DeepSummary
The episode features a discussion with staff writer Zoë Schlanger about her upcoming book 'The Light Eaters', which explores the emerging scientific debate around plant intelligence. Schlanger explains how recent experiments have challenged traditional assumptions about plants, revealing their ability to sense touch, hear, communicate, make decisions, and even recognize kin.
Researchers have found evidence of plants exhibiting behaviors that resemble decision-making, such as counting and storing information, leading to a heated debate within the botany community about whether plants can be considered intelligent. Schlanger highlights the philosophical and ethical implications of this line of inquiry, including the potential for a 'plant rights' movement and a shift in how humans perceive their relationship with the natural world.
While acknowledging the limitations of anthropomorphizing plants, Schlanger argues that the research prompts a humbling realization about humanity's place among other species, unseating the assumption that humans sit atop the evolutionary hierarchy. She suggests that a deeper appreciation of plant vitality and complexity could fundamentally alter human perspectives on the living world around us.
Key Episodes Takeaways
- Recent scientific experiments have challenged traditional assumptions about plant cognition and revealed behaviors that resemble decision-making, communication, and even kin recognition.
- A debate is emerging within the botany community about whether plants can be considered 'intelligent', with profound implications for human cultural attitudes and ethical considerations towards plants.
- Understanding the evolutionary sophistication of plants can promote a humbling realization about humanity's assumed superiority and our relationship to other species.
- The research raises the potential for a 'plant rights' movement akin to animal rights advocacy, while also prompting philosophical questions about consciousness and intelligence without a centralized brain.
- Appreciating plant vitality and cognition could fundamentally shift human perspectives on the living world around us, unseating assumptions of human dominance over nature.
- While acknowledging the limitations of anthropomorphizing plants, the episode suggests that a deeper respect for plant complexity is warranted based on emerging scientific evidence.
- The episode explores the idea that plants may exhibit 'personalities' or individual variations in behavior, akin to observations of animal personalities.
- Physical experiments demonstrate plants can sense and respond to touch, sound, and chemical signals in ways that resemble decision-making more than mere reflex.
Top Episodes Quotes
- “There's some evidence to say that some plants are something like the boy who cried wolf. Like, theyll kind of signal wildly at the slightest disturbance. And other plants are more reticent to do that. Theyll kind of wait for the disturbance to be really bad, for the pests to be really bothering them before they let out their kind of distress call that alerts other plants to there being some kind of pest invasion.“ by Zoe Schlanger
- “Once you start to realize the incredible evolutionary fine tuning that goes into plants, it kind of shifts the ground beneath humanity to settle us a little more among other species. And it's a humbling realization that I think our species could use a lot more of.“ by Zoe Schlanger
- “If we decide this is all reflexive, then we all continue how the culture has always continued that just regards plants as quasi living, not particularly sentient, capable of interesting things, but ultimately closer to a rock than an animal, closer to a rock than, like, a whale or something. But if we decide that there's some element of subjectivity in a plant that starts to put them in a different category, I mean, it all is about how human culture responds to them.“ by Zoe Schlanger
- “You know, it has the effect of unseating us a little bit from this assumption that we're sitting sort of on the top of the evolutionary heap. Once you start to realize the incredible evolutionary fine tuning that goes into plants, it kind of shifts the ground beneath humanity to settle us a little more among other species.“ by Zoe Schlanger

Staff writer Zoë Schlanger is the proud owner of a petunia that glows in the dark. But she doesn’t just appreciate the novelty houseplant as work of science. Zoë sees its glow as a way to help us appreciate plants as more alive, more vital, and more complex than we humans typically do. Because in recent years, some scientists have reopened a provocative debate: Are plants intelligent?
They’ve devised experiments that break down elements of this big broad question: Can plants be said to hear? Sense touch? Communicate? Make decisions? Recognize kin?
Schlanger is the author of the upcoming book: The Light Eaters: How the Unseen World of Plant Intelligence Offers a New Understanding of Life in Earth. How could a thing without a brain be considered intelligent? Schlanger has spoken with dozens of botanists, from the most renegade to the most cautious, and she reports back on the state of the revolution in thinking.
