Deers, are a playful animals, they hop and dance and run fast, run, run, run through the forest. The incidence is that animals are perceptive, but perceptive does not mean they see with the eyes only, no perceptive, means they have motor skills, they defend, they scan, they, recongnize.
So animals in short have cognition and motor skills.
As SPECIES: Odocoileus virginianus
fawns, so as to test predictions associated with these two hypotheses. Consistent with the motor training hypothesis, play peaked early in life (≤3 weeks), which should coincide with development of the cerebellum and motor skills. These closely related species differ in antipredator tactics, so we predicted that they should display different motor patterns during play if it serves a motor training function. Although some characteristics reflected species-typical antipredator tactics (e.g. more ‘signal bounds’, leaps with long and high suspension, in white-tailed deer; more social play in mule deer), both species engaged in a similar amount of fast travel and similar rates of turns, traits that we expected to differ in line with their antipredator tactics. Consistent with the self-handicapping hypothesis, fawns of both species displayed high rates of nonfunctional manoeuvres, which were similar in form. However, these maneuvers did not become more common as the fawns aged as expected if these help to develop the prefrontal cortex and cognitive skills. Our results suggest a refinement and blending of both hypotheses. Juveniles may play to develop similar motor skills rather than species-typical antipredator tactics, with nonfunctional maneuvers to further promote the development of cognitive and motor skills during the early juvenile period.
