Long before modern humans were thought to have arrived in Eurasia, advanced stone tool technologies were already present in Central Asia. Recent discoveries in Uzbekistan and Tajikistan reveal that blade tools resembling those of the Initial Upper Palaeolithic (IUP) date back as far as 70 000 years, which is prior to what was expected. This raises a crucial question: did modern humans reach the region earlier than previously believed, or did Neanderthals or Denisovans develop similar techniques independently? Key responsibilities: performing selected geochemical or biochemical analyses of sediment samples or artefacts; creating reference databases for the conducted analyses; coordinating other specialized laboratory analyses carried out within the project (including coordination of the selection of analytical methods and analysed materials).
