It has nerve-ganglia and a spinal cord long before it 

 has a brain. It has a notochord before it has a spinal 

 cord. It feeds before it has a stomach or a mouth; it

 tubular body- wall of worms; the shoulder and thigh 

 muscles were developed by fish to move the fins. 

 Arms and legs grew stronger through a long series of 

 generations of amphibians and reptiles. Hands and 

 fingers were developed by arboreal animals. These 

 mature in the same order in the human child to-

 trunk outward to the fingers or downward to the 

 toes. The muscles of the neck are very old, those of 

 the jaws are younger, those of the tongue and lips 

 and the muscles of expression are younger still. 



"Late in Tertiary times primitive man or his 

 anthropoid ancestor forsook the trees and lived 

 upon the ground." 



The gigantic forms in animal and in vegetable life 

 largely gave place to lesser forms in both spheres. 

 With the advent of the lesser forms in animal Me 

 came an increase in the size of the brain, muscular 

 power declined and a new kind of power, nerve 

 power, came in. Yet not in all forms; the horse went 

 up from small to large, so did the elephant, so did 

 man, and a few other forms. 



Size and power seem by no means to have been
