In 2007, Bill Napier published a paper questioning why so little effort had been made to connect known crater fields with periods of enhanced cosmic activity. That same year, Firestone, Kennett, and West published their landmark paper proposing an extraterrestrial impact at the Younger Dryas boundary. The timing is striking. Napier was asking why the scientific community wasn't looking for these connections, while simultaneously, evidence for exactly such an event was being presented. It raises questions about how research priorities get set and why certain lines of inquiry remain unexplored until someone forces the issue. The convergence of these two papers in the same year suggests the field was on the cusp of a major shift in thinking about cosmic impacts and their role in Earth's recent history.
