What effect, if any, did you find humans have of on lifecycles? I.e cities tend to be warmer so they butterfly’s lived longer? Or something.

How close together where these different lifecycles? Is it sudden and side by side (one population in the forest and the other in the field next to it) ? Or is it a gradual change over many kilometres?

Edit: Also what are Circadian clock genes?

Thanks mate, that’s a real clear cut answer. And fascinating!
