<br>
Was reading about Pepper Moths in England during the Industrial Revolution. (population genetics)<br>
<br>
Population was white with dark spots and the occasional dark colored moth was easy prey.<br>
Pollution killed lichen and caused the trees (moth's habitat) to be covered in soot, turning them dark.<br>
Population of black moths went from 2% in 1848 to 95% by 1895.<br>
<br>
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?<br>
<br>
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?<br>
