Evolutionary explanations of sleep

?
Outline 4 evolutionary explanations of sleep
1. Energy conservation 2.foraging requirements 3. Predator avoidance 4.waste of time
1 of 5
Commentary on energy, foraging and predation
Compare sleep habits across species. Zeppelin: small Animals-high metabolic rates-sleep more. Alison- animals with high predation risk sleep less, rabbits are an exception. Capellini says energy conservation hypothesis is wrong, pred/foragrightj
2 of 5
What is the combined approach for sleep.
Sleep should have 2 functions: occupying unproductive hours and energy conservation. Horne: core and optional sleep
3 of 5
Outside cappellini's study for mammalian sleep
Collected data from procedures that were standardised and used land mammals. Found: small mammals with high metabolic rate slept less (does not support) is a link between foraging and sleeping

What is the phylogenetic signal?
The similarities in behaviour between closely genetically related individuals
