Question

Quizplus · Accepted Answer

Lizards, being ectothermic, rely heavily on external temperatures to regulate their body heat. Rapid global cooling would severely affect their ability to maintain necessary body functions, making them more susceptible to extinction compared to other taxa with more adaptable or resistant life history stages.
