16. 2nd Explanation
Where we present a 2nd Hypothesis on the obsure reasons that may have lead the Portuguese to call «Jogo do Galo» (Game of the Cock) to the Game of the Cock in wich we show how the Game of the Cock may easily transform itself into a Cock. As we can see, it is just a question of acquisition of Beak, Crest, Feet, Tail, Feathers and Eye.
Beak can be acquired simply by a slight deformation, Crest by simple expansion of the mark of the 1st Player , Tail by means of expansion, deformation and slight translation while the Feathers are obtained by acquisition of two lateral appendices. Finally, the Eye is obtained simply by moving the mark of the 2nd Player.
