“Spiders are very smart, that’s why we’re studying them,” says Ronald Hoy, a professor of neurobiology and behavior at Cornell University. “They use visual cues to steer by, and the kind of mazes that they can solve is considered to be pretty impressive for an invertebrate.”
There is a limit to how small neurons can get, so
Perhaps as a solution to space limits, some small spiders have brains that spill out all the way into their legs. Scientists have discovered that the central nervous systems of the smallest spiders fill up almost 80 percent of their total body cavity, including about a quarter of the space inside their legs. More.
It was easier to believe in Darwinism when we thought spiders had no brains.
