There is a recent scientific paper having, so far, the most comprehensive information regarding the origins of our own J-L24 clade. In this paper L24 is called M530. In the scientific community the official clade name is taken from the first published paper to discuss it and it turns out that Dr. Roy King was the first to discuss our L24 clade in a scientific paper The Coming of the Greeks to Provence and Corsica and he called it M530 in accordance to the nomenclature used by Stanford University. I think after over 3 years it is almost too late for us to shift from the L24 to the M530 name, maybe slowly, but just remember that L24 and M530 are one and the same mutation, clade, and branch of the Y-chromosome tree.
The paper is by Grugni V, Battaglia V, Hooshiar Kashani B, Parolo S, Al-Zahery N, et. al. (2012, Ancient Migratory Events in the Middle East: New Clues from the Y-Chromosome Variation of Modern Iranians. PLoS ONE 7(7): e41252. doi:10.1371/journal.pone.0041252. Here is a link to the paper: Ancient Migratory Events in the Middle East: New Clues from the Y-Chromosome Variation of Modern Iranians. The paper is free to download and don't forget to download the extensive supporting information files. This paper along with Dr. King's paper places our J-L24 (M530) haplogroup firmly within the population genetics scientific arena. We can expect to see more papers discussing J-L24(M530) in the future. A great step forward for our clade!
I wrote a summary of the L24(M530) aspects of the paper and it is posted on the The J-L24-Y-DNA Project News Section for 14 Nov 2012. I will repost my comments here later as individual news items in the FTDNA Project News section cannot be linked to.
I had an very enjoyable time studying and thinking about this interesting paper by Grugni et al (2012) and I hope that you will too.
