Knowledge about sleep comes primarily from research on mammalian species, whose daily sleep quotas range from 4 to 19 hours, with rapid eye movement (REM) sleep occupying 10% to 50% of this time. Findings of REM sleep or elements of it in monotremes have filled a gap in its evolutionary history. To some, this suggests that REM was inherited from reptiles, although the absence of REM in living reptiles casts doubt on this view. The function of sleep remains controversial.1 On one hand… Expand

TLDR
It is proposed that the risks and opportunity costs of sleep are responsible for shorter sleep durations in humans, with risks arising from terrestrial sleep involving threats from predators and conspecifics, and opportunity Costs because time spent sleeping could be used for learning, creating material objects, and socializing. Expand
Phylogenetic Analysis of The Ecology and Evolution of Mammalian Sleep
TLDR
It is found that basal metabolic rate correlates negatively rather than positively with sleep quotas, and that neither adult nor neonatal brain mass correlates positively with REM or NREM sleep times, which contradict hypotheses that invoke energy conservation, cognition, and development as drivers of sleep variation. Expand
Sleep intensity and the evolution of human cognition
TLDR
It is proposed that humans are more efficient in their sleep patterns than are other primates, and that human sleep is shorter, deeper, and exhibits a higher proportion of REM than expected. Expand
The cost of deep sleep: Environmental influences on sleep regulation are greater for diurnal lemurs.
TLDR
It is proposed that sleeping site security was an essential component of sleep regulation throughout primate evolution and may have been an important factor associated with the evolution of sleep in early and later hominins. Expand
Sleeping outside the box: electroencephalographic measures of sleep in sloths inhabiting a rainforest
TLDR
The first electroencephalogram (EEG) recordings of sleep on unrestricted animals in the wild using a recently developed miniaturized EEG recorder are performed, and it is found that brown-throated three-toed sloths inhabiting the canopy of a tropical rainforest only sleep 9.63 h d−1, over 6 H less than previously reported in captivity. Expand
Energetic constraints, not predation, influence the evolution of sleep patterning in mammals.
TLDR
Neither sleep-cycle length nor phasing of sleep was significantly associated with three different measures of predation risk, undermining the idea that they represent anti-predator adaptations. Expand
A phylogenetic analysis of the correlates of sleep in birds
TLDR
The first quantitative analysis of sleep in a non‐mammalian taxon (birds) focusing on the daily amount of time spent in slow‐wave sleep (SWS) and rapid‐eye movement (REM) sleep as determined by electrophysiological methods suggests that further insight into the function of sleep across the animal kingdom may require an expansion of sleep research beyond the current mammalian paradigm. Expand
Clues to the functions of mammalian sleep
The functions of mammalian sleep remain unclear. Most theories suggest a role for non-rapid eye movement (NREM) sleep in energy conservation and in nervous system recuperation. Theories of REM sleepExpand
Sleep: Evolutionary and Adaptive Changes in Birds and Mammals
TLDR
This chapter discusses the sleeping patterns, sleep strategies, and sleep consolidations across phylogeny and aging, which are essential for the current challenges in their society, where the authors experience poor sleep quality and insufficient sleep and they wake up tired almost every day. Expand
Why REM Sleep is Reduced in Aquatic and Semi-aquatic Mammals? A Discussion of the Possible Theories
Although most mammals experience rapid eye movement (REM) sleep, the primary function of REM sleep is still debatable. Current data show that aquatic mammals have absent or reduced REM sleep and thatExpand

The ontogeny of mammalian sleep: a reappraisal of alternative hypotheses
TLDR
Critical review of this evidence indicates that REM sleep may not be present at birth in newborn altricial mammals; rather, it appears that all mammals early in development exhibit spontaneous, dissociated activity that progressively becomes organized into the distinct states of REM and non‐rapid eye movement sleep.

Sleep in mammals
Abstract Quiet sleep (QS) was correlated with a different set of constitutional variables from those associated with active sleep (AS), in a sample of 69 species of mammals. The time spent in quietExpand

TLDR
It is proposed that sleep constitutes a period of dormancy in which energy is conserved to partially offset the increased energy demands of homeothermy and disruptions of circadian rhythms of sleep and wakefulness in humans produce impairments in mood and performance independent of total amounts of sleep obtained. Expand
Sleep as an adaptation for energy conservation functionally related to hibernation and shallow torpor.
TLDR
It is proposed that sleep constitutes another, albeit less well recognized, variation on the theme of mammalian dormancy—that is functionally related to hibernation and torpor, and it is suggested that they are functionally homologous processes. Expand
Sleep in the platypus
TLDR
The findings indicate that rapid eye movement sleep may have been present in large amounts in the first mammals and suggest that it may have evolved in pre-mammalian reptiles. Expand
The REM Sleep-Memory Consolidation Hypothesis
TLDR
The evidence for the hypothesis that REM (rapid eye movement) sleep has an important role in memory consolidation is reviewed and found to be weak and contradictory. Expand

TLDR
The possibility that two fatal sleep-associated syndromes (Sudden Infant Death Syndrome and the Oriental Nocturnal Death Syndrome) may involve deficits of REM was discussed and the mechanism used by the brain to promote and ensure recovery from sleep was discussed. Expand
