Fossil constraints on the origin and evolution of Platyhelminthes are surprisingly concordant with modern molecular phylogenies [PDF]

open access: yesZoologia (Curitiba)
Trace fossils preserved with fossil worm-shaped remains suggest the presence of free-living flatworms during the Ordovician at the latest and their occurrence in terrestrial environments during the Permian.

Substrate for Thyroid Hormone Synthesis: Biochemistry, Evolution, and Physiology

open access: yesThe FASEB Journal, Volume 40, Issue 8, 30 April 2026.
Two proposed sequence of events for thyroxine formation in patients expressing mutant thyroglobulin. (A) (1) TSH stimulation drives expression of misfolded TG. (2) Unremitting ER stress. (3) Stress‐induced cell death. (4) Dead thyrocytes release their contents. (5) The contents become iodinated. (6) Forming thyroxine.
