Still evolving. But I wonder in what way? It wouldn't surprise me to
find we are becoming less intelligent as a species. For one thing, with
the rise of agriculture mass starvation of whole broad populations
became possible. More highly energy using brains might be at a
disadvantage in some circumstances. These days at least, more
intelligent people don't have more kids, in the advanced countries
anyway.
