Elevated sleep need in a stress-resilient species.

Sleep is broadly conserved across the animal kingdom, but can vary widely between species. It is currently unclear which types of selective pressures and sleep regulatory mechanisms influence differences in sleep between species. The fruit fly has become a successful model system for examining sleep regulation and function, but little is known about the sleep patterns and need for sleep in many related fly species.

Many scientists have argued that the science classroom is no place for discussion of creationism. When I began teaching I did not teach creationism, as I focused instead on my areas of expertise.
