What happened when Wegener proposed continental drift?
Yes - rivals diagnosed Alfred Wegener with 'moving-crust disease,' a Stanford geologist branded drift a 'fairy tale,' and a London audience cheered that his theory had been 'blown to bits.' But the textbook reason he was rejected - that he 'had no mechanism' - is, according to the historian who actually read the archives, false.

Did Arthur Holmes 'solve' the mechanism with mantle convection in 1928? Not in his lifetime's debate▰▰▰▱▱ likely1 against4 points
Supports- Did Arthur Holmes 'solve' the mechanism with mantle convection in 1928? Not in his lifetime's debateArthur Holmes (Geological Society of Glasgow) summary
- In a 1928 lecture (published 1931) Holmes proposed slow-moving thermal convection cells in the mantle as a physical mechanism that could carry continents apart like a conveyor belt.Arthur Holmes (Geological Society of Glasgow) summary
- Oreskes: Holmes argued radiogenic heat drives convection - ridges as upwelling where continents split, ocean deeps as downwelling - dragging continents along; his papers were widely read.Naomi Oreskes, 'Continental Drift' (essay, UC San Diego) analysis
Against- Yet the idea 'received very little attention at the time' and was not taken up until the 1960s - lacking confirming data, it did not win acceptance during Holmes's prime.Plate tectonics: history of an idea - UCMP Berkeley summary

- Explainers routinely state the primary reason for rejection was Wegener's inability to propose a plausible physical mechanism capable of moving continents.Why Was Wegener's Theory of Continental Drift Rejected? (ScienceInsights) summary
Against- Oreskes flatly states: 'The standard explanation for the rejection of continental drift is the lack of a causal mechanism, but this explanation is false. There was a spirited and rigorous international debate' over mechanisms.Naomi Oreskes, 'Continental Drift' (essay, UC San Diego) analysis
- She argues the real obstacles were prior intellectual commitments - to Pratt isostasy, the 'method of multiple working hypotheses,' and uniformitarianism - not a missing force.The Rejection of Continental Drift (Oreskes, Oxford University Press) analysis
