Moral Debate: Procedure Risks Making Monkeys More Humanlike
 The insertion of human stem cells into monkey brains runs a "real risk" of altering the animals' abilities in ways that might make them morally more like us, scientists said today. A panel of 22 experts -- including primatologists, stem cell researchers, lawyers and philosophers -- debated the possible consequences of the technique for more than a year. While the group agrees it is "unlikely that grafting human stem cells into the brains of non-human primates would alter the animals' abilities in morally relevant ways," the members "also felt strongly that the risk of doing so is real and too ethically important to ignore." In the case of Alzheimer's research, for example, grafting human stem cells into a monkey brain would be designed to reinstate lost memory function, but "we cannot be certain that this will be the only functional result," the report concludes. There was "considerable controversy" within the group, which disagreed on whether such experiements, some already underway, should proceed. {SNIP} Posted by: BigEd 2005-07-14 |
