Ant agriculture began 66 million years ago in the aftermath of the asteroid that doomed the dinosaurs
According to a new study, colonies of ants began farming fungi when an asteroid struck Earth 66 million years ago. This asteroid impact caused a global mass extinction but also created ideal conditions for fungi to thrive. Innovative ants began cultivating the fungi, creating an evolutionary partnership that became even more tightly intertwined 27 million years ago and continues to this day.
