Common questions
How does MNE differ from MNI in a commingled remains case?+
MNE counts complete elements of one type, for example how many distinct left femurs are represented by all the femur fragments recovered, while MNI counts individuals inferred from the whole assemblage. MNE is a building block used alongside other elements to estimate MNI, not a substitute for it.
Why does MNE matter for DNA sampling strategy in mass fatality cases?+
Knowing how many distinct elements of a given type are present helps prioritise which fragments to sample so DNA testing captures the maximum number of separate individuals without wastefully re-testing pieces from the same element, which matters when sample budgets are limited.
Can MNE be calculated from fragments alone, without any complete bones?+
Yes. Analysts use overlapping anatomical landmarks, size, and side, left versus right, across fragments to determine the minimum number of separate elements needed to account for all the pieces, even if no single fragment is a whole bone.
