Age-depth model with δ13Cca and δ18Oca isotope profiles for stalagmite Y99 growth interval-I

DOI

The Arabian Peninsula was one key area for H. sapiens dispersals out of Africa. Current dispersal models advocate that dispersals via the "southern route" into Arabia occurred during Glacial Termination-II (T-II), when increased monsoon precipitation and reduced sea-level and Bab-al-Mandab width increased the likelihood of crossing. The precise phasing between sea-level and monsoon precipitation is thus key to assess the likelihood of a successful crossing or the behavioural and technological capacities that facilitated crossing. Based on a precisely-dated stalagmite record from Yemen we reveal a distinct phase-lag of several thousand years between sea-level rise and monsoon intensification. Pluvial conditions in southern Arabia during MIS 5e lasted from ~127.7 to ~121.1 ka BP and occurred when sea-levels were already higher than at present. We propose three models for the dispersal of H. sapiens; all have pertinent implications for our understanding of human technological and behavioural capacities during MIS 5e.
