I don't really understand why you guys are disputing this. Help me?
It appears that both studies show that the species evolved from primarily light to mostly dark. The question is "why did they change?"
But there are also some other things that would be nice to know. How do the two varieties appear under ultraviolet light?
Was there predation of the lighter moths that opened a nitch that could be filled by immigration of a dark population from surrounding areas?
Is there some difference in susceptibility to pollutants in the urban environment between the two varieties?
I don't think we really have the HOW down yet. But both studies seem to support the what happened portion of the question.
