“…Excluding lineages with signatures of recent European gene flow, Polynesian islanders have NRY lineages from Groups V-VIII Su et al 2000 b). Their Group V and VIII lineages derive from New Guinean populations, supporting the view that the East Asian ancestral group (carrying Group V lineages) assimilated genetic diversity in New Guinea (Kayser et al 2000 ;Underhill et al 2001). This is consistent with mtDNA Polynesian data, which shows the existence in low frequency of Melanesian lineages (Lum et al 1994).…”

Although molecular genetic evidence continues to accumulate that is consistent with a recent common African ancestry of modern humans, its ability to illuminate regional histories remains incomplete. A set of unique event polymorphisms associated with the non-recombining portion of the Y-chromosome (NRY) addresses this issue by providing evidence concerning successful migrations originating from Africa, which can be interpreted as subsequent colonizations, differentiations and migrations overlaid upon previous population ranges. A total of 205 markers identified by denaturing high performance liquid chromatography (DHPLC), together with 13 taken from the literature, were used to construct a parsimonious genealogy. Ancestral allelic states were deduced from orthologous great ape sequences. A total of 131 unique haplotypes were defined which trace the microevolutionary trajectory of global modern human genetic diversification. The genealogy provides a detailed phylogeographic portrait of contemporary global population structure that is emblematic of human origins, divergence and population history that is consistent with climatic, paleoanthropological and other genetic knowledge. 

“…After decades of refining both data and methods, such studies have provided insights into questions of human demography, migration, ancestry, adaptation and disease predispositions (Cavalli-Sforza et al 1994;Rosenberg et al 2002Rosenberg et al , 2005van de Vijver et al 2002;Ramachandran et al 2005;Tishkoff et al 2007;Li et al 2008). We can also infer the differing roles of males and females in the past from patterns in mitochondrial DNA (mtDNA) and non-recombining Y (NRY) portions of the genome, and the X chromosome (Seielstad et al 1998;Ramachandran et al 2004;Wilkins & Marlowe 2006;Segurel et al 2008;Keinan et al 2009).…”

“…Most studies agree that Fiji was the jumping-off point for the colonization of Polynesia, with the western Polynesian archipelagos of Tonga and Samoa settled earliest in Polynesia proper (Kirch & Green 2001). There also seems to be general agreement that Aotearoa (New Zealand) was settled most recently, although by whom is under dispute (Sutton 1994;Underhill et al 2001;Hurles et al 2003). For most of the rest of Polynesia there is no consensus, because dates for archaeological sites are still under revision, linguistic and anthropological data show much inter-island borrowing, and few islands have sufficient genetic data to draw conclusions.…”

Inferring population histories using cultural data

2009

The question as to whether cultures evolve in a manner analogous to that of genetic evolution can be addressed by attempting to reconstruct population histories using cultural data. As others have argued, this can only succeed if cultures are isolated enough to maintain and pass on a central core of traditions that can be modified over time. In this study we used a set of cultural data (canoe design traits from Polynesia) to look for the kinds of patterns and relationships normally found in population genetic studies. After developing new techniques to accommodate the peculiarities of cultural data, we were able to infer an ancestral region (Fiji) and a sequence of cultural origins for these Polynesian societies. In addition, we found evidence of cultural exchange, migration and a serial founder effect. Results were stronger when analyses were based on functional traits (presumably subject to natural selection and convergence) rather than symbolic or stylistic traits (probably subject to cultural selection for rapid divergence). These patterns strongly suggest that cultural evolution, while clearly affected by cultural exchange, is also subject to some of the same processes and constraints as genetic evolution.

“…It has been estimated that the victors killed 15%-50% of post-pubertal males and most infants and toddlers, and took females and most weaned pre-pubertal individuals captive (Lambert, 1997;Larsen, 1999;LeBlanc and Register, 2003;Maschner and Reedy-Maschner, 1998). These Neolithic patterns of intra-human killing have also been confirmed by studies of male lineages through the Y chromosome (Underhill et al, 2001) and of female lineages through mitochondrial DNA (Seielstad et al, 1998).…”

In light of the increasing threat of large-scale massacres such as terrorism against non-combatants (civilians), more attention is warranted not only to posttraumatic stress disorder (PTSD) but also to acute sociogenic pseudoneurological (bconversionQ) symptoms, especially epidemic sociogenic symptoms. We posit that conversion disorders are etiologically related to specific evolutionary pressures (inescapable threats to life) in the late stage of the human environment of evolutionary adaptedness (EEA). Bracha et al. have recently argued that from the neuroevolutionary perspective, medically unexplained efferent vasovagal syncope and medically unexplained craniofacial musculoskeletal pain in young otherwise healthy individuals, may be taxonomized as stress and fear-circuitry disorders. In the present article, we extend neuroevolutionary perspectives to acute pseudoneurological sociogenic (bconversiveQ) symptoms: psychogenic non-epileptic attacks (bpseudoseizuresQ), epidemic sociogenic disorders (DSM-IV-TR Epidemic bHysteriaQ), conversive motor deficits (pseudo-paralysis and pseudocerebellar symptoms), and psychogenic blindness. We hypothesize that these perplexing pseudoneurological stress-triggered symptoms, which constitute psychopathology in extant humans, are traceable to allele-variant polymorphisms which spread during the Neolithic EEA. During Neolithic warfare, conversive symptoms may have increased the survival odds for some noncombatants by visually (i.e., bnon-verballyQ) signaling to predatory conspecifics that one does not present a danger. This is consistent with the age and sex pattern of conversive disorders. Testable and falsifiable predictions are presented; e.g., at the genome-transcriptome interface, one of the major oligogenic loci involved in conversive spectrum disorders may carry a developmentally sensitive allele in a stable polymorphism (balanced polymorphism) in which the gene expression mechanism is gradually suppressed by pleiotropic androgens especially dehydroxyepiandrosterone sulfate (DHEA-S).
