'A team of researchers affiliated with the University of Lincoln in the U.K. has found evidence suggesting that as the planet heats up due to global warming, the bearded dragon may become less intelligent. In their paper published in the journal Royal Society Open Science, the group describes exposing incubating bearded dragons to warmer than normal air temperatures and then testing their intelligence....To find out what impact rising temperatures might have on the bearded dragon, the researchers incubated 13 eggs, seven in a warmer than normal 30 degrees Celsius nest and six at the normal 27 degrees C. The researchers report that fewer of the lizards that incubated in the warmer pens were able to mimic the lizard on the video than those that had incubated at normal temperatures—and those that did succeed did so at a much slower pace. This, the researchers suggest, indicates that as the planet warms, animals across the globe will be impacted in some unexpected ways. For the bearded dragon, it could spell serious trouble if they become less intelligent, making them less able to adapt to change.'
