Japanese researchers announce a major accomplishment in this issue of Nature: the creation of the first transgenic primates able to pass on a foreign gene to their offspring (see pages 492, 515 and 523). Because the primates in question are marmoset monkeys that are distant from humans in an evolutionary sense, this experiment has little immediate bearing on the modification of human germ lines — a prospect that many people find unacceptable in any case. But the advance will lead to more sophisticated models for human disease, physiological development and neurogenetics. And in so doing, it will inevitably draw more attention from animal-rights activists.
