What do the films Godzilla and Jurassic Park have in common? OK apart from the depiction of large bipedal reptilians. What I'm trying to get at is they both use parthenogenesis as a plot device. Godzilla lays all those eggs in Madison Square Gardens, and the dinosaurs have frog-filler DNA which enables them to start breeding and thus allowing in the element of chaos that Jeff Goldbloom's character witters on about.
So far so sci-fi. Reality however has a knack of catching up with our imagination. A Komodo dragon in Chester Zoo has just laid eight self-fertilised eggs! The biologists' conjecture is that this is an evolutionary strategy to enable a single female to colonise an island by producing a batch of male offspring who can mate with her, and kick start the population.
I'd always felt that this was one of the weaker plot devices of both films. Parthogenesis? In large lizards? Yeah right. And now it seems that biology has proved them right. I bet it's morphic resonance really.
