[Think] of an experience from your childhood. Something you remember clearly, something you can see, feel, maybe even smell, as if you were really there. After all, you really were there at the time, weren't you? How else would you remember it? But here is the bombshell: you weren't there. Not a single atom that is in your body today was there when that event took place . . . Matter flows from place to place and momentarily comes together to be you. Whatever you are, therefore, you are not the stuff of which you are made. If that doesn't make the hair stand up on the back of your neck, read it again until it does, because it is important. ↗

I recently asked more than seventy eminent researchers if they would have done I their work differently if they had thought Darwin's theory was wrong. The responses were all the same: no. I also examined the outstanding biodiscoveries of the past century: the discovery of the double helix; the characterization of the ribosome: the mapping of genomes; research on medications and drug reactions: improvements in food production and sanitation; the development of new surgeries; and others. I even queried biologists working in areas where one would expect the Darwinian paradigm to have most benefited research, such as the emergence of resistance to antibiotics and pesticides. Here, as elsewhere, I found that Darwin's theory had provided no discernible guidance, but was brought in, after the breakthroughs, as an interesting narrative gloss. ↗

The male frog, in mating season," said Crake, "makes as much noise as it can. The females are attracted to the male frog with the biggest, deepest voice because it suggests a more powerful frog, one with superior genes. Small male frogs - it's been documented - discover that if they position themselves in empty drainpipes, the pipe acts as a voice amplifier, and the small frog appears much larger than it really is." "So?" "So that's what art is, for the artist," said Crake. "An empty drainpipe. An amplifier. A stab at getting laid." "Your analogy falls down when it comes to female artists," said Jimmy. "They're not in it to get laid. They'd gain no biological advantage from amplifying themselves, since potential mates would be deterred rather than attracted by this sort of amplification. Men aren't frogs, they don't want women who are ten times bigger than them." "Female artists are biologically confused," said Crake. ↗
Prediction in a complex world is a chancy business. Every decision that a survival machine takes is a gamble, and it is the business of genes to program brains in advance so that on average they take decisions that pay off. The currency used in the casino of evolution is survival, strictly gene survival, but for many purposes individual survival is a reasonable approximation. ↗
Personally, I've always found the study of life incredibly boring – I much prefer to just live it. I do enjoy speculating on life, though. But to go and ruin that speculation by checking it against facts, it's terribly disappointing. I'm afraid it would turn me into a cynic. ↗

Random mutations much more easily debilitate genes than improve them, and that this is true even of the helpful mutations. Let me emphasize, our experience with malaria’s effects on humans (arguably our most highly studied genetic system) shows that most helpful mutations degrade genes. What’s more, as a group the mutations are incoherent, meaning that they are not adding up to some new system. They are just small changes - mostly degradative - in pre-existing, unrelated genes. The take-home lesson is that this is certainly not the kind of process we would expect to build the astonishingly elegant machinery of the cell. If random mutation plus selective pressure substantially trashes the human genome, why should we think that it would be a constructive force in the long term? There is no reason to think so. ↗
