6. AO2: general support for the evolutionary approach comes from who that found mammals with similar genes have similar sleep patterns

Horne (1998)
Siegel (2008)
7. AO1: Sleep is a period of inactivity which is important for warm blooded animals who use lots of energy maintaining body temperature and for small mammals with a high metabolic rate.This refers to which evolutionary explanation?
Energy conservation
Waste of Time
Foraging requirements
Predator avoidance
8. AO2: Zepellin an Rechtstaffen (1974) found that small animals with a higher metabolic rate sleep more than large animals. This supports?
the waste of time explanation
the predator avoidance explanation
the energy conservation explanation
the foraging requirements explanation
9. AO1: Herbivores eat food with low nutrient content so have to eat more. Carnivores eat food with a high nutrient content so don't have to eat as often. This effects how long they can sleep for. This refers to which evolutionary explanation?
Waste of Time
Energy Conservation
Foraging Requirements
Predator Avoidance
10. AO2: Capellini (2008) looked at previous studies with standardised procedures and found that animals who sleep in exposed positions sleep less. This supports which explanation?
