The result is a form of preservation by deprivation.

The organic material in peat is not preserved because some active preservative protects it; it is preserved because the conditions that would normally destroy it are absent.

At Windover, there was an additional factor.

Multiple sources, including the Orange County Regional History Center’s account of the site, note that the Windover pond appears to have had a nearly neutral pH — unusual for a peat pond in Florida, where most peat deposits are significantly acidic.

This near-neutral chemistry may have been particularly important for the preservation of biological molecules like DNA, which is rapidly degraded in very acidic conditions.
