Another thing to consider here is that as we progress with technology (specifically medical), we slow down human evolution. The last major evolution our species has experienced is lactose tolerance. Our evolution has significantly been shifted to a social level and that is currently evolving inversely to our physical evolution.

I would argue that if there is any intelligence to any mechanism of evolution, it is some dwell point or singularity in the future that is drawing us in.

In this case, evolution is a means to an end, being intelligence. Once acquired, intelligence becomes a feedback loop that accelerates evolution until the very definition of evolution must evolve.

We now have completely new organisms that feed on human activity otherwise known as institutions. Religions, governments, and more recently corporations have transformed our landscape and continue to evolve. These institutions are where nearly all evolution related to humans is currently proceeding.
