A London zoo Komodo dragon named Flora recently laid eight fertile eggs without the aid of a consort. According to the Chester Zoo, "[the] paternity test confirmed that all the genetic material in the eggs had come from Flora and that she was indeed both the mother and the father of the developing eggs." The clutch of eggs is expected to hatch around Christmas Day.
Parthenogenesis is a fact in some animal species. Besides some reptiles, earthworms are another example. Of course just because some species have this capacity doesn't mean that mammals including humans have it too. (This is despite the fact that a Japanese scientist was able to induce parthenogenesis in mice two years ago.)
So, Jesus and his mom were lizards?
