genetic data

Colonies of ants began growing mushrooms when an asteroid hit Earth 66 million years ago. This damage caused mass extinction but also created ideal conditions for fungi to flourish. This is how an evolutionary partnership was created that became even closer 27 million years ago and continues to this day. Credit: Don Parsons

Ant farming began 66 million years ago following the asteroid that doomed the dinosaurs

Smithsonian Institution scientists compiled and analyzed an extensive genetic database, and found that some mushroom crops became completely dependent on ants 27 million years ago, a process created 65 million years ago by an event
