One modern date related to an intrusion," Stafford says."The two 50,000 dates indicate that they are at least 50,300 years.Radiocarbon tests of carbonized plant remains where artifacts were unearthed last May along the Savannah River in Allendale County by University of South Carolina archaeologist Dr.Albert Goodyear indicate that the sediments containing these artifacts are at least 50,000 years old, meaning that humans inhabited North American long before the last ice age.OSL (optically stimulated luminescence) dates on soils above ice age strata show pre-Clovis is at least older than 14,000.May 2002 — Geologists find new profile showing ancient soil lying between Clovis and pre-Clovis, confirming the age of ice age soils between 16,000 - 20,000 years.
"Fifty-thousand should be a minimum age since there may be little detectable activity left." The dawn of modern homo sapiens occurred in Africa between 60,000 and 80,000 years ago.May 2000 — Geology study done by consultants; ice age soil confirmed for pre-Clovis artifacts.May 2001 — Geologists revisit Topper and obtain ancient plant remains deep down in the Pleistocene terrace.Evidence of modern man's migration out of the African continent has been documented in Australia and Central Asia at 50,000 years and in Europe at 40,000 years.The fact that humans could have been in North America at or near the same time is expected to spark debate among archaeologists worldwide, raising new questions on the origin and migration of the human species.
