While researching her doctoral thesis, Suzanne Simard, now a professor of forest ecology at the University of British Columbia, made an astounding discovery – trees in forests seem to possess complex information superhighways in their root systems that allow them to share information. Her 1995 doctoral thesis on the topic has been part of a revolution in how scientists view plants, leading many to suggest that they possess cognitive abilities, and even intelligence. This animation from TED-Ed details the symbiotic relationship – between tree roots and fungi called mycorrhizae – that serves as the foundation of these intricate intra-tree communication networks, allowing them to trade news on topics such as drought and insect attacks, and even detect if an incoming message has been sent by a close relative.
