Should this really be so strange? After all, at various levels above the genetic, from temperature regulation and damage repair to fighting or fleeing, organisms exhibit an array of mechanisms for sensing their environment and adjusting their response to it. The suggestion here is that the principle of sensing and control extends down also to the genetic level, where genes can be turned on and off to activate already-existing program modules, enabling an organism to live efficiently through short-term changes in its environment. Nothing in the genome changes. The program is set up for the right adaptive changes in the phenotype to occur when they are needed. |
We could probably test this by comparing the genetic code prior to the alleged speciation with the genetic code post the speciation. Either way - a fascinating idea. One quick example that comes to my mind is how animals adjust their fur covering to account for the temperature - i.e., they bulk up in the winter and then they shed in the summer. Also, note: this site claims that the book is a work of fiction (somewhere, I think) - but the KTSC book is not written as a work of Sci-Fi - for example, there are a bunch of references to people who I consider to be "legitimate" pro-ID authors. On the other hand, the main BAEN site seems to be totally devoted to science fiction stories.
