Abstract of the abstract

  • East Africa origin concomitantly with expanding grasslands some 2 Ma
  • 4 parapatric lineages differentiated following Pleistocene bioclimatic cycles
  • Allopatric genetic divergence within savannah refuges during humid episodes
  • Dispersal during arid ones
  • Secondary contact zones around geographic barrier (Niger River and Lake Chad basins)
