130 CONTROLLED NATURAL SELECTION 
order to make themselves easily visible to 
their enemies, other tribes. It must be re- 
membered that savage man delighted in fight- 
ing; he did not seek always to take his 
enemy unawares, but rather desired to meet 
him in fair and open battle. 
There appears to be little in civilisation, 
to which this Theory can be applied. The 
present-day demand of the female for some 
recognition of her great value to the race, 
may possibly be a cry of Nature, a call from 
out the past. 
Human society illustrates the conclusions 
which were arrived at in Chapter IV by show- 
ing that competition does not lead to advance- 
ment, which is best gained by environmental 
differentiation or specialisation. 
Finally, it may be said that species rid them- 
selves of males in the following ways : 
1. Sacrifice them to enemies. 
2. Cause them to destroy one another. 
3. Themselves destroy them. 
4. Or control their production.
