This system may have evolved together with high heart rates to support their endothermic state (warm-bloodedness) and is seemingly lacking in ectothermic vertebrates from which first mammals then birds independently evolved. Here, we studied the conduction system in crocodiles (<i>Alligator mississippiensis</i>), the only ectothermic vertebrates with a full ventricular se ...[more]
