Could ongoing experiments involving the mixing of human and non-human DNA produce monstrous, over-intelligent hybrids down the road? In the U.S., human cells are already being implanted in mouse embryos, so we’ll likely be facing the rats of NIMH, rather than talking chimps who smoke pipes. The Telegraph reports:
Action is needed now, according to a group of eminent experts. Their report calls for a new rules to supervise sensitive research that involves humanizing animals.
“The fear is that if you start putting very large numbers of human brain cells into the brains of primates suddenly you might transform the primate into something that has some of the capacities that we regard as distinctively human..speech, or other ways of being able to manipulate or relate to us.”
Currently research involving great apes, such as chimpanzees, is outlawed in the UK. But it continues in many other countries including the US, and British scientists are permitted to experiment on monkeys.
Prof Baldwin, professor of philosophy at the University of York, recommended applying the “Great Ape Test”. If modified monkeys began to acquire abilities similar to those of chimpanzees, it was time to “hold off”.
In the US, scientists have already implanted human embryonic stem cells – which can develop into any part of the human body – into mouse embryos. The mouse cells rapidly outgrew the human stem cells, so that only a tiny proportion of the embryos ended up “human”.
