Evolution: Fruit Fly Clocks on the Edge.
Fruit flies evolved in tropical regions under stable light-dark cycles. However, their photosensitive circadian clock had to adapt to extreme seasonal photoperiods during their colonisation of temperate regions. This was achieved by changing the neuronal expression of two key clock-related components.
