-Ethnicity is a non issue.
-Increased technlogy lowers the birth rate of a given socierty.
-Increase technology keeps deliterious genes in a given population with without changing any other gene densities as a trade off.

Okay, so you could have said that a little more politely, but we'll move on. This is not a direct reply to Ghostiger, but I didn't know where else to jump back in.

My point originally probably got lost in how I was trying to say it. I'll concede that remaking one's environment could be considered a successful adaptation by a species (it works for beavers right?), however, the total domination of the environment (with the exception of natural disasters) perpetrated by the human race serves to remove evolutionary pressures. It has been my understanding that the mechanism "natural selection" is based on comparing developed variation against environmental pressure, those that prosper in the face of pressure are "selected" to reproduce, strengthening their contribution to the the genetic line of the species. In a setting where environmental pressure is removed, many genotypes, both adept and inept, go untested and are propogated to following generations.

Take eyesight for an example. Through much of the world, corrective lenses are available for those with poor eyesight. In many parts of the world, visual acuity is not tested as it was thousands of years ago. Variation in acuity (both positive and negative) increases over generations because the trait is untested. My statement that the species is weaker because of this may have been to strong: my conclusion is that the possibility of survival for weaker individuals is increased because environmental pressure is substantially decreased.

To Occhi, yes, I stopped going to church a few years ago, and don't plan to go back. However, I am planning to see the Rabbi in the next few weeks when Passover rolls around.
