From: Investigating population continuity with ancient DNA under a spatially explicit simulation framework
Simulation of spatial and temporal variance in the ancient population sample. Modern lineages are always taken in one single central deme (black square). a Ancient lineages are drawn in groups of 5 in 5 different demes, separated geographically with increasing distance from the centre, along the two diagonals, SP-H1 is the least dispersed and SP-H7 the most dispersed. b The same principle is applied for the temporal variation in ancient sampling, with TP-H1 being the least variable and TP-H4 the most. A homogenous sampling (time and location) is shown for comparison (all 25 ancient lineages taken in the black square)
