A walk in the woods; the evolution of dogs and the future of humans

Today the temperature hovered around freezing and I took the dog out for a walk of a few miles in the town forest. The air was crisp and cool and a little chilly at the start. As the dog and I walked on my temperature rose, hat came off and coat was unzipped but later in the shade I bundled up again. The dog always starts pulling at the leash but as the miles pass it tends to lag behind. I don’t have to pull her but I don’t have to pull her back either. It had rained yesterday so there was a crust in some places but in general the going was easy.

I was reading about the dog genome and estimates that they were domesticated tens of thousand of year ago. The canines have been with us for a long time and it is sobering that we have changed their configuration so much in such a short time. This is one plastic genome. What will happen in our future as we gain the ability to modify our own genome for cosmetic purposes? Will blonds predominate? Will the average bust size increase? Will we have hermaphrodite appear with both male and female genitalia? Some gays are trying this through surgery today. It will soon be possible to create true test tube babies freeing women forever from the pain and discomfort of child bearing. This will allow women to drink and get stoned without affecting their fetus developing in a distant laboratory. Will convenience win? Where will it go?
