According to Primatology.net (a sister site to our friends at Anthropology.net) a study by Ohio State University has found that so-called “enculturated chimps” have enhanced “cognitive abilities, as measured by their ability to understand how to rake” compared to other chimps.
Yes, you read that right–raking. But it’s actually a really clever experiment. And, anyway, there’s nothing wrong with getting some free yard work out of it. As we all know, chimps love nothing more than landscaping.
