THE MOST ANCIENT REMAINS OF MAN 
CONCLUSION 
Accounts given in the last four chapters by no means 
cover all the finds of ancient human remains made thus 
far in various parts of 
the globe. But they 
cover briefly the more 
important discoveries 
and will perhaps suf- 
fice to make clear the 
nature of the steadily 
growing evidence 
upon which is based 
our knowledge of the 
remote past of man- 
kind. 
We have now dis- 
cussed the physical 
side of man’s develop- 
ment including both 
the world in which he 
found himself and 
also his own _ bodily 
structure. In doing 
this, we have pro- 
ceeded step by step 
from the known to 
the unknown, from 
the comparatively re- 
cent past back into 
an antiquity almost 
inconceivably remote

man or manlike creatures are indistinguishable from the 
anthropoids. The table on page 165 summarizes this 
panorama of man’s physical history.
