Extended Data Fig. 6: Comparison of the palaeo-data and palaeo-model.
From: Human origins in a southern African palaeo-wetland and first migrations
a, Locations of key sites that are used for the comparison of the palaeo-model and palaeo-data in this study are highlighted in red. The map was generated in Paraview v.5.6 (https://www.paraview.org/). b, Simulated tree fraction (%) at Horn of Africa (land grid points nearest to RC09-166) (grey, dark-blue bars) and stable hydrogen isotopic composition of leaf wax, corrected for ice volume contributions from the Gulf of Aden marine sediment core RC09-16630 (orange), indicating changes in hydroclimate. c, Relative precipitation changes (%) simulated by LOVECLIM transient model (all forcings) for 11° E, 19° S (grey, dark-blue bars) and grain-size aridity index reconstructed from sediment core MD96-209432 (orange). d, Grass fraction changes simulated by LOVECLIM transient model (all forcings) at 11° E, 14–17° S (grey, dark-blue bars) and reconstructed δ13C changes of n-alkanes (orange) (South Atlantic sediment core MD08-3167) indicative of abundance of C3 and C4 plants in the Namibian desert and further inland33.
