Where and when did man make his first appearance on this earth?

The object of this book is to bring before the public such further facts and values regarding the evolution of man. After studies Churchwood made during many years, he is now fully convinced that the hitherto preconceived ideas of many scientists regarding the origin of the human race, both as to place and date, are erroneous, and evidence will be brought forward to prove that the human race did not originate in Asia, but in Africa.
