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.’
