Early catastrophists like Buckland & Cuvier saw evidence of processes unlike those occurring today. By the mid-1800s, Lyell's gradualism dominated — calling past processes 'unscientific.' Modern geology recognizes elements of both perspectives. 🌊⚡
Key facts confirmed:
- Uniformitarianism tagline: 'the present is the key to the past'
- Early geologists (Buckland, Cuvier, Sedgwick, Murchison, Humboldt) were catastrophists
- They saw evidence of processes unlike those occurring today
- Post-Civil War, Lyellian gradualism became dominant in academic geology
- Geologists rejected invoking processes not observable today as 'unscientific'
- Contemporary geology incorporates catastrophic events (e.g., asteroid impacts, flood basalts) alongside gradual processes
