The Hourglass Cave sequence was described in these later analyses as representing a founder haplotype — a mitochondrial sequence closely related to the ancestral types from which contemporary haplogroup B lineages in Native American populations descend.

This characterization — founder haplotype within haplogroup B — is the most accurately stated version of the genetic finding.

It avoids overstatement (the sequence is not a complete genome, does not represent a specific tribal affiliation, and does not demonstrate direct descent to any specific living person or community) while capturing the genuine significance (the man carried a maternal lineage that is part of the deep founder diversity of all Native American peoples).
