Well, it’s obviously both/and with trade-offs between.  

 

Please see attached.  It’s short.

Dave, I found this in Wikipedia:  "The social brain hypothesis was proposed by British anthropologist  <https://en.wikipedia.org/wiki/Robin_Dunbar> Robin Dunbar, who argues that human intelligence did not evolve primarily as a means to solve ecological problems, but rather as a means of surviving and reproducing in large and complex social groups."

 

That might explain why we are now leading our species off the cliff.

Can human beings evolve?

Was reading about Pepper Moths in England during the Industrial Revolution. (population genetics)

Population was white with dark spots and the occasional dark colored moth was easy prey.
Pollution killed lichen and caused the trees (moth's habitat) to be covered in soot, turning them dark.
Population of black moths went from 2% in 1848 to 95% by 1895.

Is is possible for humans to evolve in response to climate change in a similar way? more general prevalence of melanin, craving for spicy hot food?

Of course moths used many generations to achieve their change and their lifespan is a fraction of a humans, so extinction is more likely than adaptation. But, is it at least possible in principle?
