Adam Rogers poses some interesting questions about how we understand intelligence, but the observations he describes about slime molds pose an array of other questions. For instance, although a slim mold doesn’t possess a brain as a distinct organ, what might this organism’s aptitude in network formation tell us about the way neural networks are formed? Is it possible that these molds don’t so much lack a brain but rather that they are more like a brain with no body? (And forgive this off of the top of my head speculation. I know nothing about slime molds and not much more about brains.)
