Page 9. " Most books that set out to recount world history concentrate on histories of literate Eurasion North African societies. "

This bookmark shows how unlike other books concerning human past, this book will see it in light of other civilizations and people. 

*Eurasia is referred to the idea of the combined bodies of Europe and Asia.

Page 9. " First, increasing numbers of people today are, quite understandably, interested in other societies besides those of western Eurasia. After all, those 'other' societies encompass most of the world's population ... "

This bookmark shows how Diamond believes it to be a disadvantage that even people who hold dominance in the world - both economically and politically - are still not mentioned enough in history. He thinks its these small societies inside Eurasia that deserve to be noticed.

Page 10. " Second, even for people specifically interested in the shaping of the modern world, a history limited to developments since the emergence of writing cannot provide deep understanding. "

This is another problem Diamond explores that exists when we do not seek to undersatnd history as an "onion." Through this bookmark he shows why he has "peeled" deeper and deeper into the soul of our history. He has questioned and investigated many such issues in this book. 

Page 10. " "Third, a history focused on western Eurasian societies completely bypasses the obvious big question. Why were those societies the ones that became disproportionately powerful and innovative?" "

This bookmark further emphasizes the need for Diamond to bring light on history that has been considered "not important." He shows how we cannot understand how societies came to be until we have a full understanding of the background of all groups of people around the globe; he explains how we have to understand a stance from all sides of the stories. 

Page 13. " ... some parts of the world developed literate industrial societies with metal tools, other parts developed only non-literate farming farming societies, and still others retained societies of hunter-gatherers with stone tools. "

In this bookmark Diamond tries to explain the background of how different nations and continents across the globe have built up at different rates; he does this to further "peel" off his onion to explain why one kind of people grew faster than others. He will explore geograohical and other factors too. 

Page 13. " In July 1972 I was walking along a beach on the tropical island of New Guinea ... "

This is a bookmark mentioning the start of a small anecdote that Diamond uncovers to explain how he formed such questions of the human race. He goes on to demonstrate how he does not have a racial approach to his understanding. Furthermore, he discusses how Yali (a local politician in New Guinea) questioned him to why Americans and Europeans came to New Guinea? He mentions how this book is a response to his question because he was not able to answer at that time. 

Page 14. " The conversation remained friendly, even though the tension between the two societies that Yali and I represented was familiar to both of us. "

This bookmark seeks to explain how at the time the people of New Guinea were seeking indendence; that is the tension between the groups mentioned above.

Page 14. " Many of the white colonialists openly despised New Guineans as 'primitive.' "

This bookmark shows the background information between the colonialists and the citizens of the country. This is one of the major reasons why the New Guineans were fighting for independence. 

Page 15. " For instance, why weren't Native Americans, Africans, and Aboriginal Australians the ones who decimated, subjugated, or exterminated Europeans and Asians? "

This book mark shows how Jared Diamond questions history and how it could have been different. It is through these questions and quotes that he catches the reader's attention.

Page 16. " The stone technology of the Tasmanians, when first European explorers in A.D. 1642, was simpler than that prevalent in parts of Upper Paleolithic Europe tens of thousands of years earlier. "

Page 25. " Naturally, the notion that environmental geography and biogeography influenced societal development is an old idea "

This quote is trying to prove that environmental and biogeography is very relevant even in today's age.
