为什么人的体貌、身体情况,甚至内脏的大小、血细胞的数量千差万别,体温却都不超过37℃?在生命演化的最初阶段,生物都不能维持自身体温的恒定。为了适应生存环境的变化,保证大脑等精细结构随时能正常运转,很多动物慢慢建立起了体温平衡系统,成为恒温动物。把温度上限“设定”在37℃,同样是进化的选择。科学 Why human body, body condition, and even the size of the internal organs, the number of blood cells vary widely, the body temperature does not exceed 37 ℃? In the early stages of life evolution, the creatures can not maintain their body temperature constant. In order to adapt to changes in the living environment, to ensure that the delicate structure of the brain can be functioning at any time, many animals slowly established a body temperature balance system, a thermostat animal. The upper limit of the temperature “set” at 37 ℃, the same evolutionary choice. science
