Book excerpt: This tale of two deep springs in Florida that began as sinkholes about 13,000 years ago and the story of the precious water they contained, reveals the recent and prehistoric story of what is now the Sunshine State and the importance of its natural resources to its people. The mineral-charged spring water sustained Florida's earliest human populations--roaming hunter-gatherers who discovered the springs about 10,000 years ago and revisited them for thousands of years--in dry times and preserved their bones and artifacts for thousands of years. These dramatic tales based on the history of Florida's first people offer new perspectives on Florida's long history. The second time-period is recent and factual. Often outrageously stranger than fiction, it follows recent events int he history of the springs - the remarkable people who dived in the deep water-filled holes and put together the picture of human life-ways 10,000 years ago at the end of the Pleistocene Era. DNA analysis by world renown Svante Paabo revealed that these first Floridians were unrelated to the Native Americans living in North America today
