martin Eden.
