Among mammalian species, the time spent in the two main “architectural” states of sleep—slow‐wave sleep (SWS) and rapid‐eye‐movement (REM) sleep—varies greatly. Previous comparative studies of sleep architecture found that larger mammals, those with bigger brains, and those with higher absolute basal metabolic rates (BMR) tended to engage in less SWS and REM sleep. Species experiencing a greater risk of predation also exhibited less SWS and REM sleep. In all cases, however, these studies lacked… 
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.
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.

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.

History and future of comparative analyses in sleep research
Unearthing the Phylogenetic Roots of Sleep
Evolutionary perspectives on the function of REM sleep
TLDR
In conclusion, assuming that sleep serves an important function, determining how such animals compensate for the loss of a particular sleep state may yield clues to its purpose.
Ecological constraints on mammalian sleep architecture
TLDR
The evidence for how ecological factors, including predation risk and foraging requirements, might shape patterns of sleep among mammals is reviewed and the dramatic differences in sleep characteristics of terrestrial and aquatic mammals provide evidence for the claim that ecology influences sleep architecture.
The origins and evolution of sleep
TLDR
The contributions of classical and emergent genetic model systems to investigate mechanisms underlying sleep regulation are described, highlighting fundamental interactions between sleep and sensory processing, as well as a remarkable plasticity of sleep in response to environmental changes.
Evolutionary Origin of Distinct NREM and REM Sleep
TLDR
The evolutionary origin of the distinct REM/NREM sleep states is discussed to gain insight into the mechanistic and functional reason for these two different types of sleep.

TLDR
The electrophysiological hallmarks of mammalian sleep are often used as the ‘‘gold standard’’ for sleep in nonmammals, while sleep in other vertebrate classes has largely been neglected.

TLDR
The interrelationships between sleep, ecological, and constitutional variables were assessed statistically for 39 mammalian species and found that both constitutional and ecological influences are important predictors of the amount and type of sleep obtained by mammals.
