An excellent online history of lampreys and hagfish

Fossil Friday: Hagfish and Lampreys Overturn Scenarios of Vertebrate Phylogeny and Evolution

Here is an excellent history
of lamprey and hagfish evolution papers (Günter Bechly 2024) lacking only one key item: a last common ancestor. In the LRT a marine nematode, Enoplus, serves as the outgroup taxon. See link below for details.

Quick note:
This website appears to be devoted to a Creationist (intelligent Designer) ideal. So it emphasizes the arguments of paleontologists and focuses on conflicts between gene and trait studies. Even so, the writing and the citation list is impressive. Then again, they called professor Michael Benton, in their words: ‘the worlds foremost expert on the fossil record’.

Enter this ‘cave’ with curiosity.  Leave this ‘cave’ with data.
Figure things out for yourself by entering and leaving as many ‘caves’ as you can.
