Humans May Have Been in North America 50,000 Years Ago
    #3381267 - 11/18/04 09:17 PM (12 years, 23 days ago)

http://www.sciencedaily.com/releases/2004/11/041118104010.htm

I wasn't sure where to post this.

Basically, an archeological team recently found a suspected human site from approximately 50,000 years ago. This is big news, because there hasn't been a definite find older than 17,000 in North America. Especially on the East Coast. Most the sites older than 11,000 have been found out West because the moisture and acidity of eastern soil tends to erode artifacts.

The 50,000 number was carbon dated from charcoal in the soil. I'm a little suspect of this, because very old charcoal samples have been known to be contaminated or be from natural causes.

And I'm basically very skeptical of this whole thing. At 50,000 years ago, crossing the Bering bridge would have been extremely difficult. And ice would have been extended over most of what is now the northern US. People hypothesize that people traveled along the edge of the glacier in boats, crossing the northern Pacific. I'm not sure about this either, because weather on the edge of a glacier can be severe and not friendly on the boats primitive man used.

There's an idea I came up with last year. I'm not sure if anyone has offically proposed this. I guess someone probably has... But I wonder if people crossed over the south Pacific. There have been several finds on the western South American coast that are apparently over 30,000 years old. There's evidence of people inhabiting Polynesia close to 40,000 years ago. And in examining the genetics, dental patterns and languages of native americans, there are many asian influences, but there are also genes from New Guinea. It's also worth noting that the ancient people in New Zealand and Polynesia probably built the first sea worthy boats.

I think that maybe there was a small wave of people who migrated from the south Pacific. And then there was a massive wave of people from northern Asia around 13,000 years ago... But considering that I've never heard my idea seriously discussed, maybe it just doesn't make sense.

I just wish people used more accepted versions of dating then c14 carbon dating. Alot of people disregard discoverys if the key elements of fact are due to c14. We need a more widely excepted method.

Im going to make up an example of something.

A cave discovered in Mexico with artifacts. We find the only organic thing to be a spoon made out of camel bone. It has a mean age of of 835 ? 35 radiocarbon years BP. So thats about... around 3,500 years BC.

What does this tell us?
It tells us the camel died around 3,500 years BC.
