No doubt. In rain forest and isolated volcanic craters. But not primates. There are no undiscovered primates. If there were, we would have found biological evidence by now. Hair, bones, feces...something. Sorry guys, but bigfoot and Ariel do not exist. Nessie might, but if and when it is discovered, it will probably be a disappointment and not live up to its billing.
I know I am feeding the troll, but they found a new primate in the Congo less than a year ago. You are seriously sounding like that idiot who closed the patent office.
