Are we undermining our own evolution?
pasbesoin: I'd just point out that it depends in part on the time scale you apply.  If things get "dumber" for a while, a compensating circumstance is likely to arise.  Whether you view it as positive or negative is subjective; it will occur.I don't take that on faith.  Rather, it's my prediction based on all the historical and scientific data and analysis we've accumulated.What gives me some hope for our current circumstances and our own species, is that so far, as education and affluence rise, birth rates drop.  If we can use this to mitigate the pressure of increasing population against dwindling resources (including the health of ecosystems), perhaps we can reach a sustainable existence with regard to the earth and its ecosystems.  Our species' evolution will continue, but hopefully in a sustainable fashion.Life has shown itself to be very pervasive, at least on this planet.  If we fill the world up with radiation, heavy metals, organic toxins, and whatnot, some forms of life will adapt to cope.  But I'd prefer that there not be such a large set back.  Not another "great extinction".  Life on the planet has reached an interesting level of complexity.  I'd rather see that continue on without interruption.  But then again, that is merely my subjective preference.
