The settlers in the first wave, who walked across the Bering Land Bridge 15,000 years ago, were the forebears of present-day inhabitants south of the U.S.-Canadian border

Does this say that Mexicans of Indian ancestry aren't Indians but from a variety of other Asian groups?

Back up. According to statistical geneology, everyone living today is probably a decendent of every person living just 1,500 years ago (except for those people living 1,500 years ago who have no decendents today living). Have people live apart from others for a few hundred years, and the separated groups will soon having distinctive language, appearance, etc. Appearance will be related to predominent genetic backgrounds. But to say that today's this or that group of people is descended from some group living thousands of years ago is way overstated.

Indians, of the North American kind, are Asians that moved at some time to North America. Mexicans have no excuse to do poorly in mathematics.
