Comments on Dr. Bernard's Talk The atherosclerosis Dr. Klaper described as slithery, greasy guck has calcified and turned into the hard substance described by Dr. Barnard.
Dr. Barnard has said that we humans have been designed by Nature to be herbivores. Readers that believe that only Intelligence can do any designing might want to go back to Genesis, Chapter One (verse 29, RSV):
“And God said, ‘Behold, I have given you every plant yielding seed which is upon the face of all the earth, and every tree with seed in its fruit; you shall have them for food.’”
No contradiction here.
