Komodo dragons can reproduce through self-fertilization
"The tests on the embryos and on Flora, her sister and other dragons confirmed that Komodo dragons can reproduce through self-fertilization." …
"Flora, a pregnant Komodo dragon living in a British zoo, she 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.” … this was the first time it has been shown in Komodo dragons — the world’s largest lizards.
"The scientists, reporting the discovery in the science journal Nature, said it could help them understand how reptiles colonize new areas. A female dragon could, for instance, swim to another island and establish a new colony on her own.
“‘The genetics of self-fertilization in lizards means that all her hatchlings would have to be male. These would grow up to mate with their own mother and therefore, within one generation, there would potentially be a population able to reproduce normally on the new island,’ Buley added.”
