Combined GeophysicalrCoGeodynamic Analysis
of the Plio-Pleistocene Hominin Dispersal
Through the Levantine Corridor

Abstract
The origin of humans on Earth is closely
linked to understanding how ancient
populations dispersed into adjacent
territories. Traditionally, studies have
identified landscape and climatic changes
as the primary factors in this dispersal.
However, we propose that regional tectonic
and geodynamic factors also played a
significant role in shaping these movements.
To analyze this phenomenon, we employed
several primary methods, including
radiometric dating, magnetostratigraphy,
paleomagnetic correlation, isotoperCooxygen
analysis, tectonothermal studies, gravity
mapping, paleobiogeographic assessment,
lithofacies analysis, and event and cyclic
stratigraphy. Our research indicates that
the Akchagylian hydrospheric maximum,
which reached up to +200 m, significantly
limited the early dispersal of hominins
from Africa to Eurasia. The migration
corridor was shaped by tectonic activity
between the Dead Sea Transform and the
boundary of the Mesozoic Terrane Belt
carbonate platform. We argue that, during
the early stages of hominin evolution in
East Africa, the Levantine Corridor (LC)
had not yet developed into an optimal
route for dispersal, either tectonically
or paleogeographically. Suitable habitats
for early hominins emerged only after the
regression at the end of the Middle Gelasian,
around two million years ago, when sea level
fell by approximately 200 m, leading to the
dissection of the coastal high plateau of
the Eastern Mediterranean. We therefore
suggest that the LC became established only
after the termination of the Akchagylian
transgression and the subsequent landscape
reconfiguration of the Eastern Mediterranean.
Our integrated analysis, combining
paleomagnetic, structural, tectonic, and
event stratigraphy data, indicates that the
age of the renowned rCyUbeidiya site in
northern Israel is several thousand years
older than previously thought. This
paleogeographic impact had not been
considered in earlier studies. Considering
the diverse and complex factors that
governed hominin dispersal from Africa into
Eurasia within this multifaceted region, we
propose that the scope of research should be
broadened. Our detailed study of the Carmel
area, located northeast of the Levantine
Corridor and influenced by it during the
Pleistocene, indicates that this region
was inundated during the early phases of
hominin migration out of Eastern Africa.
Besides this, we have conducted an
integrated geologicalrCogeophysical
landscape analysis of the central part of
the Israeli coastal plain.
