Mapping human genetic diversity in Asia
Out in today's Science is Mapping Human Genetic Diversity in Asia
Asia harbors substantial cultural and linguistic diversity, but the geographic structure of genetic variation across the continent remains enigmatic. Here we report a large-scale survey of autosomal variation from a broad geographic sample of Asian human populations. Our results show that genetic ancestry is strongly correlated with linguistic affiliations as well as geography. Most populations show relatedness within ethnic/linguistic groups, despite prevalent gene flow among populations. More than 90% of East Asian (EA) haplotypes could be found in either Southeast Asian (SEA) or Central-South Asian (CSA) populations and show clinal structure with haplotype diversity decreasing from south to north. Furthermore, 50% of EA haplotypes were found in SEA only and 5% were found in CSA only, indicating that SEA was a major geographic source of EA populations.
BEAST v1.5.3 released
Version 1.5.3 of BEAST (the most powerful Bayesian phylogenetics software available), has been released. Lots and lots of bugfixes!
Crux – A python library for molecular phylogenetics
Crux is a software toolkit for molecular phylogenetic inference that runs on (at least) Linux, FreeBSD, and Mac OS X. It is structured as a set of Python modules, which makes it possible to quickly develop Python scripts that perform unique, non-canned analyses.
A Cognitive Typology of Religious Actions
Justin Barrett and Brian Malley have a rather intriguing paper out in the Journal of Cognition and Culture: A Cognitive Typology of Religious Actions (doi:10.1163/156853707X208486):
The rapid but disproportionate growth of the cognitive science of religion in some areas, coupled with the desire to meaningfully connect with more traditional, function-inspired classifications, has left the field with an incomplete and sometimes inconsistent typology of religious and related actions. We address this shortcoming by proposing a systematic typology of counterintuitive actions based on their cognitive representational structures.
This typology may serve as the framework of a research program that seeks to establish (1) psychologically, whether each class of events receives different cognitive treatment within a given context and similar representation across contexts; and (2) anthropologically, whether the different classes are characterized by different performance frequencies, social functions, and kinds of interpretations, making them useful explanatory and predictive distinctions.
