I've seen somewhere the theory that Bronze or at least Tin ore was possibly traded between South East Asia and Mesopotamia or Egypt - could this be the link??<br /><br />More on sources of Tin here:<br />http://en.wikipedia.org/wiki/Tin_sources_and_trade_in_ancient_timespconroyhttps://www.blogger.com/profile/10312469574812832771noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-46220155214982505842010-08-16T22:38:47.612+03:002010-08-16T22:38:47.612+03:00http://members.bex.net/jtcullen515/haplotest.htm T...http://members.bex.net/jtcullen515/haplotest.htm The World Haplogroup an Haplo-I subclade predictor says...for I-P38 haplotype #1<br />Haplogroups and probabilities are as follows:<br />J2-M205 =>28% Q-Cluster1 =>13% E3b-V22 =>12% R1a1-English =>10% Ix-S23 =>6% H =>6% R2-M124-Cluster-B =>5% Q-M242-Group2 =>4% I-P37.2 =>3% E3b =>3% J1-M267 =>3% I-M253 =>1% R1b-IrishIII =>1% G , G2 =>1% E3a =>1% <br /><br />For I-P38 haplotype #2<br />Haplogroups and probabilities are as follows:<br />J2-M172 =>58% J2-M67 =>33% J2-M92 =>6% E3b-V12 =>2% <br /><br />Whit Athey's Haplogroup Predictor predicts for I-P38 haplotype #1<br /><br />Q with a fitness score of 36 and a probability of 97.6%...equal priors...and for other priors...strongly predicted Q with up 90% and up...<br /><br />For I-P38 haplotype #2<br /><br />Predicted as J2a1b with a fitness score of 57 and a probability of 86.5%...J2a1(xbh) with a fitness score of 52 and a probability of 13.0%, and J2a1h with a fitness score of 35 and a probability of 0.5%...all equal priors.

There are 7 R1b1b2 samples, all labeled as belonging to very different haplogroups, including E1b1a and E2b. The study claims no R1b1b2 was found. All 7 R1b1b2 have 393=13, aka European, while in contrast almost all R1b1b2 from Iran, Middle East, and the Indian sub-continent have 393=12.<br /><br />Normally, when a mislabel occurs, the haplogroup is assigned to a nearby branch. Definitely not the case in this study. I think these mistakes must be due to clerical mislabeling of the data after the fact, rather than outright misinterpretation of the results.<br /><br />They claim to have found 2 J*, which is believable overall but given the extreme errors in their study and the fact that these 2 J* samples have 438=9 and 438=10, and that coincidentally the other J samples are split evenly between J1 (438=10) and J2 (438=9) makes me think it's just another error. The supposed J* don't have a point mutation in DYS458, but neither do any of the J1 samples, despite that point mutations were noted for several samples, usually in DYS385.<br /><br />This is one of the lousiest y-dna studies ever. None of the SNP results should be considered valid unless their haplotype certifies the SNP result. Fortunately, they didn't botch the haplotypes, except for the lack of point mutations in DYS458 in J1.aargiedudehttps://www.blogger.com/profile/02885756901119408472noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-36542430097791020442010-08-16T17:13:31.686+03:002010-08-16T17:13:31.686+03:00Dienekes writes:

E-V22 is found in the Middle East, Mediterranean, The Horn of Africa, Sudan and Egypt. So being in the Comoros does not seem that surprising? (It could be expected in most likely scenarios?) <br /><br />E-V22 should be carefully distinguished from other forms of E-V78.<br /><br />Best Regards<br />AndrewAndrew Lancasterhttps://www.blogger.com/profile/15050253327442799011noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-11311734325783026032010-08-16T16:10:56.567+03:002010-08-16T16:10:56.567+03:00I was reading that Persians had settled the Easter...I was reading that Persians had settled the Eastern coast of Africa since the Sassanids.<br /><br />I had dismissed it as being some of sort of historical boast but this gene study does seem to show the extent of their settlement.<br /><br />I'm conditioned to think that most settlers/colonialists/explorers were invariably Western; good to know that Asiatics were in on the action as well :P<br /><br />Also strange that the Shirazis never hopped over to Madagascar. Its like the Malays & Arabs were the main presence in the Indian Ocean but very rarely overlapped one another.<br /><br />Either way its a fascinating history and something wroth exploring.Zachhttps://www.blogger.com/profile/13127382384826876357noreply@blogger.com
