When the heat is on, lizards become smarter - potentially giving them a competitive edge as the world warms. Previous research has shown that scincid lizards (Bassiana duperreyi) grow larger if their eggs are incubated at higher temperatures. Joshua Amiel and colleagues at the University of Sydney, Australia, wanted to see if bigger lizards also make better learners, so they incubated nine eggs in cold conditions - 8.5 to 23.5 ℃ -and 12 in warm conditions -14.5 to 29.5 ℃.
