Thanks. Checked it, looks good. Funny thing, comments on Amazon disclose that the same book was also reissued under the title “1493”....
A 1491 Timeline:
25000-35000 B.C. Time of paleo-Indian migration to Americas from Siberia, according to genetic evidence. Groups likely traveled across the Pacific in boats.
