INTELLIGENCE, POWER, 



Just as we found a higher development of the energy 

 system in a thoroughbred horse than in the Arabian or the 

 work horse and in the cold-adapted Shetland pony than 

 in the tropic-adapted ass, so we found a higher development 

 of the brain-heart-thyroid-adrenal-sympathetic system in 

 a racing grey-hound than in a petted house dog. 



With the exception of the thoroughbred horse and the 

 greyhound, all the domestic animals, as well as all members 

 of the grass- and leaf-eating families, are geared to run the 

 course of destiny, whether it be the chase, the escape, or 

 the long pull of producing milk or meat or eggs for man. The 

 pursuers, the pursued, and the wild animals bred by man 

 to be domestic drones in order to make the long-continued 

 output of energy, have thyroid and adrenal glands that are 

 more nearly balanced. 



It is interesting to compare the means by which cattle 

 and sheep are bred for domestication by man with the 

 means by which antelopes and zebras are "bred" for speed 

 by the lion and other carnivores. 



By taking for his food the slowest-going members of the 

 herd, the carnivore is effecting for the herd what man does 

 in the breeding of domestic animals. The carnivore kills 

 the less fit; man breeds from the most fit. 



If the influence of man were withdrawn overnight from 

 the world, what would be the effect on the domestic animals 

 whose body formula of energy and form has been adapted 

 for food they could not have found in the wild state? The 

 special senses, as well as the brain and the heart of domestic 

 animals, have so deteriorated that the chance of escape 

 from the pack of dogs and wolves would be seriously
