I stand by my comments re 80% of the knowledge, as it is fact, and Monkey Forest actually has made a massive contribution to make to the scientific knowledge, which can not be underestimated. And the Gibraltor Macaques are not a accurate representation, they have their contribtutions to make however the amount of human contact they have is so far removed from their wild counterparts that it makes Monkey Forests data also valuable.
People on here seem very fired up about this and my comments, but I was merely giving my opinion, I did not state any 'facts' which were not true and I'm not saying everyone should go to Monkey Forest but if you are in the area then its worth going.
I'm with taun here - that 80% is a big claim and I can't accept it as truth unless you can back it up with something (in which case I shall humbly withdraw my objections to the statement!).
