Cross-over Immunoelectrophoresis sheds light on Levantine hominin subsistence during the Middle Pleistocene

8 August 2016

Excavations at Shishan Marsh, a former desert oasis in Azraq, northeast Jordan, reveal a unique ecosystem and provide direct family-specific protein residue evidence of hominin adaptations in an increasingly arid environment approximately 250,000 years ago.

A generalized stratigraphy associated with Middle Pleistocene occupations at SM-1. Based on lithic, faunal, paleoenvironmental and protein residue data, a team of archaeologists conclude that Late Pleistocene hominins were able to subsist in extreme arid environments through a reliance on surprisingly human-like adaptations including a broadened subsistence base, modified tool kit and strategies for predator avoidance and carcass protection.
