Xenotransplantation is using nonhuman animal organs in transplantation. Many people are against this practice. What would be the best argument for why xenotransplantation should be accepted? A. There are more people on transplantation lists than donor organs so xenotransplantation can save people’s lives
B. People on transplantation lists are not treated equally in that some are moved to the top of the list
C. There are no antigens on the surface of nonhuman animals so there would be no rejection
D. More organs can be extracted from nonhuman to accommodate more recipients

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."

the answer is 95 degrees

1. is geographic distribution

2 is increasing complexity

3 is transitional forms
