There are epigenic markers in monarch DNA for migration patterns? That would entail an Earth map......................So that is not happening. The fact is that no one knows how this is happening, and no one is even seriously looking at it, because this will rewrite every textbook as it proves we do not understand what DNA is, and that being said since we are forged out of DNA we can not know what we are. The answer is very machine like, even using electricity to power our CPU, the human brain, that creates other CPU's also needing electricity
Possibly. No, it would not entail a map.
Yes, they are studying butterfly migration (see below).
You are a fucking retard. It's not going to rewrite every textbook. It's certain to add to our understanding of evolution but these changes are still too modest and inheritability too limited to explain much.

The maiden voyage of migratory monarch butterflies suggests that there is either a genetic basis to the migration or an epigenetic one, because it is possible that all generations of the migratory populations – spring and summer– are capable of being migrants if exposed to the appropriate environmental stimuli. Epigenetic events triggered in migrants leading to the migratory state could involve DNA methylation or histone modification. Genetic or epigenetic mechanisms would both lead to differences in gene expression levels between migratory and summer butterflies.
