THE EVOLUTION OF MAN 



ary mammals always have this very characteristic 

 projection. They evidently belonged to a group 

 of mammals whose last living representatives are 

 the present-day marsupials. These bones are 

 also found in Africa, Asia and Europe, proving 

 that this race of marsupials formerly inhabited 

 the entire earth. 



Under these conditions the assumption was 

 justified that this primitive group of mammals 

 represented the most ancient type, from which 

 the tertiary archetype of the higher side lines 

 might have developed. In that case, they once 

 more show us another mile stone in the upward 

 march of disguised man a marsupial man as a 

 contemporary of the Ichthyosaurian. This gen- 

 eral conclusion is confirmed by a good many de- 

 tails. 



Marsupials owe their name to a fact, which 

 every child notices in the kangaroos of our zoo- 

 logical gardens, that is to say, the female carries 

 its young, which is born in an immature state, 

 for a while in a protecting fold of its skin, the 

 so-called pocket. In this pocket the young finds 

 the milk-nipples which it uses in suckling as
