Farming

After the age of the dinosaurs came to an end some 65 million years ago, a ‘tribe’ of ants known to scientists as the Attini decided to give up life as hunter-gatherers and become farmers instead. The ants, native to South America, began farming fungus that grew on decomposing wood. This allowed ant colonies to increase in size until 15 million years ago. Humans only came up with the idea of agriculture 10,000 years ago.
