Summary:
- Researchers have analyzed a 324-million-year-old fossil of *Sierrachelys*, a primitive millipede-like creature, providing new insights into the early evolutionary transition of arthropods from aquatic environments to land.
- The study reveals that these ancient myriapods possessed specialized leg structures and respiratory systems that suggest they were among the first pioneers to successfully navigate and colonize terrestrial ecosystems during the Carboniferous period.
