Re: MartinV asserts fraud - but does he have integrity?
And to add to the difficulty:
Peppered moths are hard to find For illustrative purposes it was desirable to find both morphs sitting next to each other on the same surface. In an accessible place. With good lighting.
Staging seems the only practical method of producing what was wanted.
Re: MartinV asserts fraud - but does he have integrity?
They usually rest high up in trees, where it is very hard to see them from the ground. So yes, where they rest is very accessible to birds but not to us. And, of course, the "wrong" colour moths for the area would usually be rare, so finding one of each kind side-by-side would be really difficult even now.
Re: Another antidarwinistic hypothesis for industrial melanism
I beleive that Kettlewell's experiments established that birds will eat peppered moths given the opportunity. And wherever peppered moths prefer to rest during the day it is unlikely to be inaccessible to small birds.
Can you suggest how your explanation is supposed to actually work ? And how it explains the results of Kettlewell's experiments ?
