Next Time You Bait A Hook With a Worm…

Consider this.

This study suggests that our earlier ancestors, pre fish I assume, may have been from the worm family. So many relevant details in the article, I’d have to darn near copy/paste them all. More efficient to just click the link, I think. If you are inclined that is.

There is a video there, but if there was a narration it was not present for me.

In a nutshell:

  • Notochord (1st vertebrate skeleton) probably evolved from muscle
  • Evolutionary origin of notochord likely older than assumed
  • Marine worm has muscle with same genetic signature, in same place
