Pacifying Hunter-Gatherers, Raymond B. Hames Apr 2019

Pacifying Hunter-Gatherers, Raymond B. Hames

Anthropology Faculty Publications

There is a well-entrenched schism on the frequency (how often), intensity (deaths per 100,000/year), and evolutionary significance of warfare among hunter-gatherers compared with large-scale societies. To simplify, Rousseauians argue that warfare among prehistoric and contemporary hunter-gatherers was nearly absent and, if present, was a late cultural invention. In contrast, so-called Hobbesians argue that violence was relatively common but variable among hunter-gatherers. To defend their views, Rousseauians resort to a variety of tactics to diminish the apparent frequency and intensity of hunter-gatherer warfare. These tactics include redefining war, censoring ethnographic accounts of warfare in comparative analyses, misconstruing archaeological evidence ...


A Life History Perspective On Skin Cancer And The Evolution Of Skin Pigmentation, Daniel L. Osborne, Raymond B. Hames Jan 2014

A Life History Perspective On Skin Cancer And The Evolution Of Skin Pigmentation, Daniel L. Osborne, Raymond B. Hames

Anthropology Faculty Publications

The ancestral state of human skin pigmentation evolved in response to high ultraviolet radiation (UVR) stress. Some argue that pigmentation evolved to limit folate photolysis, therein limiting neural tube defects. Pigmentation also protects against sunburn which decreases the efficiency of sweating and potentiates skin infection. Pigmentation increases the efficacy of skin as a barrier to infection. Skin cancer has been rejected or minimized as a selective pressure because it is believed to have little or no effect on mortality during reproductive years. This argument ignores evidence of human longevity as a derived life history trait and the adaptive value of ...


Anthropological Data Regarding The Adaptiveness Of Hebephilia, Raymond B. Hames, Ray Blanchard Jan 2012

Anthropological Data Regarding The Adaptiveness Of Hebephilia, Raymond B. Hames, Ray Blanchard

Anthropology Faculty Publications

Hebephilia is the sexual attraction to early pubertal children in Tanner Stages 2 and 3, generally ages 11 through 14.

The second author of this letter (R.B.), a member of the Paraphilias Subworkgroup of the Work Group on Sexual and Gender Identity Disorders for DSM-5, proposed a diagnostic entity for DSM-5 that resembles the ICD-10 model, but with a different name: Pedohebephilic Disorder. In the original proposal (Blanchard, 2010a), this disorder would have three subtypes: pedophilic, hebephilic, and pedohebephilic. In the current version of the proposal, which is still under consideration, the name has been changed to Pedophilic Disorder ...
