n'en faut point d'autre preuve. Il suit donc sa
raison en se donnant au plaisir »

Sleep

For Rial et col. The evolution of awakening is the main force towards a development of the brain.Cortical awakening is specific to mammals, as well as sleep with its two states (slow wave sleep, spindles and ‘rapid’ sleep ).
Reptiles possess a wake slow EEG(with spindles) in the whole brain.
Amphibians, without cortex, don’t show any sign of sleep.

Play
For Burghardt, is an activity
- incompletely fonctional (useless on first sight),- volontarily initiated (which implies intention and, for him, pleasure),- non serious,- repetitive,- when the subject is completely relaxed.

Burghardt recognizes it without ambiguity- in mammals, - in birds - in reptiles.
