Lethargus Is A Caenorhabditis Elegans Sleep-Like State, Nature
 









Excerpts: There are fundamental similarities between sleep in mammals and
quiescence in the arthropod Drosophila melanogaster, suggesting that sleep-like
states are evolutionarily ancient. The nematode Caenorhabditis elegans also has
a quiescent behavioural state during a period called lethargus, which occurs
before each of the four moults. (...) suggest a common genetic regulation of
sleep-like states in arthropods and nematodes. (...)  sleep may have evolved to
allow for developmental changes.
