UnverifiedCombining statistical modeling to provide extinction probability estimates for species that have not been sighted for a long time can trigger conservation or investigation mechanisms earlier72% similarUnverifiedVan Valen analyzed fossil records and found that the probability of a species going extinct does not decrease as its duration increases.72% similarUnverifiedThe smaller the population of a species, the lower the probability of it being observed, creating a statistical trap where the lack of sighting records makes it difficult to distinguish between extinction and simply being hard to detect65% similarUnverifiedThe feasibility of de-extinction technology is rapidly approaching, but societal, legal, and ethical preparedness lags far behind.64% similarUnverifiedWhen negative evidence accumulates to a sufficient spatiotemporal density, statistical models can support extinction determination with relatively high confidence in far less than 36 years62% similar
