    This is not strictly ceph-related, but I think it touches on one of the reasons people like to study cephs: studying cephs because they evolved interesting behaviors independently of vertebrates is good as a "compare and contrast," while studying worm-like things that aren't worms is nifty for similar reasons, because ultimately, we're all worms at heart.

    researching that also led me to some other bits that I found interesting: HOX genes in cnidarians may not show as much close relationship as we thought:

    but sea anemones and humans share more in common than one might expect:

    If this is too non-ceph, I can shift it to supporters, but I suspect it might lead to some interesting on-topic-ish discussion...
