Time Slave
Time Slave is a 1975 hybrid of historical fiction and science fiction by John Norman. In this book, Norman presents his personal theories of human evolution, exemplified by the case of a modern 20th century woman sent back in time 20,000 years or more; he mourns the loss of human evolutionary fitness and distortion of "natural" social relations which, in his view, occurred when farming spread and farmers squeezed hunter/gatherers to the ecological margins. Time Slave features Norman's social philosophy of male-dominance, and expresses an unexplained connection between female sexual subordination and the speeding up of the development of space travel.
