Gene Expression

PLOS Genetics has a nice review titled The Jewels of Our Genome: The Search for the Genomic Changes Underlying the Evolutionarily Unique Capacities of the Human Brain. It is short and pithy and hits the major points (e.g., SNPs vs. duplications vs. gene expression), so I see no reason to offer any commentary or review of an an already satisfactory commentary and review. If you want original research articles in this area, go here. Some of the material is even open access now.

Update: John Hawks has more.
