1. Brit-Am Vindicated: Cohen Gene Can Appear Independently without Familial Connexion

It's plausible that clades I (M170, M258, P212, P38, P19, U179) and J (12f2.1, M304, S35, S34, S6) diverged in the northern areas of the Levant, with clade I shortly after, spreading westward into western Europe, while clade J largely remaining largely localized then and expanding in situ. From several works, it appears that the J2 (M172) clade emerged first, and then later, J1 (M267) [See Ekins et al., An Updated Worldwide Characterization of the Cohen Modal Haplotype; and Nebel et al. 2001, The Y Chromosome Pool of Jews as Part of the Genetic Landscape of the Middle East]; the former likely emerged in the confines of the more northerly area of the Levant, while the latter, likely in a more southwardly region of the Levant [see Nebel et al. 2001]. According to Ekins et al., the bearing of the Cohen Modal Haplotype (CMH) STRs locus in the divergent clades of J2 and J1 implies that perhaps a derived haplotype cluster fundamental to CMH emerged some time before the divergence of either J2 and J1 from a shared ancestral lineage...

##It is possible that the originally defined CMH represents a slight permutation of a more general Middle Eastern type that was established early on in the population prior to the divergence of haplogroup J. Under such conditions, parallel convergence in divergent clades to the same STR haplotype would be possible.## - Ekins et al.

Problems with DNA and Lost Israelite Scenarios
RE: Brit-Am Now no. 1395
5. Cam Rea: Agrees with Nathan Pround

Hello Yair.  Seeing Cam Rea's note in Brit-Am 1595 with link to Nathan Proud's letter in Brit-Am 1394, I went back and read that letter. While on the face of it it may seem logical, when you look at the facts of the genetic drift of other family groups with relationship to Judah, it just doesn't hold up.  Take for instance the Ishmaelites, who were directly split off from the gene pool of what became Israel and Judah when Abraham was instructed by God to heed Sarah's demand and sent his son Ishmael away to become the father of the Arabs of today.  They didn't even have the "worse case" scenario Nathan Proud presents of 100 years with Judah.  And yet they are very close genetically to Judah today.  As are Edomites, whose progenitor Esau was split off a generation later.

And Judah and Israel were together far longer than 100 years.  They were together through the captivity in Egypt, through the wilderness of Sinai where even their place in the encampments with the rest of the tribes with the standards of each are described in Scripture, and so too right through the time of the Judges and the first three kings of Israel, Saul, David and Solomon.  And even after until Israel was carried away captive by Assyria there were still people from each intermingling with the other.  Minor splinter groups leaving prior to this don't figure in to the history of Judah together with Israel at all.  But if genetics tells us anything about relationships, then the relationships of the descendants of Ishmael and Esau (Edom) to Judah today give clue that even those splinter groups would show today their relationship in their dna, were we to know who and where they are.

3. Creativity & psychosis: Nuts and Guts go together 
Brit-Am Pre-amble:
The extract below suggests that creative people may tend to be more psychologically abnormal than others.

Possible confirmation of folk wisdom?
Genes for Psychosis and Creativity: A Promoter Polymorphism of the Neuregulin 1 Gene Is Related to Creativity in People With High Intellectual Achievement:
Why are genetic polymorphisms related to severe mental disorders retained in the gene pool of a population? A possible answer is that these genetic variations may have a positive impact on psychological functions. Here, I show that a biologically relevant polymorphism of the promoter region of the neuregulin 1 gene (SNP8NRG243177/rs6994992) is associated with creativity in people with high intellectual and academic performance. Intriguingly, the highest creative achievements and creative-thinking scores were found in people who carried the T/T genotype, which was previously shown to be related to psychosis risk and altered prefrontal activation.
