In 1995, an academic book titled "Human Sperm Competition: Coitus, Masturbation, and Infidelity (Lun)" set off an uproar and controversy in the media in the United States and the world. Baker and his colleague Bayliss became famous overnight.It was Baker who rewrote it based on this book. The reason why this book caused an uproar is their amazing discovery: human sexual behavior is the result of long-term biological evolution, and the dominant human sexual evolution is the sperm war, that is, the sperm war is the basic element of all human sexual behavior.Although human beings born through sperm wars only account for about 20% of the total birth rate, and although the consciousness of both sexes thinks that the chances of sperm wars are so small, the essence of evolution is that their bodies are blindly Get ready—for the sperm wars to come.The authors also support their findings with laboratory findings and studies of similar performance in other animals, making their case quite convincing.

The author of this book specially set up 29 scenes to emphasize the need of human sperm war.These scenes cover every aspect of human sexuality.This is the originality of the author, and it is also the place where this book has received great attention and welcome from readers.In this regard, the author who only appears as a "recorder, classifier and commentator" hopes that readers will not use any emotional factors and rational judgments, and should only focus on these behaviors themselves. It's also impossible to do it all, and he admits to getting emotional more than once in scenes of his own design.The stories of these scenes are very strong, as the author said, "There is a story hidden behind the birth of every life, even your birth is no exception."

Since these scenes describe human sexual behavior very straightforwardly, almost as a "naked display", I think that the readers of this book should be limited, and it should be adults. However, as a new scientific discovery and new scientific theory, their point of view obviously still needs to be further enriched and improved: First, the sperm war for the purpose of reproduction cannot cover all aspects of human sexual behavior.According to the usual understanding, human sexual behavior (or intercourse) has at least three basic purposes: one is to pursue sensual pleasure; the other is to express love; the third is to reproduce offspring (see American J? Theory and Practice of Ethics).However, it is not comprehensive to attribute the rich and colorful sexual behaviors of human beings to the purpose of procreation; secondly, the author deliberately avoids the psychological and social cultural aspects of human sexual behaviors in order to examine human sexuality from a biological point of view. This is just a hypothetical situation for the sake of experimental observation.In real life, it is completely impossible to avoid value judgments made by people's psychological activities, emotional expressions, and social and cultural factors.Therefore, human sexual behavior under these hypothetical conditions is only one-sided, abstract and formalized. These things can only reduce the colorful human sexual behavior to an animal instinctive behavior.This is not enough for us to correctly understand the nature of man.

To sum up, I think this book is scientific and innovative, and the author's academic attitude is rigorous and serious, which is worth introducing and publishing. Xu Tianmin, Chairman of the Chinese Society of Sexuality October 2003 Expert Guided Reading (Part 2) I am really afraid to write a recommendation for this book, because the love scenes depicted in the book will definitely be criticized by some moralists as extremely harmful works.However, I also feel that I must muster up the courage to recommend this excellent puzzle book, which is so thoroughly researched on sex and so wonderfully written, to all those who take love seriously.

You have to understand the various strategies of male and female love from the perspective of biological evolution.In order for the individual's own genes to be successfully passed on to the second generation, the male's sperm (animals and humans are very similar) must have all kinds of surprising strategies to overcome all difficulties in order to win the female's hard-fought mature eggs , Defeat the opponent, to win a tragic sperm battle.I remember that 10 years ago, I was still working as a consultant at the Salk Institute for Biological Studies in San Diego, USA, and every Thursday afternoon was the time for our academic seminars.The topic of one post was: "Sperm Jihad: The Price of Sustainable Development!" The speaker was a well-known animal scientist, so many people came here attracted by the name, but most of them thought it was a witty topic. It's just for fun. I didn't expect that after a speech, everyone would know that there will be such a well-defined plank road in the womb of a female animal.For example, in the womb of a female chimpanzee without interbreeding habits, if there are sperms from different male chimpanzees, the two sperms will start a life-and-death fight, and there is a strategic division of labor, definitely not random arbitrary chaos prick.First, there will be a group of sperm whose task is to find alien sperm, and then fight and die together, called "Kamikaze" type sperm; then there will be another type of sperm, their task is to surround It is called BlockerSperm to block the heterogeneous sperm and surround the eggs tightly, preventing the heterogeneous sperm from passing through; the sperm in the best state emerges finally.The wonderful performances of these three types of sperm are really breathtaking!

But this sperm war is very superficial, and it is a face-to-face war of valiant and high-spirited spirit.The mate selection of female animals is a very clever and subtle operation.Women in many countries and from all cultures have contraceptive strategies.They would stuff certain leaves or fruit (or crocodile droppings!) into their vaginas to prevent pregnancy.And as described in the book, humans are not the first animals to invent chemical contraception. For example, female chimpanzees know how to chew certain leaves containing contraceptive chemicals at the right time to weed out unwanted sperm.If one cannot look at the performance of these "sex plays" from an evolutionary point of view, it is impossible to infer these wonderful reasons anyway.

In fact, female animals not only have a choice of fertilization objects, but also have certain restraint on the quality of fertility.Women during pregnancy often have a lot of ideas about the living environment of the baby to be born. They will move the furniture and furnishings around the house. When they feel unsatisfactory, they will also cry and feel depressed.They "instinctively" want to provide the best raising family environment for the next generation.The maternal motive is strong, both in humans and in animals in general.This kind of precautionary nesting behavior is very obvious in pregnant female birds.I once observed on a female white-crowned sparrow a female bird who worked hard to build three nests at night, which made me feel admiration for the greatness of maternal love.But think about it carefully, isn't this "selfish gene" at work?

If you can read this book from such a perspective of biological evolution, then you will feel that scientists' understanding of "reproduction" has indeed made great progress.This book is rich in content and unconventional. It hides the scientific knowledge about "sex" in 37 scenes of intercourse between men and women. I am not very used to the narratives in these scenes, because they are too western and too avant-garde .But put aside our incomprehension of western social culture, and focus on the level of scientific analysis, I found that this is really an eye-opening sex book.Also, the translation of this book is also very commendable, it is rare to read such a good translation.So I can only tell young friends nowadays: instead of spending money to watch bad movies, it is better to save money and buy a good book!

Here!This is it! Zeng Zhilang, academician of Taiwan's "Academia Sinica" and president of Yangming University Expert Guided Reading (Part 3) Since Darwin, natural selection and sexual selection have emphasized that animals tend to produce more and better offspring to continue the life of the species.We all know that individuals are mortal, but their germ cells or genes never die.All animals find ways or use their reproductive strategies so that their genes can be passed on forever to the next generation.So human sexual behavior is no exception, so that one's genes can be passed on to the next generation forever, or even passed on forever.The ultimate goal of all organisms is to enable their genes to survive, which is the result of tens of millions of years of evolutionary events.We use a phrase from Dawkins to describe it as a so-called "survival machine" to produce some genetic well-being that can last forever.

In order for an animal to carry forward its genes, it must be transmitted to the next generation through the process of "reproduction". Therefore, general evolutionary biologists emphasize and study feasible theories to assist individuals to reproduce successfully so that they can pass on to the next generation. It means to enhance its reproductive success rate (individual fitness value), so that its genes can be passed on and flourish.If the reproductive success rate is zero (the fitness value of the individual is zero), not only the individual will perish, but his genes will also perish.Therefore, each animal will have its unique reproductive strategy, so that its genes can be passed on to the next generation, or even passed on forever.

The author of this book describes from the point of view of genetics that human sexual activity is innate and inherited from ancestors. Just like other animals, their sexual behavior is very similar to that of human beings. Although this book uses human sexual behavior as the starting point to describe human reproductive strategies, the text does not contain a pedantic language. It can be said to be an easy-to-understand "popular science" novel, and it is very readable. It is a supplementary reference book for "sex education".
