Archaic humans in the Middle Palaeolithic Levant conducted planned and selective intercepts of aurochs, but not mass hunting
Abstract While archaeologically challenging, determining whether hominins practised mass hunting before ca. 50,000 years ago is crucial for demonstrating intergroup communication and cooperation. The premise is that killing and processing several herd animals in a single event implicates planning, food sharing, and aggregation at a scale greater than most other Palaeolithic activities. Here, we focus on Unit III in the deep Middle Palaeolithic deposits of the Nesher Ramla karst depression (~ 120,000 years ago) in Israel, an early contact area of archaic and modern humans. Numerous aurochs ( Bos primigenius ) remains were found in this thin, temporally constrained stratigraphic unit, featuring signs of human butchery and consumption. An aurochs tibia displayed an embedded flint chip enveloped by bone remodelling, consisting unique evidence of recapture. We apply ageing, sexing, tooth wear and isotopic techniques to test the hypothesis that this assemblage represents mass hunting events but conclude that the evidence agrees better with multiple isolated, planned, and selective hunting and processing episodes. Thus, our results lend support to the commonly accepted view that Middle Palaeolithic archaic humans lived in small, dispersed, and disconnected groups, which might have been a disadvantage when faced with the sympatric modern humans.

Robust and localised control of a 10-spin qubit array in germanium
Abstract Quantum computers require the systematic operation of qubits with high fidelity. For holes in germanium, the spin-orbit interaction allows for electric, fast and high-fidelity qubit gates. However, the strong g-tensor anisotropy of holes in germanium and their sensitivity to the operational and environmental conditions challenge the operation of large qubit arrays. Here, we investigate a two-dimensional 10-spin qubit array with single-qubit gate fidelities above 99%, and obtain surprisingly uniform qubit properties. By tuning the hole occupation, we demonstrate control over the spin susceptibility, enabling fast plunger gate driving with Rabi frequencies consistently above 1.45 MHz/ (mV ⋅ T). Moreover, we probe the locality of electric dipole spin resonance and find that the configuration with three-hole occupancy driven by the associated quantum dot plunger gate reduces crosstalk, lowering it by an average factor of 2.5 to nearest neighbours, compared to single-hole plunger driving. Theoretical modelling points towards the pronounced anisotropy of p -like orbitals as the main mechanism with significant contributions through Coulomb interactions, giving directions for reproducible control of large qubit arrays.
