Madison Grant,
The Conquest of a Continent; or…
“ Eurasia, where it is probable that mankind originated, was the greatest land mass on the globe in Tertiary times. Modern Europe and North Africa formed relatively small peninsulas in the extreme west of this Tertiary land mass. It is probably from Eurasia that man spread out to the uttermost parts of the habitable globe, carrying with him his language and such cultural features as had developed at the time of each successive migration. No race or language or cultural invention seems to have entered Eurasia [Pg 19] from adjoining land areas. ”
