Climate-change is turning males into females

Dragon lizards, that is…

The researchers, who have long studied Australia’s bearded dragon lizards, have been able to show that a reptile’s sex determination process can switch rapidly from one determined by chromosomes to one determined by temperature.

Lead author Dr Clare Holleley, a postdoctoral research fellow at the University of Canberra’s Institute for Applied Ecology, explained: “We had previously been able to demonstrate in the lab that when exposed to extreme temperatures, genetically male dragons turned into females.”

“Now we have shown that these sex reversed individuals are fertile and that this is a natural occurring phenomenon.”…

University of Canberra Distinguished Professor Arthur Georges, senior author of the paper…highlighted the importance that these discoveries have in the broader context of sex determination evolution.

“The mechanisms that determine sex have a profound impact on the evolution and persistence of all sexually reproducing species,” Professor Georges said.

“The more we learn about them, the better-equipped we’ll be to predict evolutionary responses to climate change and the impact this can have on biodiversity globally.”

Imagine how quickly our Congressional do-nothings would get off their rusty-dustys if it was determined that just a fraction of the semi-literate, obedient, party lever voters in the hotter climes of this nation were being tweaked from male to female!

We’d have a nationwide policy of carbon-reduction before you could say Koch Brother seven times in a row.
