On the other hand, HVAC (I mean, that's what it is right?) must confer a huge advantage, even in its relatively early and primitive stages. You probably save loads of energy with even a degree in the right direction, especially when you're raising lots of larvae. Like the first critter to evolve a couple of photosensitive cells, it seems like a minute thing, but telling dark from light can be a huge leg up. Now we look at complex eye structures and are amazed, but of course they were once eye spots. I suspect that it might be the same with the termites, who have after all had a long time, and uncountable generations to select for these traits. No less remarkable for all of that though.
