SNP vs. STR YDNA TMRCA Estimation
An interesting comparison of YDNA TMRCA estimates using the SNP counting method and STRs (with both pedigree and Zhivotovsky rates as well as rho and ASD methods) can be found in a recently published study. The Y-chromosome tree bursts into leaf: 13,000 hig...

Assumptions on the genesis of artistic expression in humans shattered by Indonesian find.
Hand stencils and paintings of pigs found in Indonesian caves are cause for experts to rethink the genesis of artistic expression in humans according to a new publication in nature. Archaeologists have long been puzzled by the appearance in Europe ~40–35

When I did my DNA ethiohelix palestine I got some palestine admixture and wanted to know what populations of middle easterners and when the admixture took place in terms of length in time?
I was kind of shock because I dont recall anyone in the family ever mentioning that.

Mutation rate of the nuclear genome is getting a fossil calibration
The SMBE 2014 conference is showcasing a presentation where a 45,000 year old genome is being fully sequenced by Fu et al. and where the sequence will be used to calibrate, to my knowledge for the first time, the mutation rate of the nuclear genome. Previou...
