Fig. 4: Dispersal routes and population extend.
From: Reconstruction of human dispersal during Aurignacian on pan-European scale

a Population flux in (P km−1 10 yr−1) averaged over the period of 44–41 ka and the main human dispersal routes, including the Balkan, Alpine-East-Danube, Mediterranean-Coast and West-Europe routes. b Contours of ρ = 1 P 100 km−2 for 40, 39 and 37.8 ka showing the extend of occupation. Today’s topography is shaded grey.
