A wise approach going forward would be to find the tools first before making assumptions. Note the gratuitous slur at the end of the media release: “We are so used to trying to prove that humans are unique, that similarities with other primates are often neglected. Studying living primates today may offer crucial clues that have been overlooked in the past.” Sorry, bodkins. We don’t have to do anything to prove humans are unique. The fact that you are studying macaques for a journal while they wreck their teeth on sand and grit demonstrates that fact beyond reasonable doubt. And thoughtful people should be suspicious of UNreasonable doubt.
