The 8,800-Year-Old Man Found 1,000 Feet Inside A Colorado Cave — And The DNA Test That Linked Him To A Native American Founder Lineage
The Hourglass Cave bones were, by the standards of preservation needed for ancient DNA recovery, reasonably promising material.
Cold, dry conditions in caves — which reduce bacterial activity and slow the chemical degradation of DNA — can preserve genetic material for substantial periods.
The constant cold temperature of Hourglass Cave, maintained year-round by the cave’s thermal mass, was favorable for DNA preservation.
Whether enough genetic material had survived approximately 8,800 years in the cave to yield reliable results was a question that only laboratory work could answer.
