Instinto de agir como polícia teria surgido já na
espécie humana.
Conclusão é de grupo de pesquisa da Alemanha.



Os chimpanzés têm como hábito interferir nas brigas uns dos
outros. No entanto, quando um chimpanzé flagra algum colega roubando um
alimento que não é seu, essa “polícia animal” simplesmente não faz nada a
respeito. A conclusão é de um estudo publicado nesta semana pela “PNAS”, a
revista da Academia Nacional de Ciências dos Estados Unidos.

Isso mostra, segundo os autores, que os parentes mais
próximos do ser humano não se envolvem em punições a terceiros. Essa
característica, evidente entre os seres humanos, teria surgido depois, em algum
ponto da evolução em que chimpanzés e humanos já estavam em ramos diferentes.

1. Qual seria a hipótese para o surgimento de novas características
ao longo da evolução?
