Summary: Great overview of mammalian evolution
Review: This is a marvelous book for anyone interested in the course and
mechanics of mammal evolution and extinction. Tudge presents complex
theories intelligibly and heated controversies fairly. The reader need
not go along with his drastic social prescriptions in the final
chapter in order to appreciate his clear, exhaustive grasp of the
scientific subjects. One aspect in particular to be grateful for is
Tudge's overview of prehistoric South American mammals--the best such
in a popular science book since George Gaylord Simpson's death. The
book is docked a star for reasons beyond the author's control
(according to private correspondence with him)--no pictures of all the
wonderful beasties he describes! Boo-hiss to the publisher for such
cheapness.

Summary: interesting and carefully considered
Review: A wordy expose on how humans have impacted their environment for their time on earth with valuable insights on why things went the way they did. For example, Tudge covers the extinction of large mammals in North America by humans (it was a mathematical certainty, he says), the rise of agriculture which lead to our rise in population, and how our agriculture may just be our own doing in. Tudge explores current theories and then comes to his own conclusions which all seem plausible by the book's end. If you want to avoid searching the bookshelves for human ecological and biological histories, this book may sum up what you need to know.

Summary: An extraordinary, awesome, stimulating reading exercise!
Review: Colin Tudge is a concerned man. Constructing one of the most complete pictures of human evolution's course, he draws on geology, meteorology and biology in setting a framework. Tudge then explains how and to what extent Homo sapiens emerged from Africa to override the planet. That's a hefty task, particularly in less than four hundred pages. Especially given that he allocates ten per cent of those pages to assessing the future. Tudge's concern about human impact on the environment is the theme of his other works, but this one rests on a solid foundation of evolutionary biology. Tudge Dances Through Time in explaining the movements of continents and the impact of that mobility on lifeforms. Movement, an adventure life normally avoids, is forced by changes in environment. In seeking to stay with the familiar, life migrates in response to change. With environments continually shifting, life must adapt to survive. Humans have broken the pattern, invading the globe's many environments. We are the most adaptable species to emerge. The price of our adaptation has been the extinction of many species, particularly large prey animals and birds. On every continent large birds and mammals ceased leaving fossil remains shortly after the appearance of Home Sapiens on the scene. The timing is too consistent to be purely coincidental and the ensuing patterns of human behaviour show we remain essentially ignorant of our impact on Nature's balance. We shouldn't be surprised at his finding. Today we face decimated cod and salmon populations. Whales remain under assualt in the face of a 'moratorium' on their killing. The number of populations extermined due to our occupation of their habitat is beyond counting. Tudge's concern is valid and it must be hoped infectious given the background he provides. Those who grizzle about Tudge being "wordy" are misleading you. He's precise with words, although this book must set some kind of record for superlatives. New readers take note: Tudge has one disturbing habit. He will introduce a term [edentates, for example] and never find an alternative thereafter. When you encounter a term you don't know, make certain you understand it before continuing. This habit detracts neither from the worth, clarity of presentation nor value of this fine book. At first read the lack of a Bibliography seemed a flaw. Second thoughts showed that a suggested reading list would likely have doubled the size of the book. Build the bibliography yourself as you encounter authors and titles in the text. If the citations are unfamiliar to you, spend the energy. Tudge is too good an introduction to the topic to ignore.

Summary: A Good book, but...
Review: First, I really did like the book. It was on the whole well-written, and had a number of good ideas which were new to me. (Such as the concept of an "ecomorph", and his thesis about the origins of farming.) I was quite frustrated with the book on a number of counts though, and feel the need to vent. I just finished reading the hardcover edition, and feel it would have been greatly improved by better editing. There are a number of places in the text where it repeats, almost word-for-word, earlier passages. One gets the impression that the chapters were written separately, and not adequately "flowed" together. There were also a number of very obvious errors, such as two places in Chapter 8 where totally erroneous Fahrenheit equivalents were given for Celsius temperatures ("...more than 6 degrees C (43 degrees F),..."). While minor, these shake one's confidence in the book's accuracy! I was also quite disappointed that there were no footnotes and references. I just finished looking for them on-line, in the hope that the information would be available somehow. No luck. Maybe this could be done in the future, if the publishers desired to omit them from the printed version. I did like the book, and certainly do not regret spending the time to read it. But compared with a classic such as _Guns, Germs and Steel_ I found it wanting in terms of editing and references.

Summary: outstanding
Review: I just taught this book in a Philosophy and the Environment course, and I would jope that my students enjoyed it as much as I did. An excellent overview of all aspects of the earth sciences (geological disasters, ice ages, asteroid collisions, atmospheric chemistry, plant and animal life). The concept of the "ecomorph" was a fascinating one that I had never heard of before but will not soon forget following Tudge's lucid presentation. He also makes some eye-opening remarks about the impact of agriculture and the human species in general on many now-extinct or soon-to-be-extinct animal species. I actually found the final chapter slightly anticlimactic: not bad, but not nearly as riveting as some of the earlier ones. Even so, this book has turned me into a nature enthusiast for the first time since early childhood, and will surely be only of the first of hundreds of books I will read on the topics he discusses. In that sense, Tudge has had a huge impact on my life, and if you read this book attentively it is likely that he can do the same for you.

Summary: no references, alas
Review: I liked part of this book, especially some of the new ideas he brings up, but I have been unable to find any references to the ones I have tried to pursue further (such as weather control projects in progress in Israel). This leads me to wonder if some of the parts that contain original and stimulating ideas are actually simply untrue or misrepresentations. For example, he seemed to deliberately misrepresent (or misunderstand) the parallel evolution theory of human origins, so that he could re-present it in more convincing terms as his own original idea. All in all, the fact checking seems weak, (eg, a change of 6 degrees centigrade is equivalent to a change of 36 degress farenheight !?!? Obviously someone with a pocket calculator mindlessly punched numbers into the temperature formula to get that one) and the lack of references for some of his assertions leaves me wondering about their accuracy. This is a real shame, because a few of his ideas are ones I had not encountered before (for example, exposed rock faces having a major effect on the amount of carbon dioxide in the atmosphere, and hence having a major impact on global climate), but I reluctantly have to say that I'm not sure he is a reliable source.

Summary: no references, alas
Review: I really wanted to love this book. I had just finished Jared Diamond's _Guns, Germs, and Steel_ (a must read BTW), and picked this one up because I thought it would discuss the period of time before Diamond's book really got into. I didn't really get what I expected. If you read the book discription on the back cover, it gives the impression that the book would cover human and hominoid development from about 5 million years ago until recent history i.e. 10,000 years ago. There are some good parts in this book. I particularly liked how he gave an overview on how evolution works. He explained things well and I was able to follow pretty easily despite being a complete novice regarding the specifics on the theory. I also liked the section on human evolution and how he explained the possible causes and effects of the spread of Homo sapiens. His discussion on the overkill hypothesis was top notch. However, this book is not without its flaws. One major flaw for me was the fact that the main topic only takes up about half of the book. There is a long chapter on mammal development, and at times he just simply lists creatures haphazardly. It would've been nice to have a chart to identify the possible ancestors of animals that are alive today. A glossary would have been nice as well. I got tired of trying to find the first time he mentioned poikilothermic animals just to name an example. Yeah I know, I could've written down the definition, but is it too much to ask an author to do what most other authors do? A bibliography would've been wonderful too. There didn't seem to be that many references in the text, and I would've liked to see others sources for further reading. The final problem for me was the fact that the book wasn't really about what the description on the back cover says. For example, the first chapter is a detailed description on how the climate and atmosphere works on earth with a warning about excess CFC's and the depleting ozone. Next he describes the different types of mammals and proceeds to seemingly describe every one that lived in the past and present. There are so many names and descriptions that they kind of all blend together. There is a chart, but it isn't detailed enough for you to really follow the author. Finally, the last chapter is a plea for humanity to be careful and not kill off any more animal species. Now before people start assuming that I am anti-conservationist let me clarify. I love animals as much [messed] up. However, reading about those topics is not why I bought this book. I bought it to read about the devlopment of Homo sapiens in the past, not a "save the ozone and don't kill the animals" plea, which really took up about a third of the book. To summarize: If you're looking for a strict account on human evolution then I wouldn't buy this book. There is too many other topics that the author focuses on and really doesn't give that subject the just amount of pages in this book.

Summary: 30,000+ Years of Momentum
Review: This book covers the history of mammals since the fall of the dinosaurs, but focuses mostly on humans and our impact on the world - especially for the last 30,000 to 60,000 years. Starting with a short overview history of Earth and the movements of the continents, Mr. Tudge works methodically to his ultimate goal for this great book... What has been our impact on this planet, how much momentum have we gathered and how far will we go before we reign ourselves back into the natural world. Did humans cause the Pleistocine Overkill? Were our ancestors 30,000 years ago merely the most voracious hunters, or were we proto game managers? Are the large scale extinctions occurring in our own time our fault? Mr. Tudge uses solid science, archeology, paleontology, etc. to create a framework of investigation and then isn't affraid to interject some of his own conclusions and provocative thoughts along the way. This book makes a create compliment to Jarred Diamond's Guns, Germs & Steel giving us a very deep picture of who we are and where we are going.
