Who were the first Europeans?

A May 19, 2005 article by Science Editor Roger Highfield at the UK Telegraph News reports in Bones show age of early settlement that ancient bones from a half-dozen humans found in the Czech Republic "have been confirmed as representing the earliest settlement of modern humans in Europe", dating to around 30000 years ago by radiocarbon analysis. This is rivaled only by one similarly dated (said to be ca. 35000 years ago) jaw bone and cranium from Romania.

This dating is extremely significant for an understanding of the ancient history of Europe and the Europeans, especially in view of the following graph by Kelus & Lukaszewicz as found in Ludwig Hirschfeld (Ludwig Hirsfeld, Ludwik Hirszfeld), Probleme der Blutgruppenforschung, Fischer Verlag, showing the Czechs near the center of the branching of human blood types in Europe:
for the graph see LexiLine, Blood Types Worldwide.

We thus have a direct match of the distribution of blood types in Europe with the date of the radiocarbon analysis of human bones in the Czech Republic, thus substantiating the hypothesis that the origin of all European peoples is in the East European area.
