Luzia, died at the age of 24, 11,500 years ago in Brazil. (she is the oldest dated skeleton ever found in the Americas)
Luzia, is closer in time and geography to the area mentioned in this article than any other to date. (There is a skeleton found on an island off the coast of California that some believe will be older than Luzia, but not yet.)
The Monte Verde site, 35,000-50,000yo will (probably) cause havoc (eventually) with all that we know about this area.
Where is that ?
