Study shows chimps able to understand needs of others

By setting up a unique experiment, a small team of researchers has found that chimpanzees are able to understand need in other chimps, despite their general disinclination to offer aid when they see it. Shinya Yamamotoa, Tatyana Humleb, and Masayuki Tanakac set up a way to test their idea that chimps are able to understand some part of what is going on in the minds of others around them, and as they describe in their paper published in the Proceedings of the National Academy of Sciences, they found a way to demonstrate it.
