Although they share around 95% of their DNA with us, compared to 98.9% for the pygmy chimp, pigs are considered to the most compatible animals for potential organ transplants into humans. This is because pig organs are more similar in size to human organs, and there is a risk of AIDS from primate organs. Also, there are more ethical problems with the use of primates compared to pigs - eg, in the western world we rear pigs to eat, but not monkeys.
