Neolithic settlement dynamics in 🇩🇪 are governed by different regional adaptation strategies and land-use systems based on e.g. climate ☀️ and soil properties 🌱. However, settlement preferences became more flexible over time due to agricultural diversification 🌾. www.sciencedirect.com/science/arti...

Displayed are the MP (blue triangle), AUR-P1 (solid red circle), and AUR-P2 sites (open red circle). Three special Aurignacian sites — Cardina-Salto do Boi, Abrigo de la Malia, and Lapa do Picareiro — are also indicated. The last Neanderthal (NEA) refugia are primarily located in coastal areas, delineated by a dashed blue circle. The initial expansion routes of anatomically modern humans (AMHs) associated with AUR-P1 are shown with thick solid red arrows. The subsequent Duero route, extending from Cantabria into inland Iberia, is represented by thick dashed red arrows. The expansion pathways of AMHs linked to AUR-P2 are marked by thin dashed red arrows. A potential zone of admixture between NEAs and AMHs is identified along the northern Iberian coast, enclosed by a white dashed circle.

Scientific coring campaigns in the Chew Bahir basin. Drilling pilot core CB-01-2009 close to the western basin margin in 2009, using a rotary single tube drill, with the cored sediment segments in the transport crate with a core diameter of 91 mm. Transect short cores across the basin were collected with a vibro-corer and smaller diameter liners. HSPDP deep-drilling campaign in November–December 2014, ∼ 3 km away from the western margin using duplicate coring strategy and soft-sediment coring tools (left: alien corer; right: extended nose corer, with non-rotating shoe). Six small ponds were excavated to store the daily required 40 000 L of drilling fluid per day. Recovered core segments were processed, weighed, measured and sealed for transport in the nearby science tent. Photos by the CHB science team.
