2IO THE ANTIQUITY OF MAN 
The true picture is very different. We have to conceive 
an ancient world in which the family of mankind was 
broken up into narrow groups or genera, each genus 
being again divided into a number of species — much as 
we see in the monkey or ape world of to-day. Then out 
of that great welter of forms one species became the 
dominant form, and ultimately the sole surviving one — 
the species represented by the modern races of mankind.
