Virgin births discovered in wild snakes

http://www.bbc.co.uk/nature/19555550


A virgin female and her son

A form of virgin birth has been found in wild vertebrates for the first time.

Researchers in the US caught pregnant females from two snake species and genetically analysed the litters.

That proved the North American pit vipers reproduced without a male, a phenomenon called facultative parthenogenesis that has previously been found only in captive species.

They've known about parthenogenesis in lizards, for example, for many years.

Link to 1971 paper on the subject.

If lizards are not vertebrates, I give up and crawl back into my time capsule. I never thought I would see the old become new again within my own lifetime.

Thus NOT the first time in vertebrae:

It was thought to be extremely rare for a normally sexual species to reproduce asexually.

First identified in domestic chickens, such "virgin births" have been reported in recent years in a few snake, shark, lizard and bird species.
