Gaomiao Culture and Chinese Characters

[SVanTha]

I recently found out about an archeological site called "高庙文化" ("Gaomiao Culture").  It's located in Hunan province, near the city of Hongjiang (洪江市) and is associated with the surrounding ancient cultures, which have ties to hmong/miao people:  http://baike.baidu.com/view/2506365.htm

It's interesting for its religious finds and its pottery.  Scholars think it was a regional religious center and that it may contain the earliest evidence of logographs (characters for words).  The site has been dated to about 7,000-7,500 years old.  Here's what one scholar writes about it:  http://www.wenku1.com/news/495AE594C1AD70A6.html

[出人意料的是，据贺刚介绍在高庙上层文化和高庙文化中都发现一些神秘符号。笔者在观摩高庙遗址出土距今7000—7500年的一些陶片上发现有“火”、“⊙”、“井”、“圭”、“▽”等符号，其中“⊙”与甲骨文的“日”字一模一样。]  He notes that there are symbols similar to other logographs and points out that the “⊙” symbols are exactly the same as the ones on the oracle bones to denote "day" or "sun".

It's interesting that ancient logographs are consistently found in relation to religion.  So the genesis of chinese characters likely disseminated by hmong/miao ancestors through their religious practices?
