The 'daywake' gene is linked to afternoon naps in flies
The afternoon siesta-suppressing gene discovered - interesting science news

Researchers working on fruit flies have identified a siesta-suppressing gene which could inform us on the biology that helps several organisms including humans to balance the benefits of a good afternoon nap vs. getting important things done.

The afternoon naps which occur more on intense warm days were probably evolved as a protection against exposure to hot temperatures in the afternoon. However, certain fruit flies have a gene called ‘daywake’, which suppresses this activity especially when the temperatures cool down to increase the time spent seeking mates or food.

Interestingly, the ‘daywake’ gene is adjacent to the ‘period’ gene which controls the circardian rhythm or the sleep-wake cycle of these flies.
