Cohen's argument
This quote from the article:
Cohen’s position implies that while a human being with the mental capacity of a mouse has full moral standing, a mutant chimpanzee with an I.Q. of 150, who regularly contributed articles on philosophy to Wikipedia, would have no rights whatever.
seems a little POV for me. While it could be argued that the above is true, I don't think the article should simply state it as fact. It could equally well be argued to be false (eg, a mutant chimpanzee would be a different kind to normal chimpanzees and so could have rights, and a non-mutant chimpanzee would not have the linguistic abilities to contribute to wikipedia or the moral concepts to be a moral being, however intelligent). Perhaps it should say that that is an objection to his view, rather than an actual problem with it. I don't like to edit articles myself, I am an anonymous newbie.
