A Type II survivorship pattern only shows that extinction probability is independent of taxon age in the analysed data. In Type II survivorship, survival probability is constant at e^(-lambda) and does not depend on time. The intervals between extinction events can be represented as a Poisson point process when events occur independently at a constant average rate. Memoryless extinction does not imply ecological and environmental factors are irrelevant to which species go extinct.
