Bird bones from domestic midden deposits on Hegranes, North Iceland, dating AD 870-1104, are mostly puffin (Fratercula arctica) and guillemot (Uria aalge)—diving seabirds in the Alcidae family. We find that wings significantly overrepresented compared to legs, particular, proximal wing systematically more common than if whole birds were deposited middens. Trends wing-leg index distal suggest wh...

Animal movements in the Kenya Rift Valley today are influenced by a combination of topography and trace nutrient distribution. These patterns would have been the same in the past when hominins inhabited the area. We use this approach to create a landscape reconstruction of Olorgesailie, a key site in the East African Rift with abundant evidence of large-mammal butchery between ~1.2 and ~0.5 Ma ...

The Early Pleistocene (2.58–0.78 Ma) was a period of major evolutionary changes in the hominin lineage. progressive consolidation bipedal locomotion, alongside increases cranial capacity and behavioural flexibility, allowed early Homo to exploit an increasing diversity resources environmental settings within changing landscapes East Africa beyond. These complex processes were not necessarily li...

Abstract Direct evidence of ancient human occupation is typically established through archaeological excavation. Excavations are costly and destructive, practically impossible in some lake wetland environments. We present here an alternative approach, providing direct from sediments using DNA metabarcoding, steroid lipid biomarkers (bile acids) traditional environmental analyses. Applied to ear...
