Recently, the latest research from Britain has transmitted an information: Since 10,000 years, the mankind has marked time in respect that brain capacity, body are high,etc. where it is, even fall back. Therefore, someone's pessimistic inference, the mankind evolving constantly in several million years has already stopped the step, reach limit. Interviewing department Professor Li FaJun of Zhongshan University's anthropology for this reporter, he thinks, the worry exist, misunderstand, human evolution stop never, until " the microcosmic is evolved " To understand the slight change that add or subtract on the human physique will be more objective. It plans Zhao to be clean to interview and write gentle ancient mankind fossil Li: British human Marta, house of theory of evolution, of Cambridge University draw the intersection of Hull and Dr., announce her latest research results in the Royal Society. She find want, talk about physical and thick and strong, than bad ancestor have a lot modern. Pass comparative analysis, the human fossils of 200,000 years before find in Ethiopia, than the fat person of the modern, and " more energetic " . In the human fossil from 120,000 to 100,000 which Israel found, bodily form is tall and big, muscular too. 10,000 years ago, ordinary people's average weight was among 79.83 kilogram to 85.28 kilogram, and the modern's average weight is among 69.85 kilogram to 79.83 kilogram. Drawing Hull will point out the media: "The mankind is still continuing evolving, but the evolution of the body size was stopped 10,000 years ago. " Why will this kind of situation take place? She thought, began 9000 years ago, adopted the life style hunted to transform into agricultural mode of production, have changed mankind's physical process. Though agriculture makes the food supply more sufficiently, the reduction of the food kind causes the mankind to lack vitamin and mineral element seriously, this has hindered the human body from growing. Except the physical respect, the human brain capacity seems to encounter the same question too. Draw Hull to point out, the volume of the brain of man 20,000 years ago is 1500 c.c.. The modern and male brain volume is 1350 c.c. on average, it is equivalent to a piece of tennis size volume to reduce. The decrease proportion of the brains of women is the same as this. The capacity limit of brain: May the major part become cumbersome instead? In the past, a lot of both inclined to think the human head of the future will be bigger and bigger. It seems now that this seems to be a kind of mistaken idea. The increasingly many brain scientist thinks, the development of the human brain has limit. Though in development in 2 million, the human brain volume has increased triple, but our brain capacity can not increase all the way. Echo with the research of drawing Hull, recently, Dutch neurology researcher Michel and Hoefman has put forward a reason why the brain can not be increasing all the time too - -That is a question of high energy consumption. Though the weight of the brain is only equivalent to 2% of the human weight, should consume 25% of human body's energy, this is well-above other organs. If the brain continues growing, will seize more energy and nutrient from other important organs, this will make human survival ability threatened. If the brain grows up all the way, the neuronal volume will thereupon increase, this will make the distance between the brain cell great, the axle which connects cells must become thicker and longer to dash for ward too. This will undoubtedly let the time that the electric pulse of cell transmits become longer, make the brain unable with the normal process information of speed. So major part might not right away clever, instead may let us getting obtuse. It seems like this that it might not mean we become more stupid that the volume is diminished, on the contrary, we will probably learn how to utilize our limited brain capacity resources to maximum degree. China's case: The intersection of Gui Lin and the intersection of rice steamer and leather the intersection of rock and the intersection of human brain and than modern the intersection of National People's Congress and until human the intersection of brain and change of capacity carry on research too nowadays some scholar of our country capacity. Anthropologist Wu beautiful to write articles, point out in the intersection of our country and the intersection of Gui Lin and south the Neolithic Age resident that suburb excavate while being outstanding - -The skin rock people of rice steamer, the male cranium capacity is 1459 ml on average, women are 1434 ml on average. The male cranium capacity of the modern residents in North China is 1406 ml on average, women are 1360 ml. From the Neolithic Age to now, the male cranium capacity has been reduced by 53 ml, women's cranium capacity has been reduced by 74 ml. The reducing of the cranium capacity, mean the shrinking of cephalic size, the human physique characteristic is still changing. In height, it is not in fact that the straight line of going the same way advances. Wu XiuJie points out, the height is closely related to nutritional status. The residents of the Neolithic Age of Chinese of 6000- 4000 years ago, the male height is 1.65 meters on average, women are 1.54 meters. The periods of Western Zhou Dynasty and Western Han Dynasty of 3000- 1800 years ago residents, the male height was 1.67 meters on average, women's height is 1.55 meters on average. Tang and Song Dynasty for Sui, the male height was 1.66 meters on average, women's height is average 1.56 meters. But by the sixties of the 19th century, the negative growth phenomenon has appeared in the Chinese height. The statistics show, in 1944, years old of Shanghai 7- 14 students of men and women's height, the students of the same age were shorter by 5.7- 7.3 centimetres on average than 1931- 1932. At present, our country's adult male height is 1.69 meters on average, women's height is 1.58 meters on average. Wu XiuJie points out, with the improvement of people's living standard, the height will also have increase of a certain degree, but will not present the trend of growth forever. According to the investigation, in higher family of the height, do not know generation and higher than a generation in height of its offspring, after becoming certain, the height of its offspring will present the downward trend. The expert dispels suspicion limit is said, dropped and said inaccurately The various microcosmic is evolved and never stopped so, can be from the anthropologist's research, the inference appears " Humanbeing evolution reaches limit " ," the mankind has already seen through the summit period for development " Or " over the past 10,000 years, the human physique is dropping constantly " ,etc. pessimistic conclusion? Professor Li FaJun of Zhongshan University human department thinks, instead of " humanbeing evolution reaches limit " ,Not so good as using " The human microcosmic is evolved " Objective fact that best reflects human development. The mankind is in results that the microcosmic evolves of any mutant emergence such as stature, brain capacity,etc.. According to such a visual field, do not just matter and " reach limit " The saying, there is no simple " evolve " Or " degradate " Saying. Li FaJun thinks, the view that the expert of Cambridge University puts forward accords with fact that the modern mankind evolves, but never mean the mankind has already seen through their summit period. "The mankind is the species of having naturally nature and social double attribute, culture has played a decisive role in anaphase and human evolution. Integration and segregation of culture, changes of the modes of production have all moulded the crowd of different culture of different periods. " He says. This is enabled Evolution human is one-way been type iron-plated,being being but full of by variety and changedded. Li FaJun points out, really stage is partial and little than early homo sapiens for the modern's brain capacity, but basically keep within smaller difference.
