Which is it, if either, and if it is not the pig why does it seem that pigs are the animals of choice for human heart transplants?
Pig hearts are closest re: size and output. But pigs aren't the only animal donors. A chimp to human transplant was completed in 1964. (It was unsuccessful -- chimp hearts are too small.)
Most human heart transplants, however, are from human donors. And by most, I mean 99.99%.
A doctor in India got caught using pig hearts in 1997. He was arrested and jailed. Nature. 1997 Jan 30;385(6615):378.
i believe that our closest living relative based on genetics is the ape is this correct? i also have heard that it may be the pig.

If I may, Louie, both of your questions are SO easily answered via google. Is there any particular reason you chose to ask them here rather than look for the answer yourself?
