Written in 1981, this account of the origin of life by Nobel laureate Francis Crick has aged a bit. Some big-picture Sagan-esque cosmic notions here. The main idea he presents is directed panspermia, and I expected him to articulate and sell the idea a lot better than he did. He even admitted that it seemed unlikely and he didn't even mention the serious problem of cosmic radiation. Essentially the bigger problem is that it just shifts the question elsewhere. A bit like the ancestor simulation theory of reality. However I did appreciate Crick's recognition of this as one of the truly difficult problems in science, and his articulation of the details of these difficulties.
