Primes

• Uniformitarianism
  • Modern geology and evolutionary biology treat uniformitarianism and catastrophism as complementary: background uniformitarian processes interspersed with catastrophic episodes (mass extinctions, megafloods, bolide impacts), as Alvarez et al. (1980) demonstrated for the K-Pg boundary impact event.

    This sourceDocuments the iridium anomaly at the K-T (now K-Pg) boundary and proposes a bolide impact as the cause of the end-Cretaceous mass extinction; landmark example of catastrophic discontinuity admitted alongside uniformitarian background processes.
