There are many traces of the ancient human race in the territory of
Mongolia, including archaeological discoveries in the white cave of
Bayanlig and stone weapons found in the Uran Khairkhan hill of
Baatsagaan somon, Bayankhongor aimag. According to the discoveries,
it becomes likely that human being lived in the territory of Mongolia
almost 700 thousand years ago. There is a hypothesis that Mongolia
is the cradle of the very first human race on Earth. This assumption
is based on the appearances of Mongols. Mongols had straight black
hair, broad foreheads, narrow eyes, thick lashes, short noses,
protruding cheek bones, strong chests and narrow waists. Those people
were the product of nature and climatic conditions of Mongolia. Skilled
labor produced the homo sapiens almost 40,000 years ago. With the
increase of wealth and emergence of private ownership, the clan
structure collapsed. Wealthy families came to live in aimag structures.
Several aimags formed a union of aimags. Power was concentrated among
few descendants of wealthy families and heads of aimags.
