In today's episode, we’re exploring the incredible story of the Brazil Nut tree—a true giant of the Amazon rainforest.

This towering tree is more than just a source of nuts. It’s a key player in the rainforest’s ecosystem, a symbol of how humans have shaped nature, and now, thanks to groundbreaking research, it’s a genetic marvel that’s giving us new insights into biodiversity and conservation. Special credit goes to Dr. Victor Caetano-Andrade and his team at the Max Planck Institutes for their pioneering research, which forms the foundation of today’s episode.
