The Desert Mermaid

When I visited a game reserve in South Africa, we had our meals outside on a little veranda. They brought all the usual things - sugar for tea and coffee, butter for bread, et cetera. But the butter and sugar specifically were in heavy stone containers with heavy stone lids. They did that because if the butter and sugar were in lighter containers, the vervet monkeys would sneak in, steal both items, take them down next to the river, mix the two together, and then eat it. So, the desire to mix things to make it better seems to go back to pre-human primates at least - the monkeys - at least those specific monkeys in South Africa - clearly know that the fat and the sweet are much tastier (and probably easier to consume) when combined.
