Six hundred million years ago, influenza was considered in animals as a reaction to infection: a high body temperature corresponds to the immune system. At that time, almost all animals were in the blood . To reach the maximum temperature for the floor , they need to be placed on a warm living board for a long time. Miss Logan, a Tupper man at the Smithsonian Institution for Tropical Studies (Patriarchal Institute for Triple Studies) in Panama, said the first presence of warm-blooded animals was probably due to disease. At first glance , this is much easier for cold-blooded or "ectothermic" animals. Because they cannot control body temperature, they emit 30 times less energy than hot or " endothermic " equivalent animals. Therefore, while animals and birds inject calories regularly to maintain a high body temperature, reptiles and aquatic organisms can find a warm place in the environment if they need comfort. But if ectothermia is so great, why are animals and bir...
