The site has yielded many artefacts with Lower Palaeolithic Acheulian cultures at the base of a thick stratified sequence, and overlying MP horizons.
"If Acheulian tools gave hominids an edge in Africa, then perhaps groups lacking that technology were forced to find resources elsewhere," Lepre says.
Their topics include tectonics, volcanism, and sedimentary paleo-environments during the Lower Pleistocene in the Lake Natron Basin, Tanzania; isotopic ecology and diets of fossil fauna from the T-1 paleosurface; the technology of the site complex; and the Acheulian sites from the south and north escarpments.
And the straightforward adaption of stone-working techniques to Acheulian bone tools, rather than the development of techniques better suited to exploit natural bone mechanics, also suggests a lack of foresight.
My view is that such changes only occurred after 300 000 years ago and are detected by changes in both human anatomy and the archaeological record: the transition from the Acheulian to Middle Stone Age/Mousterian technologies.
We know he was here because he left us what the dry-as-bones textbooks call ``a characteristic specimen of a Middle Acheulian hand axe''.
Hundreds of thousands of years, for instance, separated the transition from Oldowan to Acheulian stone techniques; the technical explosion of the Aurignacian period probably escaped its actors because of the very fact of the relative slowness of its pace.

Archaeologists categorize stone hand axes and related implements as Acheulian tools.
