Researchers at the University of Sidney in Australia have concluded that rising global temperatures have increased the brain functions of lizards. Quicker response times in simple learning tests have been recorded when these tiny lizards are exposed to higher temperatures. This has lead to some concluding that as the world continues to warm, so will the cognitive behaviors of our reptilian neighbors. Another interesting fact is that cooler temperatures lead to more male lizards, while warmer temperatures lead to more female lizards. This should cut down the population rate of these super-smart lizards and prevent them from taking over.
