Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Geckos maintain their remarkable foot adhesion on dusty surfaces because their specialized setae and spatulae incorporate self-cleaning mechanisms that shed dirt during locomotion.

The analysis

Multiple retrieved papers (0, 2, 5, 6) explicitly study and confirm that gecko foot structures (setae and spatulae) have self-cleaning properties that prevent dust and debris from permanently interfering with their adhesion. There is no evidence in the provided papers refuting this claim.

Evidence for self-cleaning in gecko setae

Recorded source metadata

W. R. Hansen, K. Autumn. Evidence for self-cleaning in gecko setae. 2005. https://doi.org/10.1073/pnas.0408304102

Demonstrates that gecko setae possess intrinsic self-cleaning adhesive properties that allow geckos with dirty feet to recover their clinging ability.
