520-Million-Year-Old Arthropod May Have Had the First Modern Brain 60

Posted by samzenpus from the wile-away-the-hours dept.
An anonymous reader writes "Scientists say that the recently discovered 520 million year old insect brain, the oldest brain ever discovered in an arthropod, is surprisingly complex for its age, and may be the earliest example on record of a modern brain structure. Hailed as a 'transformative discovery,' researchers said that the 3-inch-long fossilized extinct arthropod found in Yunnan Province, China, shows that insects evolved to have complex brains significantly earlier than previously thought. Researchers said that the fossilized brain, which looks very similar to brains of modern insects, may provide a missing link that offers new insight on the evolutionary history of arthropods, a group of invertebrates that includes insects, spiders and crustaceans."

        The feather (or pen) is mightier than the sword, so calculators (especially sharp ones) should be considered dangerous.
        On the other hand I'm have some trouble with the exact level of dangerousness. If pen beats sword (and thereby knife and dagger), what would a pocket calculator beat?

            Nice one... Still the question of what weapon a calculator would beat remains unanswered. A pointy stick, a knife, assault rifle, sarin gas or an icbm? The whole issue is rather tricky. In close combat a pocket calculator is rather worthless, even if thrown in a slingshot. If it is used to calculate ballistic flight paths for artillery things change...

      You didnt miss much. Just some conclusions about the evolution of insects:

      They explained that up until now, research on insects has been divided into two camps. While some researchers believe that insects evolved from the same ancestor that gave rise to malacostracans, a group of crustaceans that include crabs and shrimp, the majority of scientists believe that they were derived from a group of crustaceans called branchiopods, a species that includes include brine shrimp, which have a simpler brain anatomy than malacostracans.

      However, researchers from the latest study say that the new finding shows that insects did in fact evolve from creatures that already possessed complex brains.

          Heinlein also had certain political views that he trotted out in his books: citizenship through service, government control, propaganda, etc. The Starship Troopers movie actually does a really good job of a lot of that.

    520 million years, or a good ways into the Atdabanian Stage. At that point trilobites have been around for at least 6 million years already. Surely they had fairly sophisticated arthropod brains. I dunno, this seems a little late, the primary radiation in Euarthropoda almost certainly came before this guy lived. In any case the systematics of arthropods are a mess.
