Peppered moths, like humans, come in different colours.

And what do you think causes those colours, other than the genome?

There is a difference between a change in the genome and variation
(though
I
take your point that variation could be considered a change).

What do you think causes varation other than changes in the genome?

Nice try. There was no change aiui because both variations already
existed.

Yes, there were already variations in the genome. If there was no
change in genome between black and white variety, there would be no
change in colour between bklack and white variety.

So I am right. Excellent, thanks.
