Thank you for your considered and thought-provoking response.

“Headwind to evolution” implies that evolution has goals which it is “trying” to achieve. I see evolution as a random process determined by the physical characteristics of the earth/universe not as a problem solving mechanism. Random mutations and events provide a survival or reproductive advantage so a particular organism thrives. If the advantage is a big one then that lineage comes to dominate its ecological space. Do you think evolution has a goal?
