text: Yo, check it out, we got a fresh database flowin'
  Ethnohistorical records, Europe's history we're knowin'
  3460 entries, holdin' ethnic locations and their moves
  From 2200 B.C., we got the groove
  
  Using this data, we crunchin' them numbers
  Calculatin' vectors, proportions, no slumbers
  Language families speakin', genes they contribute
  To the land-based quadrats, yo, we compute
  
  2216 quadrats, each one a degree by degree
  Ethnohistorical distances, that's what we see
  Arc distances between pairs, we calculatin' them all
  Predictors of genetic distances, yo, we stand tall
  
  26 genetic systems, we calculatin' on the side
  Independent from the ethnohistorical ride
  We find correlations, connections that be strong
  Holdin' geographic distance, yeah, that's the song
  
  Ethnohistorical distances, they explain so fine
  The genetic variation in modern populations, it's a sign
  These results, they robust, no errors they hide
  Even with simulated mistakes, we ride
  
  Randomization tests, we checkin' the flow
  Historical movements, they don't affect the show
  But the geographic locations, yo, they matter too
  They impact the ethnohistory-genetics brew
  
  We track the development, through time we glide
  The ethnohistory-genetics correlation, it won't hide
  Over the past 4200 years, it's been buildin' up strong
  Gradual and cumulative, yeah, that's the long song
