Once again, chimpanzees have been the subject of another study on “fairness”. Researchers in Georgia claim they now have “…the best laboratory evidence yet that chimpanzees have a human-style sense of fairness.” Those who have reviewed the study believe the study is flawed and opine that a sense of fairness is uniquely human.http://cosmiclog.nbcnews.com/_news/2013/01/14/16508452-do-chimps-have-a-sense-of-fair-play-study-adds-to-evolutionary-debate
Researchers have wondered how long ago did our ancestors acquire a sense of “fairness”? The latest research, published a few weeks ago, claims that this sense of fairness arose millions of years ago, “… before our ancestors split off from the evolutionary lines leading to other primates.” (Id.) The principal author of the study is Darby Proctor of Emory University’s Yerkes National Primate Research Center in Atlanta. His co-author Frans de Waal, Director of Emory’s Living Links Center said:
“We’ve concluded that chimpanzees not only get very close to the human sense of fairness, but the animals may actually have exactly the same preferences as our own species.”
Other researchers including Keith Jensen of the University of Manchester question this latest study. Mr. Jensen believes that “our sense of fairness is a derived trait and may be unique to the human race.” (Id.)
One of the reasons that Mr. Jensen takes issue with the latest study is due to the results of the “ultimatum game” used in the study:
