Réseaux et migrations préhistoriques

The past half century has seen a move from a multiregionalist view of human origins to widespread acceptance
that modern humans emerged in Africa. Here the authors argue that a simple out-ofAfrica model is also outdated,
and that the current state of the evidence favours a structured African metapopulation model of human origins.

Hunter-gatherers adjust mobility to maintain contact under climatic variation
Matt Grove
Journal of archeological science, 2018

Results suggest that the previously established strong reciprocal relationship between population density and mobility is not due purely to common determination by climatic variables. Instead, the best supported model is consistent with the hypothesis that hunter-gatherers adjust levels of mobility so as to maintain contact with neighbouring groups at varying population densities. This ensures that opportunities for cultural transmission are maintained at similar levels regardless of climatic variation. The results lead to a number of archaeologically testable predictions concerning the relationships between climatic variables, population density, mobility, and assemblage complexity.

Female exogamy and gene pool diversification at the transition from the Final Neolithic to the Early Bronze Age in central Europe
Knipper et al.
PNAS, 2017

We demonstrate that a simple notion of “migration” cannot explain the complex human mobility of third millennium BCE societies in Eurasia. On the contrary, it appears that part of what archaeologists understand as migration is the result of large-scale institutionalized and possibly sex- and age-related individual mobility.

Les réseaux sociaux à l’époque gravettienne
Luc Moreau
Pour la Science, 2012

À partir des indices retrouvés dans divers sites gravettiens, nous allons montrer que ces marcheurs infatigables entretenaient des réseaux d’échanges à grande distance par lesquels circulaient perles et ressources diverses, mais aussi des idées, et sans doute des femmes…
Human population dispersal ‘‘Out of Africa’’estimated from linkage disequilibrium and allele frequencies of SNPs
McEvoy et al.
Genome research, 2011
. Estimates of divergence times between European–African andEast Asian–African populations are inconsistent with its simplest manifestation: a single dispersal from the continent followedby a split into Western and Eastern Eurasian branches. Rather, population divergence times are consistent with substantialancient gene flow to the proto-European population after its divergence with proto-East Asians, suggesting distinct, earlydispersals of modernH. sapiensfrom Africa. We use simulated genetic polymorphism data to demonstrate the validity of ourconclusions against alternative population demographic scenarios.

The Deep Structure of Human Society: Primate Origins and Evolution
Bernard Chapais
Springer, 2009

The concept of deep structure points to the following human universals: stable breeding bonds and their correlate, fatherhood; the multifamily community; strong siblingships; bilateral (uterine and agnatic) kin recognition; incest avoidance; out-marriage (exogamy); matrimonial exchange; dual-phase residence (pre/postmarital); lifetime bonds between dispersed kin; bilateral relations between in-laws; kin-biased and affinity-biased marriage rules; and between-group alliances (supragroup levels of social organization).
