I have a theory. It is based on the Moa bird of New Zealand, and relates to Sweden.
New Zealand was an island that stood in a near frozen state (from the stand point of evolution) for nearly 90 million years. During this time many animals evolved to their surroundings and the threats they faced. The Moa had one predator, Haast's eagle, the largest eagle ever discovered. For millions of years there was a predator/prey scenario that played out.
With the arrival of the Maori people, probably from Samoa or Tonga. The Moa bird faced a new predator and within a few hundred years it was hunted to extinction. With it's dwindling population the great Haast's eagle also went extinct.
Thus, Sweden being an island nation has virtually gone untouched for centuries. A homogeneous culture developed which has become the modern day Swede.
They have been in stasis for hundres of years. Now with the introduction of foreigners who possess not spears and claws but a virulent ideology, lower IQ and violent tendencies we see how, for the most part a DOCILE island species is reacting to the introduction of a new predator into its ecosystem...
My conclusion, Sweden as we know it will go extinct.
Now some of you may think this is obvious, however, I am explaining the reasoning why from the point of view of evolutionary biology/psychology.
The intelligent Swede has become pacified and domesticated. While their ancestors were feared for their raids and violent nature they have become a tame version of their former selves living in isolation from new predators.
>Simply a thought experiment. I was wondering my fellow /pollacks take on this point of view.
