The child was dead. It was an attempt to save her life. She lasted twenty days. Christian Barnard's first heart transplant lasted......18 days.
dead = "dead"
The child was alive and could quite possibly have lived longer using a chimp rather than a baboon heart.
You seem to have an odd definition of dead, even in quotes.
When Debakey (sp, i'm sure, is wrong) got his early "success," there was a lot of overenthused overreaching. The evos think this is a poster child thing, but it could have been no more than a flippant remark made by a professional. I'll do some reading about Baby Fae, though, and I'll bet there were some ideas (wrong ideas) about the operation that had nothing to do with the Descent of Man.
