I have read of popular science books, can be divided into three levels. The first level, author of facts, theories and ideas are not the results of their research, but by others, are the results of the scientific community recognized. The author of this knowledge to understand, digestion and absorption, using their own language, and the specific readers write articles and books. We read most popular scientific works are part of the hierarchy, such as the United States by Asimov, China Gao Shiqi and ye yonglie, popular science books on popular science writing masters, are attributable to this level, but this does not affect the value of these popular science books. The second level, the author of the material used, some facts and opinions is your own original, most is the fruit of others or their predecessors. As travel SEO Chinese geologists XU Jing Hua wrote the Geoscience revolution in colour and the curse came down from heaven: the riddle of the dinosaurs ". Xu Jing Hua participated in the 20th century in the 1960s and 1970s of Geoscience revolution, is also involved in the cause of the extinction of the dinosaurs. These two books in the author's own experience of participating in these events and contributions, but most of the content on one or the other scientists of experience and achievements. Belong to this level there is the Karl · sagen point Dim blue "and the" Cosmos ", Richard · niche of the origin of mankind". The third hierarchy, the works of the described is the author himself after years of research and exploration results. Works may also refer to someone else's achievement and related information, but that are used to serve their arguments. The author of the original thoughts and ideas may have been in the form of papers published in the open publication, but never to popular form presentations geared to the public. We have repeatedly mentioned · Rachel Carson's "Silent Spring" was a typical example. Our third issue of 2003 introduced by Jia red · diamond's guns, germs, and steel: the fates of human societies by "also works. This level of work include: Zhu kezhen "phenology", Xu Jing Hua of the Ming-Qing ancient seawall desert, Carl of the devil · sagen haunts the world ", etc. This issue describes the us why sick — the new science of Darwinian medicine "is such a work.
Modern medicine allows us for people suffering from a disease will have more and to understand, but why would a disease, but it is still difficult to answer. Now that our immune system to recognize and attack millions of different proteins, why people should get pneumonia? now that we can live to l00 years so why not live to 200-year-old? why we own like the eye, heart, brain, this ingenious perfect design masterpiece, has not arranged for preventing myopia, myocardial infarction and Alzheimer's disease measures of this kind? on the design of our body, it is beyond the normal level of accuracy and incredible oversights. As if the universe God exclusively those most brilliant designers on Sunday to go to a sloppy sloppy specialized will put rice burn disciples. However, this drop was obviously not make people happy, people also waiting for a more appropriate answer.
This answer is a nice R.M. University of Michigan (RandolphMNesse) and G.C Williams (GeorgeCWilllams) in 1994, they collaborated on "why are we sick-Darwinian medicine's new science" from the ascent of man's perspective, the answer to this question. It's simplified Chinese version purchased by Hunan Science Publishing House, was included in the Credit Union the first drive series, published in August 1998.
We tried to Darwinian medicine point of view to answer a few questions.
Why we prefer those on our bad food: oils, butter and sugar, but are not quite like vegetables and roughage?
In the course of human evolution, oils, butter and sugar are very scarce, malnutrition is the long era of priority issues. Only those who occasionally encountered oil, cream or sugar will be able to eat a man, to better adapt to the environment. Those who see these things but no appetite for people tend in childhood they died of malnutrition. Our ancestors have a hobby oil and sugar gene, now we have no lack of oil, butter and sugar, but our genes or command we: see these things look cool.
Why men and women's sexual response then is not easy, why not join the parties designed to reach orgasm, while obtaining maximum meeting of models?
Natural selection no matter whether you are happy, it just gene replication is successful. In the course of the evolution of mankind long, men competing for the spouse's struggle is very intense. Man and woman soon ejaculation climax contributed to relatively slow mating success. If a woman will soon reach orgasm, she may not successfully mate will be rejected; if a man to a long time to reach orgasm, insecurity increases, the other man's contention, the beast attacks, mosquito bites are dangerous.
Why was ill fever?
Fever is the defense mechanisms against infections, because when the temperature rises, some bacteria are killed. Used to control heating, sometimes it will make worse, even fatal. In the beginning of this century, Kalisz · Wagner · Coke Negro (Julius WagnerJauregg) of human fever value the most important evidence. He noted that some patients with syphilis in malaria after illness better, according to the high prevalence of syphilis in malaria areas, rare facts, as a form of treatment, it intends to make thousands of syphilis patients infected with malaria. In those days, syphilis is not natural to 1% remission rate, his fever therapy achieved remission rate of 30%. This significant achievement, won him the 1927 in Physiology or medicine Nobel Prize. At that time, the value of human cognition fever than now. However, if the human body to maintain body temperature 40 ° c there's nothing wrong with it, then just keep 40 ℃ to avoid infection, why wait until then to fever infection? however 40 ℃ temperature has a significant cost, energy consumption increased by 20 per cent, male
By temporarily infertile. High fever, may cause delirium, perhaps convulsion or even permanent organization, particularly in the central nervous system damage. Therefore, the heat is too high, or you want to use drugs to fever.We can try to discuss with Darwinian medicine on SARS virus spread.
At the peak of the SARS epidemic, someone wrote to speculate on the toxicity of SARS virus will each generation weak, because those drugs, makes people soon fell sick of SARS virus spread opportunities will be lost, only those toxicity is low, the infection can be free of viruses are more communication opportunities. Commentators also cites the case of Australia killing the rabbit. Australia to killing the flooding of the rabbit, from South America introduces myxoma virus, the early introduction of the virus killing 90% of the rabbit, but then the virus virulence gradually weakened its effects only 40%.
Can be proved that the SARS virus and does not display each generation weak trend, the virulence of SARS virus, its transmission capacity. In fact, the reason is simple, is not a rabbit. Rabbit in collapsed, the rabbit is no longer in contact with it, it's a virus in the body will not find a new host. People fell ill after some treatment, care, particularly severe patients, healthcare professionals will salvage in for a lot of contact with respiratory secretions, virus in this way to find new hosting. If the virus virulence of the weaker, less disease, respiratory secretions to spread less, plus patient will self isolation, the virus will not find a new host.
The SARS period, how Darwinian medicine of SARS, also attracted famous science fiction writer wangjin Kang (Henan oilfield oil machine factory senior engineer) and Tsinghua University Professor by earthquakes South and overseas scholars Fang zizhou heated debates between the interested readers can search from the Internet to the relevant information. Wangjin Kang long fiction the births and deaths balance law prophesied man in 2038, will suffer a super virus ravages.
