One of the best books I read this year and not one I had been planning to read I skimmed a few reviews which were interesting but did not leave me thinking that I needed to read the full book But then I started a sample on a whim and was swept away by the carefully observed descriptions of octopuses and to a lesser degree cuttlefish and the use of that as a springboard to discuss evolutionary biology and the philosophy of the mindOctopuses are a type of mollusk and like all invertebrates branched off from the stream of animals that led to humans enormously long ago and well before the evolution of central nervous systems eyes or much else of any sophistication But now octopuses have large collections of neurons rivaling mammals but they are evolved largely independently of ours And they have important differences for example most of their neurons are distributed in their arms rather than collected together in their brain This leads Peter Godfrey Smith to speculate about what this says about intelligence and whether we should think of body parts as having their own autonomous intelligences in the form of reflexes or even higher order thought in octopuses Some of the interesting speculations are about how humans benefited from the feedback loop between our sensing of our own actions eg we can hear ourselves talk while octopuses and cuttlefish can make impressive color displays but are themselves colorblind so they do not see their own displays nor do they use them to communicate with othersTowards the end the book turns poignant as Godfrey Smith relates how this highly curious and interactive animal the closest thing to an alien we have on earth only lives for about two years much less than anything else its size and intellectual sophistication This leads into both the evolutionary biology of aging and its link to reproduction and ultimately an homage to the ocean and conservation that is less original than much of the book but powerful for how much he learned about the human mind from swimming on the bottom of the ocean

Despite what might be gleaned from your Star Treks and Dr Whos the evolution of intelligent life is – as far as I can get my head round it – infinitesimally rare and unlikely The emergence of cells the development of eukaryotes the first multicellular organisms the start of sexual reproduction and finally some kind of freak evolutionary drive towards increased intelligence – all these things happened once only and didn't have to It's presumably happened somewhere else in the universe which is a sizeable place but I wouldn't be surprised to learn that we're the only example in the 200 billion solar systems of this galaxyPeople interested in such things have spent a lot of time trying to put concrete numbers to the odds of these things happening That last step – the development of intelligence – seems among the most unlikely but one of the implications of this utterly fascinating book is that perhaps it isn't so uniue after all Enter – by jet propulsion – the octopusInvertebrates are not generally known for their brainpower But octopuses and to a degree all cephalopods are an exception In terms of sheer neurons they are well up there with many of the mammals – they have neural connections than cats for example As Godfrey Smith puts it they are ‘an island of mental complexity in the sea of invertebrate animals’That does not mean that the way they think is comparable to us though or to your pet Persian Although a few of an octopus's neurons are gathered into a walnut sized ‘CPU’ of sorts most of them are dispersed throughout their body each of their eight arms can in a very real sense ‘think’ and act independentlyGodfrey Smith though often wearing a marine biologist hat is a philosopher by training and he spends a lot of time here addressing the uestion of what it might feel like to be an octopus without a centralised ‘self’ in the way that we understand it I thought I would find these sections irritatingly speculative which is my reaction to most philosophers if I'm honest but in fact they were so grounded in scientific data and just so interesting that I was than happy to go along for the rideUltimately though the differences are perhaps less significant than the similarities The most recent common ancestor of humans and octopuses lived upwards of five hundred million years ago and was probably some kind of very simple worm like thing without any neural network to speak of That means that natural selection has completely independently developed complex ‘intelligence’ of some kind twice‘Cephalopods and smart vertebrates are independent experiments in the evolution of the mind’ Godfrey Smith summarises The implications are genuinely awe inspiring And looking at an octopus is in all likelihood as close to meeting an alien intelligence as we'll ever get

Octopodes or the floppy floppy spider of the sea source ZeFrank are pretty freaking amazing Godfrey Smith agrees which is how this book came about As he notes on page 9 If we can make contact with cephalopods as sentient beings it is not because of shared historybut because evolution built minds twice over This is probably the closest we will come to meeting an intelligent alienUnfortunately he tried to marry it with one of his professional passions the philosophy of consciousness and that's where this falls uite short The beginning chapters have a uick explanation of the evolutionary tree and then start tracing the origin of life and neurons through a brief look at the fossil record This is supposed to impress upon us how different we are from octopodes but if you didn't already know that I don't know how you would have selected this book So that was weird to me Each chapter has a teaser opener of a real life octopus situation then goes into theoryJulie has a very solid thorough analysis on what went wrong and why and I strongly suggest it if you are wondering whether or not this is for you I am occasionally in the mood for philosophy but grow uickly tired of discussions of perception of pain consciousness and possible perception of self To me consciousness and pain uickly boils down to experience I see something witness and try to escape potential painpain; therefore it experiences it enough that it deserves consideration does it not Does it actually matter if it conceives of itself as an individual Whatever That isn't the point the point is that these conversations uickly grow tiresome to me because it seems the ultimate in superiority complexes all the ironic coming from a race that can't manage to not to destroy its own environment And now I'm off track again Anyways here's what's interesting octopodes can recognize people They also tend to suirt water at things they don't like There's numerous anecdotes of them specifically targeting a person they don't like with a jet of water or all new visitors to the lab the Ediacaran period had peaceful creatures that were basically like bathmats that crawled around munching and seemed to not have sophisticated sense organs or protective armament I have no idea what this has to do with octopodes but it's a super fun visual image I picture a herd of bathmats grazing on my lawn cuttlefish are also cool and may actually be color blind although they have the astonishing ability to blend with their environment there's a secret octopus garden on the east coast of Australia Or in a Beatle's song Which is awesomeThere's some neat colorplate photos in here as well as some black and white drawings and illustrations in an attempt to help the reader with visuals ie evolutionary tree the fossil record The end chapter where he talks about studies at Octopolis are genuinely interesting and I would have read much about what's coming out of there Actually now that I'm listening to it again watching ZeFrank is a uicker and fun and references many of the same octopus facts that were in this book
