Pretty interesting stuff.
Especially the diet.
Salt water closer via st lawerence system area
Than over continent to pacific.
Read alot about a possible meteor strike on glacier shelf north of great lakes region 13 to 15000 yrs ago caused the st lawerence system, Mississippi sytem and great lakes to form.
Also affected climate with massive dump of cold water into the alantic.
Which also is theorized why their is a 5 to 7 ft layer of silt in the artifact layers of about 4k years in the mid alantic coast area from the dump of cold water in the alantic and making those areas inhabitable.
Which also drove early man into the middle of the continent over the Appalachians.
All theory tied together in ways.
But still interesting reading just google fu,ing stuff.
