This was followed by dna tests in the area "no Significant crypto-Jewish ancestry in Spanish Americans" 2006 Sutton, Knight, Underhill et al...which then brings us to a simpler explanation as the appearance of mtdna T2 in Spaniards vs. the sensational story of Jewish Cowboys being responsible for the death of millions of Native Americans...

At ...About comments: It is almost all of the above. At least it is in regard to the connection with northwestern Mexico’s T2e5. Dr. Bedford found the ideal “tribe” in this region founded in 1580’s by northern border Portuguese and South Andalusians and other colonizers. Many of them, men and women, were descendants of recent conversos, and had issues with the Inquisition (as did Luis de Carvajal and his famous family). <br />mt/Y set of markers, history, oral history, cultural history, our peculiar last names of patrilocal (trade and industry oriented) culture can be used to build the narrative. Lastnames like (de la) Garza, Chapa, Cavazos, and many have a very strong founder effect. <br />In a 450 years interval there were “explosions of particular y-DNA haoplogroups” by “socioeconomically successful men”. But autosomal DNA got NOT diluted that much due to a combination of isolation (this was the southernmost part of the Wild Wild West, we are the original cowboys) and sprit de corps, an identity barrier. <br />Next step looks very promising. The problem would be how to discern the difference with Phoenician and Moorish markers. Interestingly Sephardim is identified with people that migrated east. Those that were here migrated west, non-Ladino speakers.fmgarzamhttps://www.blogger.com/profile/17098537658554631893noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-37926565955177067692011-11-30T13:30:01.890+02:002011-11-30T13:30:01.890+02:00Pascvaks,

So you have these explosions of particular y-DNA haoplogroups wherever socioeconomically successful men went. But more often than not, their autosomal DNA got diluted to the point where one cannot ascribe them to any particular group, or phenotype, any longer.<br /><br />IMO, for population history, you need to drill down to an unprecedented sub-level to even understand the past 5,000 years, or so. <br /><br />Conversely, perhaps for the time frame of 50,000 to 130,000 ya, the concept of matching combined y- and mt-DNA migrations may be fruitful. After that? Fat chance. Women got around to such an extent that many haplogroups are global, semi-global, or at least widespread continentally. IMO, even if one were to drill down deeper into the mt-DNA tree, the time horizon beyond 2,000-3,000 ya surely becomes a tangled web.<br /><br />I am not saying it is impossible to trace migrations - just exceedingly hard, and IMO there is little correlation (in most case) between the two genders. And on distances of a few 1,000 km, diffusion and 'random walk' may often be more important than migrations.eurologisthttps://www.blogger.com/profile/03440019181278830033noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-36447102838290311602011-11-29T22:39:22.679+02:002011-11-29T22:39:22.679+02:00'FGS?'

And also, most cultures tend to be patrilocal.jes-rhttps://www.blogger.com/profile/13572668095214926909noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-24508365244247875342011-11-29T15:19:13.472+02:002011-11-29T15:19:13.472+02:00@Eze,

It may identify recent ethnic affiliations better if FGS is utilized on it, especially in patrilocal cultures.jes-rhttps://www.blogger.com/profile/13572668095214926909noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-13569201975124609922011-11-28T14:49:43.563+02:002011-11-28T14:49:43.563+02:00Curious!

In general, would not a combined mt/Y set of markers go further in identifying groups such as this, giving a much better "picture" of genetic identifiers for "tribal" populations?Pascvakshttps://www.blogger.com/profile/08311382875179534062noreply@blogger.com
