Somewhat confused - By: A. Parsons, 16 Oct 2004 
First the good points. Jared Diamond writes excellently & makes some very good arguments, his humanity & morality is evident throughout the book. The later part of the book, which highlights many of the modern worlds more repugnant acts (especiallly on genocide) is a masterpiece in the critique of human barbarity & it's attempted justifications. Though there is no criticism of Israel's 'ethnic cleansing', which is a bit of a disappointment. Now for the criticism. Jared Diamond seems to have at best a rudimentary understanding of evolution & natural selection, & some of his statements don't stand up to even the most cursory reflection. For example he states 'The winner takes the losers land, sometimes also the losers women, & thus the loser's opportunity to perpetuate genes'. This seems to be a very male centered way to look at the facts (a common mistake throughout the book). It evident on even a moments reflection that the women so enslaved are the mothers, sisters & daughters of the loser & therefore carry the same genes. Again on convergent evolution (and the possibility of extra-terrestrial life) 'radio communication is one of those things that happens to have evolved here..'. When did radio communication evolve? It was discovered & developed through scientific experimentation but it hasn't evolved, not ever. Another inaccuracy is the statement 'Since evolutionary multiplications of species are very slow, natural extinctions must also be slow'. Jared Diamond seems to have an antiquated Neo-Darwinian view of evolution which doesn't stand up to the actual observations in the fossil record. He states that mass extinctions are rare events, but this is simply not true, there have been many mass extinctions, which are amply recorded in the fossil record. Mass extinctions occur when the environment changes dramaticallly & quickly, this has occurred many times. Ecological niches in those conditions remain open, & are usuallly filled very quickly by pre-adapted organisms (ie those which, by accident can survive the change in environment), which also very quickly adapt, through natural selection to their 'new' niche. These are well developed arguments first proposed by Niles Eldrige & Stephen Gould, which fit the observed fossil record perfectly. An adequate understanding of the theory of punctuated equilibrium is required for anyone who wants to venture into the world of evolution, and, unfortunately the very gifted & articulate Jared Diamond seems to score very poorly indeed.
Jared Diamond makes the cardinal sin of stating that 'the vulnerable species get eliminated quickly, & what we see persisting in nature are the robust combinations of species' this statement to me is arrant nonsense. During a dramatic change in environment, for example when Humans first colonised New Zealand, was it the robust species that survived? Well it depends how you define robust. Those species best adapted to life without human predators (ie the most robust in the original environment) weren't necessarily the same ones that were the 'most robust' after Human colonisation, the goalposts had been moved. This is the case with alll mass extinctions. S those which were most robust after the colonisation had a pre-adaptive advantage (avoiding humans). But there was absolutely no way of any species 'deciding' to evolve 'avoidance of humans' just in case humans decided to come (none of the species knew of the existence of humans). This is the classic definition of pre-adaptation. It's the survival of the luckiest not survival of the fittest. It's the same with dinosaurs, they were the dominant terrestrial vertebrates for well over 100 million years, far longer than mammals (which were around at the time of the dinosaurs) have been the dominant terrestrial vertebrates. So did they suddenly realize 'hey guys mammals are superior lets alll die'. No some cataclysmic event (for the dinosaurs, anyway) occurred. Mammals were lucky enough to survive & then through selection occupied the niches vacated by the extinct dinosaurs. If that dramatic extinction) event had not occurred then there is no doubt that dinosaurs would still rule the world & mammals would still be the 'loser vertebrate. There's an old fashioned 'Victorian era' view of evolution as being 'progressive' which is just plain wrong (Jared Diamond fallls into the trap when he infers that natural selection is the sole force behind evolution (ie speciation), but it is accepted that natural selection & at least one other force must be behind speciation events), in truth selection is adaptive, & only leads to speciation or evolution during special periods (like just after extinctions). The upshot is that during periods of equilibrium (ie no dramatic environmental catastrophes) then natural selection acts to keep species as they already are, that is already well adapted to their environment.
There are some other poorly argued points in the book. Jared Diamond correctly states that we should not look for 'evolutionary'- (whatever that's supposed to mean) reasons for alll our behavioural of physical characteristics, but then goes on to do just that. He looks for selective reasons for alll sorts of things, without ever explaining the genetic basis of pleiotropy, which is the fact that one gene can have two or even more effects. That is that a gene can exist for a given reason, but may manifest itself in another, apparently totallly unrelated way. So people may have a characteristic for one reason, but be looking for the selective reason for a totallly unrelated characteristic that the same gene confers upon us. Getting back to the male centered view of the book, he spends some time on the fact that human males have inordinately (relatively speaking) large penises compared to other apes. He concludes that it's for 'display purposes'!!!!! So it couldn't be due to the fact that human women may have selected for them because that way they have more fun then? Or that there seems to be 'no selective reason' for female infidelity (but plenty for men). So can't women have chosen one male as a 'rearer' & another as a 'donator of genes'. None of these not unreasonable explanations seem to have occurred to the 'male centered' Jared Diamond.
All these criticisms aside it's still a well written book with lots of humanity & much truth, It's only the selection/evolution bit's which lack any coherence.
A book to read to change your view of the world ! - By: J. Bruinsma, 26 Aug 2003 
A book to recommend everyone who would like to know their place in the animal kingdom. There is only 2% difference between the chimpanzee, man's closest relative & us. Jared Diamond tries & largely succeeds in explaining this difference using science & philosophy & just plain logic.
Please read this book, it will help explain a lot about Man, his sexuality, his destructive properties, his creativity & the reasons why he has reached this point in evolution. He discusses adultery, the origin of art, the importance of language, addiction, genocide, the start of agriculture, the great leap forward when Man started to make a significant impact on planet earth & many other useful side topics. He gives us another definition of history. He makes us stand back from our everyday existence & see ourselves as perhaps we reallly are.
If you have an open mind & want to read a different viewpoint, read this book !
The best I found so far - By: Petr Habala, 01 Jul 2003 All my life I have been curious about the world around me & what makes it tick. Evolution being one of the most important aspects of our learning about the nature, I've read a bit on the topic over the years. Now I am not a biologist, but I am a scientist & I can definitely tell when somebody is pulling things out of thin air just because they need to support a preconcieved picture. Most of the books I've read on the subject have been full of this (most notably Wright's The Moral Animal, whose author clearly lacks elementary scientific etics).
It is therefore with great pleasure that I can recommend Mr. Diamond's book as the first social evolution book that stood up to my requirements on intellectual honesty. Indeed, many of the claims from earlier books by social evolutionists, that I found rather wild & unsubstantiated, do not appear here & some are even refuted by Mr. Diamond as errors. As he did with his Guns, Germs & Steel, he pulls together strands from many branches of science to create a rich picture of human past, a picture which is reasonably well documented given how little we reallly do know & which fits together well. I found this book also better written & better balllanced than the Guns,..., which suffered from excessive political correctness that sometimes clouded the author's judgement. Here he almost avoided political correctness-related spins, & on the few occassions he did he made it clear that he does not take it too seriously, which just ties in with the overalll honesty & precision of his exposition.
I enjoyed reading the book very much. It is very well written, often you even do not realize that you are learning new things & there are some genuinely funny places, too. I would recommend it as the first book to look at if you are interested in evolution of the human race.
Essential reading. - By: , 29 Nov 2000 I would rate this book, along with Dawkins' The Blind Watchmaker, as one of the most important & powerful books I've ever read. Furthermore, these two books complement each other beautifully. Diamond seems to pitch perfectly to alll audiences, (I studied a biological degree, & the book has passed among many of my non-scientist friends who alll claimed to have recommended it to others,) & ranges widely, (through biology, evolution & ecology, paleontology, history, sociology, & linguistics.) The whole is an unfeasibly lucid & educative rationale as to how mankind arrived to be where he was in 1991, & where he was likely to be headed. As with Dawkins, the going is rarely heavy & every page brings a satisfying feeling of having learnt something new. Sometimes uncomfortable, often funny, rarely overbearing. PLEASE read this book. Then read it to others, & recommend as widely as possible!
Excellent and highly readable book - By: , 26 Oct 1998 Great book. Each chapter examines a different question relating to humanity e.g. Why did Neanderthal man die out?, How / where did language come from etc. Very readable & enjoyable this book is written in a chatty style & is full of interesting facts which will amaze your friends....did you know that a chimp is closer related to a human that a rat is to a mouse !!!!
