Energy Conservation - 'hibernation theory of sleep'
1 of 9
Zepplin and Rechtschaffen
Smaller animals with higher metabolic rates sleep more longer - exception of the sloth
2 of 9
Alison and Cicchetti
Species with high predation risk sleep for less time - exception of the rabbit
3 of 9
Capellini
Previous research was flawed as standardised procedures were not used. Found that energy conservation was a negative correlation; supports foraging requirements and predator avoidance (exposed/groups)

Meddis
Waste of time - keep out of the way with nothing better to do
5 of 9
Siegal
Energy conservation and predator avoidance as being awake is riskier than sleeping

Alison and Cichetti
NREM conserves energy - larger animals have less NREM but not REM. More primitive animals only have NREM which illustrates that REM evolved for brain activity
7 of 9
Capellini
Phylogenetic signal; behavioural similarities between those who are closely genetically related. Mammilian species have more similar sleep patterns.

Horne
Core sleep = SWS for brain/body recovery whereas REM is optional and for energy conservation.
