cara esse bixo é domesticável? ele faz igualzinho meu pitbull mano, ele deita de barriga pra cima pra tu mexer com ele, se vc para de coçar a barriga, ele morde sua mão, mas é impressionante como ele sabe a pressão exata de morder sem machucar. pra ter uma idéia da pressão da mordida, ela reduz um femur de boi de 50cm, a 10cm em menos de 3 dias. muito doido. |

http://en.wikipedia.org/wiki/Domesticated_silver_fox Conforme os caras selecionam pra cruzamento as raposas mais dóceis, mais aparecem alguns traços típicos de cachorro nelas (orelha caída, cauda felpuda). Esse experimento demonstrou concretamente que há relação entre fenotipo e comportamento "As Lyudmilla Trut says in her 1999 American Scientist article [1], The least domesticated foxes, those that flee from experimenters or bite when stroked or handled, are assigned to Class III. Foxes in Class II let themselves be petted and handled but show no emotionally friendly response to experimenters. Foxes in Class I are friendly toward experimenters, wagging their tails and whining. In the sixth generation bred for tameness we had to add an even higher-scoring category. Members of Class IE, the "domesticated elite," are eager to establish human contact, whimpering to attract attention and sniffing and licking experimenters like dogs. They start displaying this kind of behavior before they are one month old. By the tenth generation, 18 percent of fox pups were elite; by the 20th, the figure had reached 35 percent. Today elite foxes make up 70 to 80 percent of our experimentally selected population." |
