The comparison suggested the bones were more consistent with a female individual than a male.

Then, in 2006, Johnson reversed the sex determination again.

Further analysis by physical anthropologist Patricia Lambert, using femoral measurements compared to a reference collection from Tecolote Point — another Santa Rosa Island site — produced results that Lambert described as suggesting the individual was more likely male than female.

Lambert specifically acknowledged that the results were not definitive, but the balance of the femoral metric evidence leaned toward male.

The reason for the uncertainty is intrinsic to the evidence.
