    Piece o' shiteThis is supposed to be about science but one of the co authors is an ordained New Age minister with no science background at all although she's very interested in paranormal phenomena WTF? I gave up on the book shortly after I came upon the section devoted to the importance of volcanoes to ScientologistsIn addition the book was either not copyedited at all or copyedited by the worst copy editor on the planet Tons of typos and affecteffect used incorrectly every single time I ran across it

    A very interesting topic — but muddled by too many deviations including a scenario of a possible supereruption in our days

    Less than scientificA lot of interesting information a lot of conjectureThere were some facts I was unaware of but also a lot of psycho babble How the effects of the Toba eruption would effect the psychology of survivors and be transmitted to people today by 'cellular memory' No proof to back that up It's ok to present theories in a nonfiction book but too many theories in one book tend to make it all seem wildly improbableToba did erupt and there does seem to be proof of a subseuent evolutionary bottleneck but there was too muchfluff for lack of a better word to make this book into something I could take as fact I like to use nonfiction as reference books because I am interested in everything This book does not meet my criteriaResults if you want to know all about supervolcanoes read a different book

    My rationale errors in data reported for volumes used linear measurements instead rather consistently over a large number of pagesA rarity for me to publicly say I did not finish a book but this is one instance in which I feel obligated to do so There are many clear instances where factual data are reported incorrectly Specifically volumes are cited using distance names rather than the appropriate cubic ones I suspect that the difference of having or not having a superscripted 3 is of no conseuence as the intended audience is general readership rather than scientifically or mathematically tuned readershipIf I have time to read a book rather write and edit them I will try to come back and finish this work but right now I am too busy to be distracted by loose scholarship that these consistent errors point to

    Lots of theories and psychobabble and badly formatted It was a meh book kind of boring and with fonts that were distracting as well as things like a graph paper design around pictures that made the captions harder to read Each chapter had a cheap fractured text effect that was just annoyingMight be worth reading once if you're bored

    Pretty scary to think of these huge calderas right here in North America The Toba one devestated the early human population and almost made us go extinct but we were resiliant enough to live through it Pretty amazing that all humans at today are descended from the 3 5000 individuals to survive the Toba supervolcano Wonder what would happen to us today should the Yellowstone or Long Valley Calderas erupt? They are technically overdue

    Excellent book on a human population bottleneck 70000 years agoThis book explores in detail the history of the Toba supervolcano eruption about 74000 years ago and it's effect on human evolution in the aftermath of the volcanic winter that followed the catastrophic eruption Very thought provoking book Highly recommended

  8. Ann Ann says:

    It started off interesting enough but went completely off the rails when it started getting into genetic trauma

  9. Tom Tom says:

    The geologic information on volcano's was good I skipped the last chapter

  10. Judith Judith says:

    A well written book that doesnt reuire any specialist knowledge as the author explains the science well
