The bible is no longer the only place where youโ€™ll read testimonies about a virgin birth.

In a new study published in the Proceedings of the National Academy of Sciences on [March 7], researchers at Shanghai Jiao Tong University report the results of a new experiment where they were able to make a female mouse give birth to a baby mouse that grew from an unfertilized eggโ€”something that has never before been accomplished in mammals.ย

In the wild, this form of reproduction is a common sight among invertebrates like worms and honey bees; and sometimes among vertebrates like sharks, California condors, and anacondas. But parthoneogenesis isnโ€™t natural for mammals, due to whatโ€™s called genomic imprinting.ย

โ€œI think there are people who will look at this and say, โ€˜Oh, is this going to replace reproduction? Get rid of men?โ€™ No, itโ€™s not,โ€ [molecular biologist Marisa] Bartolomei, who also was not involved in the study, told The Daily Beast.

But what the new study may do is help scientists study a family of congenital diseases caused by genomic imprinting, like Prader-Willi syndrome (where children are born with a constant sense of hunger and developmental issues), or Beckwith-Wiedemann syndrome (a disorder that is characterized by a childhood risk for cancer).
