~READ PDF ☪ Why Is Sex Fun? The Evolution of Human Sexuality ♼ Why Are Humans One Of The Few Species To Have Sex In Private Why Are Human Females The Only Mammals To Go Through Menopause Why Is The Human Penis So Unnecessarily Large There Is No Knowledgeable Authority Than The Award Winning Author Of The Third Chimpanzee To Answer These Intriguing Questions Here Is A Delightfully Entertaining And Enlightening Look At The Unique Sex Lives Of Humans Writing as a Jared Diamond fan, I am sorry to report that Why is Sex Fun is a letdown His central hypothesis is that sex is applied selfish genetics, without so naming it.He argues that the act of procreation in a given specie is predictable given knowns such as is the relative energy investment in the developing egg and what is the certainty of the embryo being the genetic product of either parent The reader is assumed to have a background in evolution theory and this book applies that information to possible arguments By extension the argument is that the basics of normal human sexuality are a practical application of that same theory The title question is answered, if not directly or in so many words The book is out of date, not much of a standalone book and less interesting than the title promises The book may have been intended for inclusion in a larger undergraduate reading list I cannot recommend it.Despite what other reviewers say the title question is answered Just not in so many words The answer isor less the point of Chapter 4, subtitled The Evolution of Recreational Sex.That this book is dated is not entirely Prof Diamond s fault In terms of Evolutionary Science the 20 years since its original publication is a long time I am not sure it is represents a contribution great enough as to valuable as to justify a rewrite.Prof Diamond asks several questions built around relatively unique aspects of the human sex act Hidden ovulation preference for private performance copulation during times and ages when pregnancy is unlikely or impossible Some of these things are rare in most animals or at least among our fellow primates Answering each of the questions is the theme of each chapter The answer is almost always a matter of applying the rule that adult members of a breeding pair assume roles based on the individual mates energy investment in the young, certainty that the young possess the genetic make of the parent and that no later sex act or relationship endangers that embryo.Given the brevity of the book there is little space for competing theories or even much discussion of evolutionary theory Nor is there much in the way of supporting research In an undergraduate course other reading material may provide for these absences but as a stand alone book it is not up to the standard of other books by the same author.Prof Diamond s explanations can be interesting He will usually include a survey of species that have or may have had similar practices The discussion, with diagrams that help to show that the fossil records can provide clues about which extinct species may have practiced some of these behaviors is worth a read The problem is that he simply states that this kind of analysis is possible and never makes much effort to prove this possibility Prof Diamond in effect invokes his authority as a sufficient proof This may work in an undergraduate course, and especially if there are other texts in use in that class It is not sufficient to make this a standalone read for the general public. This was a mostly tedious book to get through The only thing that stopped it from being 1 star was a few interesting facts and details that bumped the rating. Why is sex fun Who the eff cares It just ISif you re doing it right, that is Ha I thought the book had a lot of promise, but it failed to deliver on many, many levels Diamond s lack of footnotes really irked me and I was left questioning a lot of his research I mean sure, learning about the number of hermaphroditic fashion models really boosted my self esteem, but hello Source please I don t have time to go digging around through his entire bibliography looking for relevance Ultimately, I learned a lot about animals and very little about humans C est la vie. It seems that Jared Diamond got better and better with every book he wrote With practice he got exceptionally good at making comparisons between species, cultures, etc He also developed a better focus on the subject with every book.However this book was written before any of that While it is easy to read, it contains little info and has strange examples It also alludes too often to the author s sex life in a Look at me I m a successfully married man with a sex lifehoray way Diamond tries to explain various reasons for various sexual habits cycles, goes on rants about the analogous examples in the animal world and attempts to draw occasionally weak parallels to humans Jared also seems side with certain virginal nerd men I know in that most men are scumbags and women deserve better I disagree because women have the option to pick whoever they deserve and I will not accept blanket insults against my sex.I still somewhat recommend this book because of the random bits of information in it For example polygamous Mormon men especially priests are the peak of male evolution in that that on average the have the most children 25 Plus it s an amusing book to read in public places.The most frustrating aspect of this book is that Diamond forgets to answer the most important question of all the one on the cover What the hell Now upon finishing the book every reader has to go out, experiment and answer the question for themselves. I ll admit I cam into this expecting sociology with a little bit of biology, but instead I got the reverse There are a lot of comparisons drawn between humans and other species, as an evolutionary explanation for our sexual evolution is attempted I think not including any observations on how lgbtqia people may fit into the picture is an oversight, but overall this was an informative book. in case if you frown upon the title, I would like to highlight that the author is a biologist, he is neither a saint nor a sinner biology as a science has a sort of philosophical completeness that the physics, the most fundamental of all science doesn t possess biology can answer both how and why questions molecular biology and or genetics do answer the question of how , for example, they can tell you the step by step process of how a living being dies, but they will definitely fail to answer why we die at all the why questions in biology are addressed by the theory of evolution if you stuck with any riddle in biology, just ask Mr Darwin, he has the final say.physics has quantum mechanics, the theory of relativity and they can satisfactorily answer the question like, how does the subatomic particle interact with each other or how a galaxy is formed but unlike biology, physics has no theory that can answer the why questions, why a particle interact in the way it does or why gravity exists that for the galaxy etc put it in another way, there is no theory of evolution in physics but we can imagine, once such theory of why emerges in physics, it will face the same resentment as the evolution the first word in the title implies, this book is on why and not on how why the human has so distinctive sexual biology than other primates or mammalian species so far, I ve got the opportunity to read five books by Mr Diamond they broadly fall under two categories about human as a species, this book and the The Third Chimpanzee belongs to this group the second category is about human society, Guns Germs and Steel , Collapse and World Until Yesterday goes here.some of the topic in The Third Chimpanzee has been discussed in great detail in this book here two concepts those I couldn t resist sharing as I never thought them in the way they were presented beyond any doubt, the brain and the thumb are the key adaptations those changed the fate of human species Mr Diamond argued that biologically female menopause is as revolutionary as the human brain and thumb unlike males, females of human species got their reproductive system shutdown by the age of fifty, while they live several decades afterward, apparently, without any reproductive advantage why is so the human birth canal was not evolved to deliver an enormous human fetus or twin, as a woman grows older her mortality due to childbirth increases significantly a human child requires a long time of nursing and caring before becoming independent, and in old days society couldn t sue a father for refusing his childbearing responsibility hence aselderly women died during childbirth, their infants used to follow the same fate of their deceased mother, and genes not promoting the menopause were slowly removed from the gene pool menopause helped the single mothers to live longer and take care of their babies in early hunter gather and forager society the lesson is that the world we see today wouldn t be possible without single mothers.the second interesting point was about old people before the invention of writing, people used to memorize enormous knowledge about their environment, plants, animals, etc as they get older, when they could no longer hunt or bring food to their tribes family instead of becoming obsolete, they turned into a library old people were the living libraries in the ancient society, they were valued and honored by their people it is the invention of writing that took away the job from old people as the librarian and turned them into a social burden.if you think carefully, biologically humans are good for nothing not only in childbirth, the humans were not a good hunter, so they opt for foraging, they were not good at foraging either, so they adopted agriculture as history tells us, the humans were not good even in agriculture, soon they formed civilization and raged war against each other apparently, they were so bad in the war that they stop their conquest and focused on science technology and guess what, even after two hundred years of advanced science and technology humans were found to be worse enough not to figure out why question in physics isn t it weird Shame on Mr Diamond for luring me in with this clever title What this book really is is a scholarly tome for the serious anthropology student It is interesting that, when it comes to sex, humans do a lot of things very differently than even our closest animal cousins The book looks at why men have nipples, why humans continue to have sex even during pregnancy when there s no chance of additional procreation, and how various species evolved with obvious or hidden signs of ovulation complete with charts going back to the missing link The bottom line is, almost all animals have sex solely for passing on their genes One of the most interesting story is about a species of male bird who sets up one mate in a nest and makes sure the hatchlings are on their way and then goes and sets up another nest with another mate, flying back and forth between both families Meanwhile, other males may be lying in wait to spend time with a female while her mate is away But other than that, the book can get pretty dry There s a long discussion of the possible benefits of hidden ovulation Does it keep the man around because he never knows for sure when the female is fertile I m not sure Diamond ever answered this question I think I may have fallen asleep Sex is fun Why Is Sex Fun is not. While sort of dating somebody that was very, very ill suited for meso much that I was absolutely certain that we had no future, he would never be introduced to my family, et cetera et cetera, I really started being interested in the subject of sex Attraction The difference between women and men s approaches to it, the difference between pure physical attraction and what people call chemistry Pure, simple sexual attraction and then the kind of attraction that develops While ultimately I didn t place much stock in the relationship, the undercurrent of sexual tension that buzzed between us was undeniable I would find myself gazing at him in total awe, body abuzz And then I d wonder why Sure, I d found him gorgeous at first sight but it was being in each others company that had done it, now my feelings opinions had multiplied and it seemed like there had never been anybody MORE gorgeous the first time he reached for my hand I was buzzin And I couldn t make sense of it, it was totally out of my hands Whether or not I wished to be attracted to him this way, I was Of course I am a human being and with my evolved brain am able to grasp the weight of my choices and their consequences so I am not a slave to my body, but it was my body s reaction that piqued my interest Like why this person I d been around beautiful men plenty, men technicallybeautiful than he, why so enad with this one And so I ve picked up a few books on sex, this one being the 2nd I ve read, Bonk by Mary Roach the 1st So, the fact that I had been looking to learn about something that was kind of specific, this book was a little bit of a let down But only in the sense that there wasn t enough info on what I wanted to know Sure, there was a brief mentioning of pheromones and how they are potentially responsible for the chemistry thing I guess I wanted them to be a littlespecific, like explain what s happening. draw me a diagram of the route these pheromones take thru me, the synapses and nerves, the brain waves and activity Maybe I m just crazy for wanting an explanation for my attractions There was a lot of random educational info, stuff I am less inclined to care about like the sex lives of animals and the anomalies and rarities that exist in them An entire one out of the 6 chapters in the book is devoted to animal sex actually, including gems like listing other animals that enjoy sex, others that partake in same sex sex, others that have sex in private like humans instead of out in the open There was a chapter on menopause which according to this book is something that happens only to human females A chapter on breast feeding and the supposed non evolution of male lactation, A chapter on gender roles in sex, yadda yadda It s all interesting enough to read about, but that s because SEX in general is interesting to read about I still prefer this book to Mary Roach s Bonk because it reported facts in an interesting and witty way without laying on the lame jokes so heavily and breaking the fourth wall constantly the way Roach does Also Mary Roach isn t a Dr or professor on the subject, or any subject, which causes me to mistrust a littleJared Diamond who also wrote Guns, Germs, and Steel is both a Dr and Professor of human sexuality That lends him a littlecredibility in my eyes, and it shows in his writing which isn t amateurish the way Roach s is.SO For anyone looking for a quick and interesting read, sort of random facts about sex human sexuality this shouldn t disappoint It s short, and mostly interesting and written in a manner that an average person can enjoy it You don t have to be a dr or a scientist to understand it, is what I mean Tho, it won t explain to you why you just can t seem to get enough of your new gf bf, or why the sex with your plain jane neighbor is soo muchamazing than with your smoking hot ex Or why you aren t attracted to Mr Perfect with the body like a greek god, and yet you are borderline obsessive about the cute cater waiter from last night s dinner I have twobooks on the subject but something tells me that searching for an explanation of my attraction to a man is like searching for the meaning in lifedestined to be fruitless forever but at least reading about sex is never dull This book was fascinating and so engaging and easy to read for a book based in biology In it, Jared Diamond brings up numerous facts about human sexuality that we all take for granted Humans have sex for fun whether or not they are fertile, at any time of the month or year Human females experience a distinct decline and then abrupt stop in fertility around middle age Women usually have little idea of when they might be ovulating unless they are using some form of modern technology to tell them These simple facts of life which most of us accept as normal, are actually very, very odd in the rest of the animal kingdom Diamond discusses how these traits and behaviors evolved and how they make us uniquely human.I loved this book Diamond is like a great professor of any subject he makes you excited to go out and talk about his subject to your friends and to learnon your own time I never thought I would like a non fiction book about biology so much.
