A team of researchers from Korea, the U.K. and Denmark has found fossilized brains of sea creatures that lived during the Cambrian explosion. In their paper published in the journal Nature Communications, the group describes features of the brains and why they believe their findings may overturn a commonly held belief about the ancestry of panarthropods and invertebrate panarthropods and also vertebrates.
