Evolution Flashcards
What did Allison and Ciccotti find
predators sleep morw
What is a problem with Allison and Ciccotti’s research
Carnivores also sleep more so there is no cause and effecn
What did Lee and Martin find
koala bears slept for 19 hours due to low nutrient intake
What is a problem with Lee and Martin’s research
It’s unfalsifiable because sheep only sleep for 3 hours
Compare restoration theory with evolutionary theory
Restoration theory suggests sleep is needed to maintain a constant physiological state but evolutionary theory suggests sleep is not needed and not adaptive
Why do both theories have issues
Restoration theory is reductionist and Evolutionary theory lacks explanatory power in terms of states and functions of sleep
what does ECT (webb) suggest
energy is conserved when you’re asleep as it is inefficient to be awake so sleep is adaptive
what does predation theory (meddis) suggest
sleep provides safety
what does threat simulation theory (revonso) suggest
REM sleep is important for practicing threat responses
