Any new knowledge that goes beyond the stone tools and techniques used in the Palaeolithic and Mesolithic is most significant as it reveals the cultural and technical capabilities of the people living in these periods. In 1963, two pitch finds were discovered in a lignite open-mining pit in the northern foothills of the Harz Mountains, in a layer the geological age of which was dated as being older than 80,000 years. The great significance of these finds was therefore immediately apparent. One of the finds showed a fingerprint as well as the imprints of a flint stone tool and the structure of wood cells. This was indicative of the pitch piece having served as an adhesive to secure a wooden haft to a flint stone blade.Over 30 years later these finds were transferred to the Doerner Institut for investigation. The GC and GC/MS analyses revealed that, in both cases, birch pitches, well-known historical adhesives, had been used. These consist predominantly of pentacyclic triterpenoid components of the lupane type, with betulin forming the major component. The comparison with birch bark extracts showed that the biological peak profile (bio-marker) was surprisingly well preserved in these pitch finds and that hardly any degradation products were present.Today, comparable pitches can easily be produced with modern technical methods, i.e. using airtight laboratory flasks and temperature control facilities. However, any attempt at simulating the conditions of the Neandertal period and at producing these birch pitches without any of these modern facilities will soon be met with many difficulties. This implies that the Neandertals did not come across these pitches by accident but must have produced them with intent. Conscious action is, however, always a clear sign of considerable technical capabilities.

The straight-tusked elephants Palaeoloxodon spp. were widespread across Eurasia during the Pleistocene. Phylogenetic reconstructions using morphological traits have grouped them with Asian elephants (Elephas maximus), and many paleontologists place Palaeoloxodon within Elephas. Here, we report the recovery of full mitochondrial genomes from four and partial nuclear genomes from two P. antiquus fossils. These fossils were collected at two sites in Germany, Neumark-Nord and Weimar-Ehringsdorf, and likely date to interglacial periods ~120 and ~244 thousand years ago, respectively. Unexpectedly, nuclear and mitochondrial DNA analyses suggest that P. antiquus was a close relative of extant African forest elephants (Loxodonta cyclotis). Species previously referred to Palaeoloxodon are thus most parsimoniously explained as having diverged from the lineage of Loxodonta, indicating that Loxodonta has not been constrained to Africa. Our results demonstrate that the current picture of elephant evolution is in need of substantial revision.DOI: http://dx.doi.org/10.7554/eLife.25413.001

New absolute dates have been obtained for the Bilzingsleben (D.D.R.) archaeological site, using uranium‐series analyses of travertine, and electron spin resonance (ESR) analyses of travertine and tooth enamel of rhinoceros. The results indicate that the site was apparently occupied during interglacial isotope stages 9 or 11. The surrounding terrain has been subsequently dissected by at least three discrete stages of fluvial erosion during succeeding glacial stages. Bilzingsleben is thus shown to be significantly older than the Lower Travertine at the nearby site of Ehringsdorf, assigned to isotope stage 7 by uranium‐series dating. The latter assignment is confirmed by new ESR data presented here.
