“…These strategies are based on the community and require a minimal critical mass, which is sensed through pheromones (Golden & Riddle, 1984). While all animals undergo transcriptional changes to respond to the pathogens (Gabaldon et al, 2019), only a fraction of the population is committed to diapause with a constant number throughout the generations and experimental interventions. Even dead individuals are perceived as "community" members, likely because the pheromones can still be sensed by others (Gabaldon & Calixto, 2019).…”

Even dead individuals are perceived as "community" members, likely because the pheromones can still be sensed by others (Gabaldon & Calixto, 2019). Birch et al (2020) suggest that the evolution of mechanisms restricting the transgenerational transmission of the effects of stress to the next generation took place after the Cambrian explosion, and thus, transgenerational transmission of the effects of stress are more likely in animals without UAL than in animals showing UAL.…”

While subcellular components of cognition and affectivity that involve the interaction between experience, environment, and physiology —such as learning, trauma, or emotion— are being identified, the physical mechanisms of phenomenal consciousness remain more elusive. We are interested in exploring whether ancient, simpler organisms such as nematodes have minimal consciousness. Is there something that feels like to be a worm? Or are worms blind machines? ‘Simpler’ models allow us to simultaneouslyextract data from multiple levels such as slow and fast neural dynamics, structural connectivity, molecular dynamics, behavior, decision making, etc.,and thus, to test predictions of the current frameworks in dispute. In the present critical review, we summarize the current models of consciousness in order to reassess in light of the new evidence whether Caenorhabditiselegans, a nematode with a nervous system composed of 302 neurons, has minimal consciousness. We also suggest empirical paths to further advance consciousness research using C. elegans.
