Communicated by F. Ordon. Abstract According to a widely accepted theory on barley domestication, wild barley (Hordeum vulgare ssp. spontaneum) from the Fertile Crescent is the progenitor of all cultivated barley (H. vulgare ssp. vulgare). To determine whether barley has undergone one or more domestication events, barley accessions from three continents have been studied (a) using 38 nuclear SSR (nuSSRs) markers, (b) using five chloroplast SSR (cpSSR) markers yielding 5 polymorphic loci and (c) by detecting the differences in a 468 bp fragment from the non-coding region of chloroplast DNA. A clear separation was found between Eritrean/Ethiopian barley and barley from West Asia and North Africa (WANA) as well as from Europe. The data from chloroplast DNA clearly indicate that the wild barley (H. vulgare ssp. spontaneum) as it is found today in the “Fertile Crescent” might not be the progenitor of the barley cultivated in Eritrea (and Ethiopia). Consequently, an independent domestication might have taken place at the Horn of Africa.

Consistent with my 'pre-existing' viewpoint about the Neolithic of the African Horn being independent from southwest Asian Neolithic, but rather, with an east African provenance.

Very interesting. I don't know how I could have missed this. It's too bad you need to pay to read the full article. Does anyone have access to it, or want to buy it and share with the rest of us? Myra? Anyone?

Bump. I'd really love to read this article if anyone has more information about it (i.e. access, or access to related articles).

^If it's a new publication, as its dating suggests, then you'll likely have to pay to get access to it online. Otherwise, your nearest university/college library would be the next place to check.

I've checked it out, and unfortunately I only have online access to issues including Oct 2006 and before, but not Nov, Dec, Jan, or Feb (when this study came out), at least not online. I'll check for hard copies, but this means that I can provide anyone with access to previous studies if they ask me (pm).
