I love popular science books, but it's a quiet sort of love: it's not often a book like this gets me really excited - but Meet the Neighbours (sorry, I know it's Neighbors, but it grates) does just that. Once upon a time there was quite a market in books speculating about life on Mars, but of late most Martian titles have focused on getting to and colonising Mars (though often avoiding the 'c' word). Steven Benner drags us back to see the evidence for life having existed there, and does so with a vengeance. (Almost literally - he really lays into those who are dismissive of what evidence there is.) Do we have proof? Well, no - but proofs are for mathematicians. As Benner says 'science does not deal in proof... Rather, it relies on a 'preponderance of evidence' standard to shift the burden of proof.' Benner points out the weird reality that since the Viking landers, which arrived in the 1970s, there hasn't been a mission looking for organic sig...
Remarkably for those who came across it in the early days, this classic of popular science writing is now 50 years old - and like many of us who reach a certain age it has become somewhat overweight: a reasonable sized paperback has morphed into a 500-page monster. Even so, we have to recognise the importance of the book, despite its message not being as clear as it once was. One major change is that Dawkins, with his God Delusion hat on, was once the hero of the provisional wing of the progressive movement, where now he has been pushed aside for daring to suggest that there are only two sexes. The other change, of course, is that the science has moved on and some of the genetics certainties of Dawkins' day have reached the scientific stage of 'it's more complicated than we thought.' In a couple of chapters that weren't in the original book and about 120 pages of discursive end notes and an epilogue, Dawkins attempts to clarify some scientific developments and to ...
