“Why did you whites develop so much cargo [goods] and bring it to New Guinea, but we blacks had little cargo of our own? " [P. 14]. This question: Yali's question, is the focus of Jared Diamond's book Guns, Germs, and Steel. Diamond's claim is that the evolution of technology and general differences in the progress of society are due to factors such as geographic location, plants, and animals. “Technology may have developed more rapidly in regions with moderate connectivity [Europe], neither too high [China], nor too low [India]” [p. 416], says Diamond in the epilogue of his book hoping to provide further proof to his thesis. Diamond's vision of history is not the conventional one that a student reading the book might have every day, but it manages to lead the reader to consider, at the very least, his ideas. Yes says his book is “An ingenious attempt to explain racial differences in outcomes.” [Michael Levin]Diamond came across Yali while studying bird evolution in New Guinea as a biologist in 1972. Yali was a politician who, all the era in which met Diamond, he was attempting to prepare the people of New Guinea for self-government. Diamond is a professor of Geography and Physiology at the University of California and is best known for the aforementioned study of bird evolution and for his work in ecology and evolutionary biology. According to Michael Levin's review of Guns, Germs, and Steel, which originally appeared in the July 1998 issue of American Renaissance, Diamond's only visible prejudice is against hereditarians: people who attribute both genes and environmental factors to group differences .

The technical terms are well defined and the reader can understand what Diamond has to say even with minimal knowledge of the topic. Diamond provides numerous visual aids throughout his book, including numerous maps, graphs, tables, and even photographs of Aboriginal inhabitants of less developed countries. These photographs are a striking component in Diamond's work because the reader compares himself to the person in the photo and tries to come to the conclusion that, according to Diamond, mere chance separates one from the other in economic terms. Diamond's unconventional vision of history is well developed in his book and overall it is an exceptional work. Works Cited Diamond, Jared. Guns, germs and steel. Norton, WW & Company, Inc.
