== Indigenous peoples of the Americas == 

 I took up my reading of this article again, and I wanted to ask your opinion about something. In the last paragraph in the section "Pre-Columbian peoples" (or something like that), "Pre-Columbian" is in quotation marks when referring to the Norse who settled on the North Atlantic coast of what is today Canada.  I wonder whether the quotation marks are necessary.  That time really was Pre-Columbian by either definition outlined in the second paragraph of this section.  The quotation marks seem to minimize the presence of the Norse. What do you think?
