Harvard says monkeys unable to master grammar crucial to language
I suppose we're going to have to give up on all those monkey applications to college in the future. According to this Harvard University Gazette story:
Nonhuman primates are unable to grasp a fundamental grammatical component used in all human languages, researchers at Harvard University and the University of St. Andrews in Scotland reported recently in the journal Science. Their work provides the clearest example to date of a cognitive bottleneck during the evolution of human language, suggesting a sharp limit to animals' capacity to generate open-ended communication and possible restrictions on other domains of thought.
