SUMMARY ✓ Seven Clues to the Origin of Life A Scientific Detective Story Canto This book addresses the uestion of how life may have arisen on earth in the spirit of an intriguing detective story It relies on the methods of Sherlock Holmes in particular his principle that one should use the most paradoxical features of a case to crack it This approach to the essential biological problems is not merely light hearted but a. A general generic understanding of the origin of life is that organic chemicals came together by chance in just the right way so that replication occurred Then random variation and natural selection took it from there and favored the better replicators Cairns Smith doubts this speculative account of life s origins He argues that the essential stuff of life DNR RNA and proteins are much too complex and must have been preceded by organized entities that did not need nucleotides links in the DNA chain but could have evolved to produce them In his view non organic and very microscopic crystals in clay are the key Crystals grow and replicate This self assembly process is based on the perpetual motion of atoms and molecules that combine with other atoms and molecules to bond in particular ways The perpetual motion of the molecules allows them to try out many possible arrangements and they can thus arrive at some particular arrangement that has the greatest possible cohesion Such an arrangement once found will of course tend to persist Mistakes are made during replication and these defects or irregularities contain information in this case size and shape that are then repeated as the crystal structure grows as long as the defect does not compromise stability of the structure itself This replication process built upon mutations errors is subject to natural selection that favors those that allow for continuous self assembly and weeding out those that don t contribute to suchSomehow from all of this Cairns Smith concludes that The very first organisms were inorganic crystalline in nature not organic molecular as organisms are now and that The origin of life on Earth is a branch of mineralogy The switch from life to non life is described as a transition from primary organisms unevolved and so not yet alive to begin with to secondary organisms through a gradual replacement of genes made of one material by genes made of an altogether different material that is to say through a genetic takeover At this point I lost the trail the transition point between inorganic non life and organic life which of course is the central thesis of this book The author also describes the origins of life as an inner impulse that unfolds organically but I wonder how the active importation of energy from the outside fits into his argument and why that might not be central to the distinction between non life and life These are not criticisms This book though hard to follow provides another perspective on life s origins and it is good to know that his argument is out there
