"Things are looking mighty fine," announced the prehistoric invertebrate, taking measure of his surroundings through a series of small, hexagonal eyelets located at the tip of his thorax. "Sulfurous gas seems to be bubbling up to the surface pretty good, and several single-cell organisms appear to be mutating at a rather steady pace. Also, just today, I developed the ability to roll into a small protective shell in order to avoid predators".

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.

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.

Henry Gustav Molaison (February 26, 1926 – December 2, 2008), better known as HM or H.M., was a memory-impaired patient who was widely studied from the late 1950s until his death. His case played a very important role in the development of theories that explain the link between brain function and memory, and in the development of cognitive neuropsychology, a branch of psychology that aims to understand how the structure and function of the brain relates to specific psychological processes.
