The case of Jebel Irhoud 1

Bruner and Pearson 2013The cranial morphology of  Jebel Irhoud 1 still lacks a robust phylogenetic interpretation. Together with Osbjorn Pearson, we have just published on Anthropological Science a general synthesis on its neurocranial features. If we assume that this fossil is somehow related to the modern human lineage, the derived facial anatomy and plesiomorph neurocranial form lead to two main points. First, this braincase evolved by parallelism in both modern humans and Neandertal lineage, or else there is a unknown common ancestor with the same neurocranial organization. Second, the origin of the modern human brain is not strictly associated with the origin of the modern human lineage.

    There are some good comments about Jebel Irhoud on Dienekes’ and Mathilda’s Anthropology Blogs. You can also have a look at the 3D model of the skull at the Smithsonian website

  • How to become a super memorizer – and what it does to your brain
    New research shows that we can train our brains to become memory champions To many of us, having to memorize a long list of items feels like a chore. But for others, it is more like a sport. Every year, hundreds of these ‘memory athletes’ compete with one another in the World Memory Championships, memorising hundreds of words, numbers, or other pieces of inf […]
