Swiss pre-history
  • Archeology shows that Stone Age hunters have been
    living in Switzerland already before the last Ice
    Age (approximately 350'000 B.C.).
  • The majority of Switzerland's "native population
    settled during the Germanic Migration of Nations
    that set an end to the Roman Empire in Western
    Europe at about 400 A.D.
  • Switzerland's official latin name "Confoederatio
    Helvetica" goes back to a Celtic tribe called the
    Helvetians They belonged to a family of nations
    that has been designated as Indo-Europeans
    because of evidently common roots in their
    languages that distinguish them from Asian,
    African or Semite (Arab, Hebrew) languages. Among
    the Indo-Europeans we find the Greeks, the
    Romans, Germanic and Slawonian tribes but as well
    parts of the Persian and Indian population. It
    has been assumed that the Indo-European tribes
    all came from the prairies of Southern Russia.

Switzerland has written historic records from he
celtic Helvetians who spoke a celtic language and
the Rhetians who where not Romans but have
adopted the Roman language (Latin) before they
left any written traces. While the Rhetians,
living in the alpine valleys of southeastern
Switzerland, were able to preserve their language
(Rumantsch) and culture to our days, the original
celtic population has left almost no traces in
Switzerland except from a few geographical names.

Genetic markers on the Y chromosome
Markers used on Y chromosome are Short tandem
repeats or STRs, which are usually located
between genes and have no known physiological
effect
