Yesterday I posted a a story about one of the classic themes of biological SF – regenerative medicine. However, there is one area of SF that sees quite a different aspect of biology as more important. Feminist SF has for some time been very keen on the idea of Parthenogenesis, the ability to have babies by asexual reproduction, without the need for men.
Can it be done? Well sure. Amoeba do it all the time. For that matter is has been observed in lizards, sharks and chickens. There are (according to Wikipedia) a few cases of it having been done on small mammals. But now a German-Israeli team of biologists think that they have found a genetic trigger that turns on the ability in any species that has that gene. Thus far they have only done it in plants, but that’s obviously just a start.
