Webthat DNA survived in non-coprolite specimens from the Paisley Caves for long times also. The results strongly suggest that leaching of DNA is not a concern in the Paisley Caves, and are in agreement with empirical and theoretical evidence suggesting that significant amounts of liquid water are required to move free DNA molecules between strata (17,
