RE:A new word for today Speaking of chimera, my father experimented on Chimera calves before performing Canada's first lung transplant on September 29, 1965, two years before Christian Bernard did his heart transplant I'm South Africa.
They were completely identical because they shared a placenta.
It was the fourth lung transplant in the world, and the first considered successful, because the volunteer subject patient didn't need mechanical aid such as an iron lung to breath post-op.
He only survived two days because back then there were no anti-rejection drugs.
