Archaeologist: After the last ice age, groups of paleohumans left Siberia and crossed the Bering land bridge, which no longer exists, into North America  Archaeologists have discovered in Siberia a cache of Clovis points -- the distinctive stone spear points made by paleohumans
This shows that, contrary to previous belief, the Clovis point was not invented in North America
The Clovis points found in Siberia are older than any of those that have been found in North America.
