Chapter 14: The
Emergence and
Dispersal of
Homo sapiens
Anatomically modern
Homo sapiens
Controversy
Replacement Models
• Phylogenic models that
suggest that modern
humans evolved in one
location and then
spread geographically,
replacing other earlier
hominin populations
without or with little
admixture.
Multiregional Models
• Phylogenic models that
suggest that modern
humans evolved in the
context of gene flow
between middle to late
Pleistocene hominin
populations from
different regions, so
that there is no single
location where modern
humans first evolved.
Which is correct?
Fossils: Africa
Fossils: Near East
Fossils: Europe
Fossil: Asia
Fossils: Australia
Modern Behaviors
• Microliths: small, flaked stone tools probably
designed to be hafted to wood or bone; common
feature of Upper Paleolithic and Later Stone Age
tool industries.
