The recent resolutions of the CDEF-M168 tripartite structure to the bipartite DE-YAP and CF-P143 [16, 31] extends the conversation regarding the early successful colonization of Eurasia. While several scenarios remain potentially possible the most parsimonious model is the most prudent. This model proposes the successful colonization of Eurasia by migration(s) of populations containing precursor Y-chromosome founder macrohaplogroup CDET-M168 and basal mtDNA L3 representatives. Regions near but external to northeast Africa, like the Levant or the southern Arabian Peninsula could have served as an incubator for the early diversification of non-African uniparental haplogroup varieties like Y chromosome DE-YAP*, CF-P143* and mtDNA M and N molecular ancestors. These would have spread globally and diversified over time and space. This model would imply that both CF-P143 and the DEYAP evolved nearby but outside Africa. One DE-YAP* ancestor would have spread to Asia and evolved to haplogroup D while another DE-YAP* returned to northeast Africa and evolved into hg E.
The paper unfortunately uses the faulty "evolutionary mutation rate" for Y-STRs, hence its age estimates are wrong and should be roughly divided by 3.
This correction brings the age of Saudi Arabian J1-M267 to ~2,000BC, which corresponds exactly with the inferred linguistic divergence of the most populous clade of Semitic which includes Ugaritic, Aramaic, Arabic, and Hebrew. I have little doubt that the modality of J1 among Semitic populations such as Arabs or Jews can be traced to the Bronze Age expansion of Semitic populations from southwestern Asia.

Saudi Arabian Y-Chromosome diversity and its relationship with nearby regions
Khaled K. Abu-Amero et al.
Human origins and migration models proposing the Horn of Africa as a prehistoric exit route to Asia have stimulated molecular genetic studies in the region using uniparental loci. However, from a Y-chromosome perspective, Saudi Arabia, the largest country of the region, has not yet been surveyed. To address this gap, a sample of 157 Saudi males was analyzed at high resolution using 67 Y-chromosome binary markers. In addition, haplotypic diversity for its most prominent J1-M267 lineage was estimated using a set of 17 Y-specific STR loci.
Saudi Arabia differentiates from other Arabian Peninsula countries by a higher presence of J2-M172 lineages. It is significantly different from Yemen mainly due to a comparative reduction of sub-Saharan Africa E1-M123 and Levantine J1-M267 male lineages. Around 14% of the Saudi Arabia Y-chromosome pool is typical of African biogeographic ancestry, 17% arrived to the area from the East across Iran, while the remainder 69% could be considered of direct or indirect Levantine ascription. Interestingly, basal E-M96* (n=2) and J-M304* (n=3) lineages have been detected, for the first time, in the Arabian Peninsula. Coalescence time for the most prominent J1-M267 haplogroup in Saudi Arabia (11.6 +/- 1.9 ky) is similar to that obtained previously for Yemen (11.3 +/- 2) but significantly older that those estimated for Qatar (7.3 +/- 1.8) and UAE (6.8 +/- 1.5).
The Y-chromosome genetic structure of the Arabian Peninsula seems to be mainly modulated by geography. The data confirm that this area has mainly been a recipient of gene flow from its African and Asian surrounding areas, probably mainly since the last Glacial maximum onwards. Although rare deep rooting lineages for Y-chromosome haplogroups E and J have been detected, the presence of more basal clades supportive of the southern exit route of modern humans to Eurasian, were not found.
