The sleep patterns of jellyfish and sea anemones share similarities with those of humans, according to research published in Nature Communications. The findings support the hypothesis that sleep evolved across a range of species to protect against DNA damage. 🧪
DNA damage modulates sleep drive in basal cnidarians with divergent chronotypes - Nature Communications
Here, the authors use the diurnal upside-down jellyfish and the crepuscular starlet sea anemone as simple nerve net models to examine the potential evolutionary origins of sleep. They describe and define sleep patterns in these species, finding that sleep deprivation increases neuronal DNA damage and that sleep facilitates genome stability.
