Even Simple Creatures Can Learn, Challenging Ideas About Learning and Intelligence

Scientists have discovered that even brainless jellyfish can learn through trial and error.
The findings show that even simple creatures without brains can exhibit learning abilities.
This challenges conventional thinking that sophisticated neurobiology is needed for learning.
Researchers taught jellyfish to navigate around obstacles, showing they can modify behavior based on experience.
The results suggest the capacity for learning may be fundamental to all nervous systems, not just advanced brains.
