Before Adam by Jack London (1907)

Written in 1906, "Before Adam" is a bit of a departure from London's other novels. Still an adventure novel, this one revolves around the dreams of a young boy, dreams that involve racial memories and the knowledge of his prior existence as a man-like creature named Big Tooth living in prehistoric times. "These are our ancestors, and their history is our history. Remember that as surely as we one day swung down out of the trees and walked upright, just as surely, on a far earlier day, did we crawl up out of the sea and achieve our first adventure on land."Before Adam is a novel by Jack London, serialized in 1906 and 1907 in Everybody's Magazine.[1] It is the story of a man 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 man'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.
