The not-so-secret life of plants

From the perspective of Western science, plants have long been considered unaware, passive life forms; essentially, rocks that happen to grow.  But there’s something in the air in the world of plant science. New research suggests that plants are aware of the world around them to a far greater extent than previously understood. Plants may be able to sense acoustics, communicate with each other, and make choices… all this without a brain. These findings are fueling a debate, perhaps even a scientific revolution, which challenges our fundamental definitions of life, intelligence, and consciousness.

He studied electrical signaling in plants and argued that plants use language. Read about his life and work in Orion. This is the now famous study by David Rhoades. Rhoades was derided for his “talking trees” theory, and only was proved correct after his death. Here’s an audio story which goes deeper on Rhoades. Lilach Hadany, the scientist who likened a field of flowers to a “field of ears,” also recently found that plants produce sounds when stressed. The study which found that plants respond to the sound of caterpillars chewing, a collaboration between Rex Cocroft and Heidi Appel. The organization of the octopus nervous system is fascinating.   CREDITS Outside/In host: Nate Hegyi Reported, produced, and mixed by Justine Paradis.
