The answer is apparently in our “hairy” ancestors. Millions of years ago, they started to explore underwater to catch small fishes and crustaceans. According to a research carried on observing chimps and published on the Journal of Human Evolution, these animals were looking for a more equilibrated diet in order to grow and to enhance brain activities. That’s why they started to catch small crabs to find a proteic alternative to ants and the usual vegetarian diet. Interesting fact, fishing monkeys were seen only in areas close to rivers or lakes. Nothing similar had been spotted in the rainforest until now.
