History of Florida - Early History

Early History

Florida used to be Orange Island, a low-relief island sitting atop the carbonate Florida Platform. The first land animals entered Florida approximately 24.8 million years ago.

When glaciation locked up the world's water, starting 2.58 million years ago, the sea level dropped precipitously. It may have been 100 metres (330 ft) lower than present levels. As a result, the Florida peninsula not only emerged, but had a land area about twice what it is today. Florida also had a drier and cooler climate than in more recent times. There were few flowing rivers or wetlands.

Paleo-Indians entered what is now Florida at least 14,000 years ago. Across large areas of Florida, fresh water was available only in sinkholes and limestone catchment basins. As a result, most paleo-Indian activity was around the watering holes. Sinkholes and basins in the beds of modern rivers (such as the Page-Ladson prehistory site in the Aucilla River) have yielded a rich trove of paleo-Indian artifacts, including Clovis points.

Excavations at an ancient stone quarry (the Container Corporation of America site in Marion County) yielded "crude stone implements" showing signs of extensive wear from deposits below those holding Paleo-Indian artifacts. Thermoluminescence dating and weathering analysis independently gave dates of 26,000 to 28,000 years ago for the creation of the artifacts. The findings are controversial, and funding has not been available for follow-up studies.

As the glaciers began retreating about 8000 BC, the climate of Florida became warmer and wetter. As the glaciers melted, the sea level rose, shrinking the land mass. Many prehistoric habitation sites along the old coastline were slowly submerged, making artifacts from early coastal cultures difficult to find. The paleo-Indian culture was replaced by, or evolved into, the Early Archaic culture. With an increase in population and more water available, the people occupied many more locations, as evidenced by numerous artifacts. Archaeologists have learned much about the Early Archaic people of Florida from the discoveries made at Windover Pond. The Early Archaic period evolved into the Middle Archaic period around 5000 BC. People started living in villages near wetlands and favored sites that were likely occupied for multiple generations.

The Late Archaic period started about 3000 BC, when Florida's climate had reached current conditions and the sea had risen close to its present level. People commonly occupied both fresh and saltwater wetlands. Large shell middens accumulated during this period. Many people lived in large villages with purpose-built earthwork mounds, such as at Horr's Island, which had the largest permanently occupied community in the Archaic period in the southeastern United States. It also has the oldest burial mound in the East, dating to about 1450 BC. People began creating fired pottery in Florida by 2000 BC. By about 500 BC, the Archaic culture, which had been fairly uniform across Florida, began to fragment into regional cultures.

The post-Archaic cultures of eastern and southern Florida developed in relative isolation. It is likely that the peoples living in those areas at the time of first European contact were direct descendants of the inhabitants of the areas in late Archaic times. The cultures of the Florida panhandle and the north and central Gulf coast of the Florida peninsula were strongly influenced by the Mississippian culture, producing two local variants known as the Pensacola culture and the Fort Walton culture. Continuity in cultural history suggests that the peoples of those areas were also descended from the inhabitants of the Archaic period. In the panhandle and the northern part of the peninsula, people adopted cultivation of maize. Its cultivation was restricted or absent among the tribes who lived south of the Timucuan-speaking people (i.e., south of a line approximately from present-day Daytona Beach, Florida to a point on or north of Tampa Bay.) Peoples in southern Florida depended on the rich estuarine environment and developed a highly complex society without agriculture.
