That is, the molecular interactions in the biosphere held a similar role to the flurry of ideas in a reasoning mind. Being able to develop ideas quickly and without whole generations having to suffer and die is a great improvement to the process, but it is an improvement natural selection (not we) made. Biological evolution is now largely inconsequential compared to the evolution of technology and ideas. But the trends in technology and ideas are still evolutionary. Reason may be able to make longer strides than was possible with mutation of DNA molecules, but the products of reason are still very much subject to the same evolutionary forces: ideas must reproduce (spread), and compete to survive, or risk extinction. I don't see that reason can be said to outshine evolution since they seem to be inseparable. Reason is a product and tool of evolution (just as DNA is). Reason itself may even use evolutionary processes. And in the end, everything, including the ideas and inventions created by reason are still bound to the general rules of evolution. As an example of my point: We might say books outshine clay tablets by far, but we can't books outshine methods for preserving and communicating information. Similarly, we might say that neurology outshines DNA, but we can't make the leap to saying neurology outshines systems for adaptation. Both neurology and DNA are systems for adaptation. Therefore, I think it is more accurate to say reasoning has accelerated the process of evolution. Many things have similarly accelerated evolution: RNA, DNA, sexual reproduction, increased diversity of species, neurology, language, writing, printing processes, computers, the Internet, Google, etc. In the future, we can expect AI, mind uploading, super conductors, etc. to further accelerate the rate of change.
