Migration, Adaptation & Culture in the Upper Paleolithic

Flashcards testing vocabulary, concepts, timelines, and adaptations associated with Upper Paleolithic human migration, social organization, technology, and environmental interactions.

Paleolithic Period

The Old Stone Age, spanning from approximately $2.6 \text{ MYA}$ to $13\text{,}000 \text{ YA}$ ($12\text{,}000 \text{ BP}$), characterized by the development and use of early stone tools.

Neolithic Period

 The New Stone Age, which followed the Paleolithic period and was marked by the rise of agriculture.

Upper Paleolithic Period

A sub-period spanning from $60\text{,}000$ to $12\text{,}000 \text{ YA}$ ($12\text{,}000 \text{ BP}$), defined by widespread Homo sapiens migration, extinction of other archaic humans, and rapid technological, artistic, and cultural changes.

Anatomical Traits of Homo Sapiens

Unique physical characteristics of modern humans, including a big round brain, a distinct lower jaw, a flat brow ridge, and a narrow body.

Pan-African Evolution Model

An evolutionary framework proposing that Homo sapiens did not originate from a single central point, but evolved in isolated pockets across Africa, with each group possessing distinct physical and technological qualities.

Out-of-Africa Migration (~60,000 YA)

The successful wave of Homo sapiens migration leaving Africa approximately $60\text{,}000 \text{ YA}$ across land bridges and through the Sinai Peninsula, to which all non-African human lineages can be traced.

Push-Pull Migration Factors

Environmental forces driving migration; drying conditions in North Africa served as a push factor, while luscious vegetation and abundant game in the Sinai and Arabian Peninsulas served as a pull factor.

Melanin

A natural pigment in human skin that acts as a natural sunscreen; variations in skin pigmentation evolved to balance protection against destructive UV rays with the absorption of UVB needed for synthesizing vitamin D.

Neanderthal Interbreeding

Interbreeding encounters between modern Homo sapiens and Neanderthals in Europe that transferred genetic traits controlling skin color and immune system response.

Extensification

The social mechanism by which human populations grew without overstripping local resources, occurring when larger groups split into smaller bands while keeping individual band sizes constant at roughly 20 to 150 people.

Exogamous Mating

The practice of seeking breeding partners from outside one's immediate social group, which reduced inbreeding and built social alliances between different bands.

Late Paleolithic Demographic Change

A shift during the late Paleolithic where increased adult longevity allowed grandparents to assist in child care, reducing infant mortality and driving rapid population growth.

Shamanism

A religious and spiritual belief system based on supernatural powers and connections with a spirit world, where specialized shamans used music, dancing, drugs, rituals, and sacrifices to communicate with spirits.

Intentional Environmental Burning

An early technique where humans deliberately set fire to vegetation to clear landscapes, alter habitats, improve game hunting, and encourage the growth of useful food plants.

Late Paleolithic Megafauna Extinctions

The widespread disappearance of large herbivorous animals, such as mammoths, caused by a combination of human environmental impacts, hunting, and climate change.
