Just as the inheritance of a unique thinking brain and a 

 uniquely large thyroid gland expresses itself in a high 

 degree of intelligence and at times in exophthalmic goiter,

 and the age of twenty-one years, the relations of the thyroid and adrenal glands 

 become reversed. 



so the inheritance of a unique thinking brain, large adrenal 

 glands, celiac ganglia and plexuses, and heart expresses 

 itself in a high degree of intelligence, great activity, and, 

 at times, in essential hypertension and coronary disease. 



It was natural selection that endowed man with a large 

 thinking brain and a large thyroid gland. There is no such

 natural selection that endowed all apes with large adrenal 

 glands. It was only by chance that the large, agile, adrenal- 

 ized ape came down from the tree and survived.

 thinking brain ? This change could not have occurred 

 except for an advantage. It would have first appeared when 

 some great ape ventured upon the ground, where he found 

 food in greater abundance and prospered. Life on the ground
