Theory Briefing
- A new fossil discovery challenges the 150-year-old assumption that early land vertebrates evolved a tadpole phase like modern frogs.
- Paleontologists had long used modern frog development as a template for ancient vertebrate evolution — this find breaks that analogy.
- The discovery is a live example of Kuhnian paradigm shift: one specimen overturning a foundational scientific consensus.
