Then Nature published a review article by Bernard Wood and Terry Harrison on human evolution. It's nothing earth-shatteringly new, but it is consistent with Wood's skepticism about the ability of cladistics to resolve the phylogeny of hominin fossils. Specifically in this paper, they're trying to challenge the classification of Ardipithecus, Sahelanthropus, and Orrorin as hominins, or at the very least suggest that those three taxa may not obviously be hominins. They have a pretty dim view of applying cladistics to paleoanthropology, at least at this stage in our understanding.

And finally Science published a new paper from Hernandez et al. on selective sweeps in human evolution. They looked at variation in 179 human genomes and concluded,
These findings indicate that classic sweeps were not a dominant mode of human adaptation over the past ~250,000 years.Hernandez et al. 2011. Classic Selective Sweeps Were Rare in Recent Human Evolution. Science 331:920-924.
