In certain outlying parts of Scandinavia and Ireland, a primitive race - the Palaeo-Atlantid-still lives in small remnants (See Map 18). The Palaeo-Atlantid race is darker than the Nordid race - especially as regards to hair color. It is also coarser than the Faelish subrace, with stronger brow ridges, and a broader, plumper nose. With respect to the ABQ-blood group system, the Palaeo-Atlantid race is high in blood type gene r and low in blood type genes p and q. In the north, this race is named the Tydals race, after a village in central Norway.
Now we shall briefly outline the most important facts known to us of the still older history of the races of Europe. The present geographical distribution of these European races is shown in Map 17. The Palaeo-Atlantids are relatively unmixed and unaltered descendants of the Palaeolithic West European and North African Cro-Magnid race. The Cro-Magnids followed northwards the retreating ice boundary at the end of the Pleistocene. They lived as specialized hunters of the fauna inhabiting this part of Europe.
The Palaeo-Atlantids were never as depigmented as the Faelish and Scando-Nordid tribes who migrated after them. The latter two races have originated from other, later, closely-related Cro-Magnid proto-groups. The Faelids and Scando-Nordids were already at that time racially and culturally somewhat more highly developed. They gradually forced the Palaeo-Atlantids back into their present, barren places of refuge.
The origins of the races of Europe can be traced back to the end of the last Ice Age and the beginning of the succeeding Mesolithic period. The retreating ice cover opened up for settlement new areas of Europe. Changing climate, expanding area of settlement, and more varied habitat provided the selective forces for differentiating and molding the living races of Europe.
The descendants of the West European and North African Cro-Magnid race followed the retreating ice into western and northern Europe. The earliest migrants were the Palaeo-Atlantids, followed by the Faelish and Scando-Nordids. The depigmentation of the Faelish and Scando-Nordid races appears to have occurred as an adaptation to the cold and cloudy climate of northern Europe. The East Baltid race in adjacent areas of northeastern Europe also became strongly depigmented or blond. In the warmer and damper northwest of Europe, however, the Palaeo-Atlantid and North-Atlantid races became only partly depigmented. Thus, arose the contrast between the blond North and the brunet South of Europe which has existed for several millennia
