Exploring plant intelligence challenges traditional views, with Dr. Paco Cavo discussing the intelligence of non-neural organisms. Transitioning from philosophy of science to plant behavior, Dr. Cavo sheds light on Charles Darwin's botanical observations and the significance of mental effort in perception. Emphasizing the need for evidence-based understanding, the book 'Plantus Sapiens' delves into the controversy of plant intelligence.
Examining plant anesthesia reveals key insights. By ceasing normal behavior under anesthesia, plants showcase unique responses upon awakening. This phenomenon, illustrated by the Venus flytrap and sleeping beans, challenges assumptions on plant reactivity. The shared sensitivity to anesthesia across various life forms prompts reconsideration of plant behavior and adaptation.
Perceiving plant intelligence through an ecological lens calls attention to relational properties. As plants respond adaptively to environmental cues, internal and proprioceptive awareness shape their behavior. From circadian rhythms to melatonin production, plants utilize shared molecules for information processing. Integrating physiological and electro-chemical cues reveals the complexity of plant behaviors beyond surface manifestations.
Plants exhibit unique offline cognition where they can reorient themselves overnight to anticipate the sun's position in the morning. This offline competency challenges the notion of intelligence solely tied to online cognition. Different plants display varying degrees of reorientation, using different parts of their anatomy. The ability to predict and prepare for future conditions showcases an adaptive and goal-directed behavior that goes beyond immediate responses.
Poco Calvo challenges misconceptions about plant intelligence by highlighting their information processing abilities without neurons. He emphasizes the significance of embodied cognition, suggesting that cognition extends beyond neural machinery to involve the body and environment. While the absence of neurons may seem limiting, plants utilize signaling molecules and exhibit circadian rhythms akin to animals, implying an intricate form of intelligence rooted in their evolutionary history.
This month we have an intriguing interview with Dr. Paco Calvo from the Minimal Intelligence Laboratory at the University of Mercia in Spain. We talk with him about his new book Planta Sapiens: The New Science of Intelligence.
We discuss the scientific evidence for plant intelligence while acknowledging that intelligence and consciousness are not the same. It is interesting to think of plants as demonstrating embodied cognition in contrast to the "intelligence" demonstrated by computer software. We also consider the pioneering work of Charles Darwin, who actually studied plant behavior before the invention of time lapse photography.
