We’ve known this for quite some time already. Many animals without a centralized brain have neuron ganglia distributed across the body that coordinate central functions.
Entirely unrelated but I stepped on one this summer and gained a whole new level of respect for the little bastards.
As deuterostomes (organisms whose assholes develop first, as opposed to protostomes, whose mouths develop first) urchins have more in common genetically with every vertebrate than every invertebrate.
