Monkey see, monkey do; but who exactly do monkeys watch to learn how to act? Scientists have found that for young vervet monkeys, mom is the role model, The New York Times reports. Researchers gave the primates grapes that were covered in sand and watched as the infants each adopted their own mother's way of cleaning and eating the fruit, according to the results published in the April issue of Animal Behaviour. Techniques included dusting the grapes off with their fingers and opening them up and just eating the juicy insides.
