At present there has been very limited research into the environmental conditions that these populations encountered during MIS 5{\textendash}4. In this study, we present the results of an analysis of higher plant biomarkers (n-alkanes and n-alkanols) from the sediments at TPL to reconstruct the palaeovegetation of the site and the human fossils. The n-alkane $\delta$13C values demonstrate that H. sapiens encountered a predominantly C3 forest landscape in MIS 5 b-MIS 4 that prevailed until MIS 1. Observations of a fluctuation in $\delta$13C values across MIS 5 b-MIS 1 ($\sim$86{\textendash}3 ka) indicates that moisture availability was non-uniform, most likely resulting in landscape changes in and around TPL. The presence of H. sapiens at TPL during the environmental conditions associated with MIS 5 b-MIS 3 highlights the adaptability of our species to environmental dynamics at this time.}}, journal = {{Quaternary Science Reviews}}, volume = {325}, eid = {108471}, }
