The interrelationships between sleep, ecological, and constitutional variables were assessed statistically for 39 mammalian species. Slow-wave sleep is negatively associated with a factor related to body size, which suggests that large amounts of this sleep phase are disadvantageous in large species. Paradoxical sleep is associated with a factor related to predatory danger, which suggests that large amounts of this sleep phase are disadvantageous in prey species. 

Factors relating to energy conservation during sleep in mammals.

It is proposed that sleep may serve a prime role as an energy conserver and immobilizer in the smaller and more primitive mammals, with REM sleep being particularly oriented to this purpose. However,

Sleep viewed as a state of adaptive inactivity

It is proposed that sleep is best understood as a variant of dormant states seen throughout the plant and animal kingdoms and that it is itself highly adaptive because it optimizes the timing and duration of behaviour.

different between mammalian species

The comparison of mammalian species has revealed striking similarities in the way sleep is regulated which indicates common underlying mechanisms of sleep function.

SLEEP IN MONOTREMES; IMPLICATIONS FOR THE EVOLUTION OF REM SLEEP

NonREM sleep alternates with periods of REM sleep, characterized by rapid eye movements, EEG desynchrony, hippocampal theta, ponto-geniculo-occipital (PGO) spikes, twitching, autonomic irregularity and muscle atonia.

Behavioral phenomenology of sleep (somatic and vegetative)

The foregoing analysis of behavioral sleep phenomenology shows that the most significant factual and theoretical aspects of sleep can be logically organized only according to several criteria, it

A quantitative, theoretical framework for understanding mammalian sleep

A general, quantitative theory for mammalian sleep that relates many of its fundamental parameters to metabolic rate and body size is developed and leads to predictions for sleep time, sleep cycle time, and rapid eye movement time as functions of body and brain mass.

Results can be explained by a theory of kinetics of fetal growth based on three hypotheses: the brain is the slowest-growing organ in the fetal mammal; it is also the pacemaker for growth of other tissues, which are held to its rate of growth; and brain growth proceeds at the maximum rate allowed by its intrinsic growth law.
