Hey, wwh. Something's wrong with that last article. Read this:

"In North America the atlatl can be traced back in the archeological
record some 8 to 10 thousand years, whereas the bow has been generally
accepted as being introduced only 1500 to 2000 years ago."

The article was written in 1997. Two thousand years before 1997 would be 1797.

Certainly the natives the English encountered here in Virginia at from 1607 on--just to mention our English colonization--had bows and arrows. Didn't they?

So the 2000 year fact in the article appears to be completely incorrect by at least two hundred years.
