人类的活动无不受到了地理环境的影响,这就是俗话讲的“一方水土养一方人”。一、地理环境影响人类的容貌肤色是色素积淀的多少决定的。低纬度光照强烈,黑色素积淀得多,因而是黑色人种;高纬度地区的白种人因为阳光微弱,黑色素积淀得很少,故为白色人种;中温带介于中间,故肤色为黄色。白种人的眼睛是蓝灰色的,其原因是白色人种的源地是阳光高度角很低的北欧地区。大家注意过老鼠的眼睛没有,蓝灰色对吧?也就是说蓝灰色的眼睛适应光线的微弱,大家不要忘了人也是动物。如果 Human activities are all affected by the geographical environment, which is the saying goes “water and soil on the one side to support people.” First, the geographical environment affect the appearance of human color is determined by the amount of pigment accumulation. Low latitude light, melanin accumulation is much, so is black race; high latitudes Caucasian because of weak sunlight, melanin accumulation is very small, so white race; middle temperature, so the skin color is yellow. Caucasians’ eyes are blue-gray in color because the white race is originated in the Nordic region where the sun’s altitude is low. We note that there is no mouse eyes, blue-gray right? That blue-gray eyes to adapt to the weak light, we do not forget that people are also animals. in case
