Note 120 — Chapter XVII
Reading edition
A. Reibmayer (Inzucht u. Vermischung beim Menschen, Leipzig, 1897) insists upon the importance of isolation and consequent inbreeding for the formation of superior strains and subraces. He points out that the geographical barriers of Europe have favoured in this way the production of distinctive national types. Like Stewart Chamberlain, Flinders Petrie, and others, he regards the dark ages of Europe as a period of chaos directly due to the overcoming of these geographical barriers and the consequent prevalence of crossbreeding on a large scale.
