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

Studies on conifer cambium development confirm that changes in fusiform cambial cell orientation and division patterns drive the formation of spiral tree growth.

The analysis

The provided papers detail the specific cellular mechanisms within the vascular cambium—such as anticlinal divisions and microdomain shifts—that lead to spiral grain formation, thus supporting the claim.
