Virgin birth expected for Komodo dragon in UK zoo

LONDON (Reuters) - Flora, a pregnant Komodo dragon living in a British zoo, is expecting eight babies in what scientists said on Wednesday could be a Christmas virgin birth.

Flora has never mated, or even mixed, with a male dragon, and fertilized all the eggs herself, a process culminating in parthenogenesis, or virgin birth. Other lizards do this, but scientists only recently found that Komodo dragons do too.

"Nobody in their wildest dreams expected this. But you have a female dragon on her own. She produces a clutch of eggs and those eggs turn out to be fertile. It is nature finding a way," Kevin Buley of Chester Zoo in England said in an interview.

He said the incubating eggs could hatch around Christmas.

Parthenogenesis has occurred in other lizard species, but Buley and his team said this was the first time it has been shown in Komodo dragons -- the world's largest lizards.

Scientists at Liverpool University in northern England discovered Flora had had no male help after doing genetic tests on three eggs that collapsed after being put in an incubator.

The tests on the embryos and on Flora, her sister and other dragons confirmed that Komodo dragons can reproduce through self-fertilization.

"Those genetic tests confirmed absolutely that Flora was both the mother and the father of the embryos. It completely blew us away because it (parthenogenesis) has never been seen in such a large species," Buley explained.
