The article’s most intriguing implication is that Ireland’s apparent archaeological silence may reflect both intermittent human access and the destructive effects of later glaciation, rather than an uninhabited island. Derryvree’s wetland interval and Castlepook’s fauna together suggest opportunities, yet neither can establish sustained occupation. The possibly modified reindeer bone sharpens this tension: it may indicate a visit, but not a community or cultural tradition. How should researchers weigh environmental evidence, cave assemblages and taphonomic loss when assessing whether mobile hunter-gatherers could have used Ireland during Marine Isotope Stage 3, and what discoveries would persuasively distinguish occasional visits from repeated occupation?
