    Includes a blistering critiue of the rare earth hypothesisTwo things have happened in recent years to persuade most scientists that life beyond earth is not just possible but likely Indeed some people including myself believe there is as the title of David Darling's book has it Life EverywhereWell not in the center of the sun or on the surface of a neutron star at least not life as we know itLife as we know it This is an important phrase that comes up again and again in discussions about astrobiology Life as we know it means life with a carbon base and liuid water David Darling considers silicone based life and even life forms so bizarre that we wouldn't recognize them if we saw them but basically he sticks with life as we know it in this very interesting answer to those who think that life in the universe is rareThe two things1 The discovery of extremophiles bacteria that live in sulfurous hot springs deep inside the earth and at the bottom of deep oceans Instead of deriving their energy from the sun they are able to use heat coming from within the earth to metabolize2 The discovery of scores of planets albeit not earth sized planets yet revolving around other starsWhat the first discovery means is that life doesn't have to exist or begin in conditions such as there are or have been on the surface of the earth but can thrive in places previous thought hostile to life That opens up a whole lot of the universe to life including parts of our solar system previously thought inimical to life such as in an ocean under the icy crust of Europa or beneath the inhospitable surface of Mars And the fact that planets are now clearly plentiful means that there are numerous places for life to developDarling who is an unusually lucid writer and a man who gets to the bottom of things begins with the nitty gritty problem of just how to define life If you haven't been introduced to this strangely knotty problem this book may open your eyes Do we consider reproduction metabolism growth etc in our definition? And which of these elements are essential and which are not? The postmodern definition now preferred by most people I have read is undergoes Darwinian evolution Is that adeuate? Is that the essence? Darling puts all the cards on the table and lets you decideNext Darling recapitulates ideas about how life began The main new idea is that life may be an inevitable conseuence of the nature of matter and energy It appears that matter is self organizing Darling reviews the ideas of how lifeless matter might replicate and how cells might develop from various molecules and water These leaky membranes could be the precursors of the first biological cells p 40He goes on to make the case for a universe with abundant life But along the way he presents a blistering critiue of Rare Earth Why Complex Life Is Uncommon in the Universe 2000 by Peter D Ward and Donald Brownlee in which it is argued that the circumstances that allow life are rare and that those circumstances as seen on earth are unlikely to be replicated anywhere else Darling not only utterly destroys their argument point by point but even shows that part of the reason that it was advanced was because they were under the influence of one Guillermo Gonzalez professor of astronomy at the University of Washington who is also a creationist with the usual supernatural agendaThis was bombshell to me But Darling shows that nearly every argument that Gonzalez makes is designed pun intended to discredit the idea that there is life anywhere but on earth On page 112 Darling refers to an article entitled Live Here or Nowhere co authored by Gonzalez for a publication called Connections published by Reasons to Believe Inc of Pasadena California whose mission is to communicate the uniuely factual basis for belief in the Bible The article concludes The fact that the sun's location is fine tuned to permit the possibility of life and even precisely fine tuned to keep the location fixed in that uniue spot where life is possible powerfully suggests divine designA couple pointsFirst Darling argues that life forms on other worlds however dissimilar their chemistry are likely to be familiar to us in the sense that if there is an atmosphere some will have wings and if there is an ocean some with have fins if there is a solid ground to walk upon some will walk and run and if there is light to see some with have eyes This idea of convergence is dictated by the laws of physics which reuires evolutionary adaptations to take forms that work efficiently within certain environments Of course if the life forms we eventually discover exist in great dust clouds their adaptations may be very dissimilar and surprising Even on solid ground here on earth some run and some hop some crawl and some slitherSecond since it is now known that bacteria spores can exist or less indefinitely some have been revitalized after hundreds of millions of years of dormancy see page 150 the once discredited idea of panspermia namely that life originated elsewhere in the universe and arrived here as spores has been rejuvenated Personally I've always liked this idea championed by Fred Hoyle and Chandra Wickramasinghe; however this book has convinced me that life could arrive from without or develop from within Either way or both seem likely to me Dennis Littrell author of “The World Is Not as We Think It Is”

    This is the first book of astrobiology I have read If you are looking for a general overview this is your book I just hope David Darling decides to write an updated book because many things have been discovered since 2001


  3. says:

    Fascinating and I just about understood the technical stuff


  4. says:

    David Darling does a nice job of introducing the science and practice of Astrobiology in his book Life Everywhere That's right aliens but not the aliens of the small imaginations seen in movies and weaker sci fi novels Life outside of earth is almost a certainty he contends and makes a pretty compelling case for it Darling brings together an overview of the history of life on Earth including the extreme forms of life that we have only recently discovered with discussion about what type of planets have the right ualities to harbor lifeand why Factor in the the vastness of the universe and the number of candidate planets that are out there and the prospect for ET microbes is tantalizing Describing scientific discoveries in several different disciplines this remains a very accessible book to a non scientist Unfortunately Darling lost his way for a chapter that distilled into a rant about Rare Earth a book that describes why only Earth could possibly have intelligent life If you have ever looked up into the night sky and wondered what if this book should give you cause to smile

    Some of this may be a little out of date at this point since the book was written in 2001 but I still thought it was a really good overview of astrobiology what scientists in the astrobiology community are looking for and where and why and how those findings will affect us here on Earth Although Darling definitely seems to be in the there's DEFINITELY life out there somewhere FOR SURE camp he comes across as open to the idea that further research and findings could prove that assumption false I don't really have an opinion on the matter myself but I think it's a really interesting thing to think about and read about Darling really conveys his excitement in the field well and while a couple other reviewers apparently didn't find this book very compelling I kind of did Anyway there are probably newer books that have up to date info but I really liked this one and am glad I paid a whole dollar for it at Half Price Books about three years ago ha

    Entertaining and mind expanding Darling presents his case ably in much the way a trial attorney would he starts with bold claims then presents supporting evidence in an authoritative way explaining its historical context and walking you through the scientific process the how do we know that generated that evidence Like a good lawyer he also pokes holes in the evidence for the opposing rare earth theory and raises uestions about the veracity and motives of its primary advocates Despite this obvious slant I never got the impression that Darling was hiding the ballThe biggest downside to Life Everywhere is that it was written back in 2001 a virtual lifetime ago for such a fast developing field of science Anyone know of a recent book bringing this story up to date?

    For all its enthusiasm this book does one thing astonishly well it refutes point by point the Rare Earth hypothesis which basically states that complex life as we relatively know it exists only on Earth I have yet to read Rare Earth don't really want to give them my money this book convinced me uite cocisely that its authors are wrong


  8. says:

    A very interesting introduction to astrobiology the study of life's origins and the search for its existence elsewhere in the universe It covers the history and current state of the field and it also discusses some of the controversy surrounding it


  9. says:

    Read this a ways back It's a counter argument to Rare Earth Why Complex Life Is Uncommon in the Universe but I don't recall it being very compelling


  10. says:

    A good if brief overview of astrobiology a bit dated now but a good answer to Rare Earth
