The results point to a long-lasting mosaic landscape of woodlands, grasslands, marshes, rivers and shallow-water habitats.

What did the findings show?

The carbon isotope values suggest the elephant lived in a consistently well-watered environment. Pollen recovered from the sediments reinforced that picture: the researchers found abundant wetland vegetation, including reeds, sedges, willow, tamarisk and aquatic plants.

These signals matter because they describe stability. The region does not appear to have been a harsh or erratic environment during this stretch of the Pleistocene. Instead, it looks like a dependable stretch of habitat with reliable water, grazing and cover.

The study's scope has limits, as the reconstruction rests on one individual animal plus the sediments at a single site. A single tooth records one elephant's lifetime, not an entire epoch. The researchers interpret their results within those constraints.

Why does this corridor matter for human origins?

The Hula Valley region sits within the Levantine Corridor — the land bridge connecting Africa and Eurasia. During the Pleistocene, both animals and human groups moved through this corridor, and environments like the one described in the study likely supplied the water and biological resources they needed to survive the journey.

"Understanding how humans and animals responded to environmental change hundreds of thousands of years ago helps us better understand the forces that shaped our species," Sharon said.

He added: "The availability of water, vegetation and animal resources shaped where humans and wildlife could survive."

In other words, the geography of migration and the geography of habitable landscape ran along the same lines. Where wetlands, rivers and woodlands held steady, wildlife and human toolmakers could persist and pass through.

"The wetlands, rivers and woodlands of the Hula Valley helped sustain life along one of the world's earliest migration corridors," Sharon said, "offering a rare opportunity to understand the ecological conditions that supported both animals and human populations nearly 700,000 years ago."

Who conducted the research?

The study brought together specialists across several fields:

• Hannah Farrell, University of Haifa — lead author
• Gonen Sharon, Tel-Hai University of Kiryat Shmona — excavation director
• Cheryl A. Makarewicz, University of Haifa — isotope studies
• Nimrod Marom, University of Haifa — archaeozoology
• Minji Jin and Dafna Langgut, Tel Aviv University — pollen studies

The paper, published as Hannah Farrell et al., "Elephant dental remains from the Acheulian site at North Bridge Acheulian–Gesher Benot Ya'aqov: hominin behavior and environmental implications," appears in Quaternary Science Reviews (2026), DOI: 10.1016/j.quascirev.2026.110277.

The takeaway is a modest but striking one: a single molar, sitting in the dirt next to ancient handaxes for 700,000 years, can still tell researchers where the rivers ran, which trees lined them, and who — elephant or human — depended on them.
