- interesting article looking at the origin of modern European DNA profile
- the idea that the earlier hunter-gatherer population was replaced by a wave of migrants from the Middle East at the beginning of the Neolithic period
- a new idea that a major shift in population also occurred around 4500 years ago that needs to be explored more
- the "Bell Beaker" culture group seems to have played an important role in this late shift (curiously, they are strongly related genetically to the populations in modern Spain and Portugal)
