What does the sum of the genetic, fossil, and archaeological evidence suggest regarding the relationship between Neandertals and modern Homo sapiens?
Neandertal genes are found in modern homo sapiens only in non Africans. Interbreeding only occurred after homo sapiens had migrated out of Africa.
21. According to the most recent evidence, the first modern Homo sapiens evolved in Africa around _______ years ago.
complete replacement hypothesis.
within the last 200,000 years ago modern homo sapiens emerged in Africa from speciation from homo heidelbergesis and migrated to the rest of the world replacing other premodern populations
partial replacement hypothesis
"mostly out of Africa hypothesis" no speciation occurred, the diverse archaic populations were assimilated into modern populations migrating out of Africa
Regional Continuity Hypothesis
"multi regional hypothesis" diverse populations in Africa Europe Asia and Australia, etc maintained their own evolutionary trajectory without significant replacement. Moderns evolved in parallel all over the old world. Implies that moderns directly evolved from homo erectus, neandertals and heidelbergensis.
The hypothesis that all modern humans descended from an African lineage is based on what kind of evidence?
Genetic evidence and fossil evidence. mt-DNA, mitochondrial eve.

Thus far, the earliest specimens of modern Homo sapiens are from which site?
Omo Kibish in Ethiopia. Omo1 is the earliest modern human found so far
Which site in Western Europe may offer evidence for genetic continuity between Neandertals and modern humans?
abrigo do lagar velho in Portugal
_______ is a site in southern France dated to 28,000 years ago. Fossil material from this site became the archetype for Upper Paleolithic Europeans.

The Upper Paleolithic culture period is divided into categories based on stone tool technologies. What are the names of these tool traditions?
Chatelperronian, Aurignacian, Gravettian, Solotrean, and Magdalenian
What is the benefit of an atlatl?
an atlatl is a wooden or bone hooked rod that acted to extend the hunters arm. It enhanced force and distance of a stone projectile tipped dart or short spear

Pacific Coastal Route
What presents the primary challenge to the theory that the Bering Land Bridge represented the first route for the first humans in the New World?
