I replied to half a dozen comments of people freaking out about the genetics showing "Australoid phenotype" for people living in Europe 27,000 years ago - call them Cro-Magnons or Gravettians - they were from Africa like Australian aborigines or Melanasians or early native Americans. We're all originally African with African-traits.

This ancestry profile survived during the Last Glacial Maximum (25,000 to 19,000 years ago) in human populations from southwestern Europe associated with the Solutrean culture, and with the following Magdalenian culture that re-expanded northeastward after the Last Glacial Maximum. Conversely, we reveal a genetic turnover in southern Europe suggesting a local replacement of human groups around the time of the Last Glacial Maximum, accompanied by a north-to-south dispersal of populations associated with the Epigravettian culture.
This genetic signature is shared among individuals associated with the archaeologically defined Gravettian culture (33–26 ka) in central and southern Europe and seemingly disappeared after the Last Glacial Maximum4 (LGM). However, the genetic profile of contemporaneous Gravettian-associated individuals from western Europe remains unknown, as is their contribution to populations after the LGM. Known to have been the coldest phase of the last Ice Age, the LGM is considered to have caused a demographic decline in large parts of Europe10, with populations retracting to southern latitudes as attested—for example—by the contemporaneity of the Solutrean culture (24–19 ka) in the Iberian peninsula and southern France. Other proposed climatic refugia for human survival during this period are the Italian peninsula, the Balkans and the southeastern European Plain, but the actual genetic contribution of populations from these regions to post-LGM Europeans is highly debated11,12,13.
western and eastern European hunter-gatherers, who were also characterized by marked differences in phenotypically relevant variants.
Consistent with previous findings, none of the analysed groups show the derived allele at SNP rs4988235 on the LCT gene, which is responsible for lactase persistence. As previously hinted37, we find a large frequency variation in alleles related to skin and eye pigmentation among post-LGM hunter-gatherer groups. For the SNP associated with light eye colour (HERC2/OCA2 (rs12913832)), individuals from the Villabruna cluster, Oberkassel cluster, Baltic HG and SHG groups show high frequencies of the derived allele (>90%), which is responsible for the green or blue eye phenotype, whereas Sidelkino cluster, Ukraine HG and Iron Gates HG groups show low occurrence of this allele (10–25%).
Wow so my green hazel eyes are from probably Baltic area genetics? cool. I'm from Dresden area on my dad's said going back to my great-great grandfather maybe? My great-grandfather apprenticed in Sweden at a carpentry factory - I have it written down that either his dad or the dad before came from Dresden area after Napoleon had invaded. 1813.... So he lived probably till 1860s. So that would mean his son traveled to Minnesota...to make my grandfather...
On the basis of the genetic variation of present-day Europeans, this could imply phenotypic differences between post-14 ka hunter-gatherer populations across Europe, with individuals in the Oberkassel cluster [Central Europe] possibly exhibiting darker skin and lighter eyes, and individuals in the Sidelkino cluster possibly lighter skin and darker eye colour [Southwestern Europe].
fascinating.
