The Genius of Pinheads: When Little Brains Rule

The world’s smallest arachnid, the Samoan moss spider, is at a third of a millimeter nearly invisible to the human eye. The largest spider in the world is the goliath birdeater tarantula, which weighs 5 ounces. and is about the size of a dinner plate. For reference, that is about the same difference in scale between that same tarantula and a bottlenose dolphin.

And yet the bigger spider does not act in more complex ways than its tiny counterpart. “Insects and spiders and the like—in terms of absolute size—have among the tiniest brains we’ve come across,” says William Wcislo, a scientist at the Smithsonian Tropical Research Institute in Panama City. “But their behavior, as far as we can see, is as sophisticated as things that have relatively large brains. So then there’s the question: How do they do that?”

The computers that put a man on the moon were the size of several large refrigerators. My first windows based computer was almost as large as a suitcase plus the monitor! My cell phone has more computing power than both of them together!! You can't compare hardware and software based on physical size whether it is electromagnetically or organically based. A primitive brain structure just can't compete with a more evolved one irregardless of size.
