re: #331 Sharmuta

What I wonder about climate change is if this time man himself isn’t contributing to an environmental pressure that will bring about an adaptation. Are we creating our own evolution?

Medical advancements create a divergence of evolutionary pressure. Conditions that were once fatal or at the least severely limiting, are no longer as much of a barrier to procreation as they have been in the previous eons.

Additionally, cheap travel has created a homogenizing pressure on the species as well. Isolations that had created differentiations over the last several eons no longer really exist. We are all living in the same local now, with little to no barriers to commingling with others who may look different.

We as a species have begun to strongly influence our own evolution in a very dramatic way in the last two hundred years.
