If you are interested in finding out about the latest developments in evolutionary developmental biology, I suggest you consult journals on the subject. When you can actually come up with a question, let us know.
Sorry mate, but I am in agreement with Hercules Rockfeller here. Seriously, this is a great feild and one which all of us here in this convo love, but PLEASE can you post a specific question since you posted the thread in the first place and thus act as a sort of director of any potential discourse.
Cheers mate.
what puzzles me how does a moth, that does not have the colour of the enviroment or the colour or pattern to avoid predation , know to change its colour and/or pattern to avoid predation , based on a moth that does ?
how does this happen ?
how does a moth with a minute brain( or nervous system really ) become aware of another moths survival advantage ?

Natural selection. What happens is that moths tend to look alike, but every so often some are born looking different. If these differences lead to even a slightly higher rate of reproduction, the genes for these differences will become more numerous in the gene pool.
The field of evolutionary developmental biology deals with developmental questions. In other words, it deals with embryonic development. It compares the developmental processes of different animals and plants in an attempt to determine the ancestral relationship between organisms and how developmental processes evolved. The discussions in this thread to date have concerned straight evolutionary biology, not evo-devo.
