Do plants feel pain? | The Economist
- Scientists predict that some plant species may possess intelligence or consciousness, enabling problem-solving and environmental responses without neurons.
- Researchers plan to investigate whether plants can detect water sounds in pipes to guide root growth and utilize a potential echolocation mechanism similar to bats to sense supports before contact.
- Vines are expected to change leaf forms to mimic their host structures, while bean plants may emit and reflect sounds to calculate distances to support poles.
- It is hypothesized that plants possess a body intelligence allowing reactions to unforeseen changes beyond pre-programmed DNA, alongside bioelectric fields that store information for up to 28 days, as demonstrated by Mimosa pudica.
- Studies aim to confirm that neuronal behavior exists across all cell types and to determine if information processing is a fundamental biological process in non-neural systems.
- Expert predictions diverge on pain; one argues plants feel pain requiring dietary changes, while others contend pain is maladaptive for non-mobile organisms and that seed consumption strategies indicate plants "want" to be eaten.
- Grasses are expected to continue co-evolving with ruminants by relying on regeneration through grazing, whereas some scientists dispute the application of consciousness concepts due to a lack of interiority or self-awareness.
- The biological reality of plant suffering is disputed, with suggestions that interpretations of scents like jasmine as screams of abuse remain metaphorical rather than factual.
