pools 5 as much power has been needed to raise the one 

 as the other, and there is no a priori reason why the 

 forces which have grafted on the insect type the 

 features and powers of an intelligent bee should not 

 go on to work the same type into something possessing 

 powers and qualities as full, as great, and as varied as 

 those which we ourselves possess/ 



The vertebrate type itself is, moreover, subdivided 

 into many subordinate types, each of which goes along 

 its own lines of development and differentiation, so 

 that there is no trace of any single and general pro- 



gression towards the perfection of that mammalian 

 can rightfully ck: branch, of which Man forms the head and crown. As

 absolute neccs one another and from the general vertebrate plan. Whilst 



amongst Birds also, such specializations of the respi-

 the conditions had been suitable, the progenitors of the 

 quadrumanous race might have given rise to all that has 

 appeared along this line of development far back in the 

 depths of geologic time — and wholly irrespective of the
