#28, RedCream = geophysical realist. The Indo-Europeans had the singular geographic advantage that quite simply allowed successful spreading ALONG LATITUDES. Their land routes were workable and their crops were largely successful in new lands. In addition, the lack of tropical vegetation and climate gave them food storage and variety not possible in most of Africa.
Now STFU. You're just a demented idiot who likes to needlessly politicize a purely geographic argument.
