resurrected · Unscored / disputed
Continents had once been joined and subsequently moved apart, making measurable horizontal motion a testable consequence.

Alfred Wegener
Meteorologist and geophysicist · Germany
The world at the time.
Matching fossils, geological structures and continental outlines motivated Wegener’s drift theory. It was rejected by many geophysicists because its driving mechanism was inadequate.
What happened.
Ocean-floor evidence and plate tectonics established the mobility of continents during the 1960s. The continents move as components of plates, rather than ploughing independently through oceanic crust as Wegener proposed.
Predicted vs actual.
| Metric | Predicted | Actual | Variance / caveat |
|---|---|---|---|
| Continental mobility | Continents drift | Plate motion established | Core claim confirmed; mechanism changed |
The counter-signal.
The theory’s weak account of driving forces was a substantive objection, not merely resistance to an outsider. Jeffreys later formalized the difficulty of continental rock ploughing through the ocean floor.
Verdict.
Reasoning: contested · Outcome: partial
The core mobility claim returned from rejection, but its original mechanism did not survive. A partial verdict preserves the distinction between an insightful historical reconstruction and a fully correct physical theory.
Cause of death / explanatory lens.
No cause of death assigned
The lesson.
Can the observed pattern be right while the mechanism explaining it is wrong?
