同学们,当你为一道数学题做不出来而发愁的时候,你的大脑就开始活动了,经过大脑的一番努力,你终于解出了难题。此时,你有没有想过,把历史追朔到300万年以前,我们的祖先——古代类人猿在直立行走以后,不断加深了对外界事物的认识,经过一代一代地进化,人脑逐渐完善了。应当认识到,脑部发展的过程,也就是人类脱离动物界的过程。现代科学为我们提供了这样一条数据:大猩猩的平均脑量只有415毫升,北京人的平均脑量约1088毫升。现代人的平均脑量约1450毫升。1450与415的差异,——多么惊人的数据呀!显而易见,这两个数字的差异,就是人与动物的差异。更重要的还有:人脑的内部构造也比大猩猩的脑复杂和完善得
Students, when you are worried about being unable to do a math problem, your brain starts to move. After some brain work, you finally solve the problem. At this point, have you ever wondered how to trace the history to 3000000 years ago, our ancestors - ancient apes walked upright, continue to deepen the understanding of the outside world things, after a generation of evolution, the human brain gradually improved It’s It should be recognized that the process of brain development, that is, the process by which human beings are separated from the animal world. Modern science provides us with such a data: the average brain volume of gorillas is only 415 ml, Beijingers average brain volume of about 1088 ml. The average brain of modern people is about 1450 ml. The difference between the 1450 and the 415, how amazing the data! Obviously, the difference between these two numbers is the difference between human and animal. More importantly, the internal structure of the human brain is also more complicated and better than the gorilla’s brain
