Machine learning offers insights into evolution of monkey faces, researchers find Computers are able to use monkey facial patterns not only to correctly identify species, but also distinguish individuals within species, a team of scientists has found. Their findings, which rely on computer algorithms to identify guenon monkeys, suggest that machine learning can be a tool in studying evolution and help to identify the factors that have led to facial differentiation in monkey evolution. "Studying the cues that species use to discriminate each other often poses a challenge to scientists," explains James High am, an assistant professor of anthropology at New York University and one of authors of the study, which appears in the journal Proceedings of the Royal Society B . "Many species are now rare and, in the case of these particular monkeys, they live high in the rain forest canopy, so are very difficult to reach." "Driving our study was the premise tha...
