ABSTRACT
During the course of human evolution, lithic
technology became a critical element of hominin
foraging ecology and a contributor to feedback
loops selecting for increasingly sophisticated
tool use, cognition, and language. Here we
review the first million years of technology,
from 3.3 million years ago (Ma) to 2.3 Ma. This
time interval includes the two oldest
archaeological industries (the Lomekwian and
the early Oldowan) known exclusively from Africa,
which collectively overlap with four genera of
hominins (human relatives and ancestors). These
Early Stone Age (ESA) industries focused on the
production and use of sharp edges for cutting,
as well as the use of larger, sometimes unworked
stones for pounding. We review our current
understanding of these technologies, where they
were found, how they were made, what they were
used for, and the hominins that could have
produced them, and consider them in the context
of nonhuman primate archaeology.
