I have read that the although the halakha requires koah gever (human strength/exertion) for pouring water over hands for n'ttilath yadhayim but it says explicitly in the Mishna that a qof (monkey) may also validly perform this function (m.Yadhayim 1:5).
Also, I have read that there was a creature called Adhne HaSadhe and that Rabi Yose expressed the view that this creature caused Tumath Ohel just like a human when dead (m.Kilayim 8:5). The Tiphereth Yisra'el on this Mishna states that the Adhne HaSadhe are gorillas.
My question is: "Are we meant to understand by the halakha that primates are considered 'human enough'? Are there other areas where they are considered partially human not mentioned above?"
