As I said, you did not address my quote, and you still haven't.
As for pigs... show me a pig solid organ transplant or get off it.
The pig tissues you refer to are dead tissues.
So, how do you feel about Dr. Bailey's statements vis a vis his choice of baboon rather than chimp heart?
As I said, yes I did. Again, So? The choice was not by one individual. The heart was not rejected. The baby lasted longer on the baboon heart than the first human heart transplant. And much longer than any chimpanzee transplant that I know of. So what does evolution have to say about this?

The procedure of transplanting animal organs into humans, or xenotransplantation, became a reality in 1964 (before the first human-to-human heart transplant) with the first chimpanzee-to-human heart transplant. While this pioneering procedure was ultimately unsuccessful (the chimpanzee heart was not large enough to sustain the circulatory needs of the human patient) it promised a steady supply of organs -- if the right species could be found. Today, most xenotransplantation research focuses on pigs, since the size and output of an average-sized pig heart is very close to that of a human heart. Unfortunately, rejection is even more likely in cross-species transplants. And drugs that can keep a patient from rejecting a pig heart render that patient's body almost completely defenseless in the event of infection.
