From Arabia to Iberia: A Y chromosome perspective

The Eastern side of the Westernmost Europeans: Insights from subclades within Y‐chromosome haplogroup J‐M304

“…The predominant branch of J1a2b‐P58 found in Portugal, J1a2b2‐L147.1, had already been identified in different regions from Spain (Regueiro et al, ). The absence of J1a2b2a‐L222.2, a subclade of J1a2b2‐L147.1, is noteworthy given that it is well represented in Arabian and North African populations (eg Egypt) along with other J1a2b‐P58 lineages, but being the only J1 lineage in Tunisia and Morocco (Regueiro et al, ). In addition, J1a2b2a‐L222.2 was also absent in Spain (Regueiro et al, ).…”

In addition, J1a2b2a‐L222.2 was also absent in Spain (Regueiro et al, ). The estimated ages for J1a2b2a‐L222.2 varied from 2.03 ± 0.52 to 1.55 ± 0.50 kya in Northwest Africa and 2.10 ± 0.72 to 2.10± 0.56 kya in Arabia, and were considerably younger than for J1a2b2‐L147.1, whose time estimates are deeper and quite similar in Iberia and Arabia, ranging from 3.11 ± 0.85 to 5.82 ± 1.83 kya (Regueiro et al, ).…”

“…Located at the southwestern edge of Europe, the Iberian Peninsula has been subject to diverse population movements throughout pre‐history, including the first farmer migration during the Neolithic (Mathieson et al, ; Olalde et al, ), and, in historical times, the Arab‐Berber occupation and the Jewish diaspora (Adams et al, ; Botigué et al, ; Regueiro, Garcia‐Bertrand, Fadhlaoui‐Zid, Álvarez, & Herrera ). The study of Y‐chromosome diversity can offer important insights into the spread of paternal lineages through time.…”

Study of medieval critical samples—a genetic approach to the study of the Mudejar Community

“…No one of the studied individuals revealed characteristic Berber and/or Arabic haplogroups (U6 [1] and L1). Towards these results, we propose two different explanations.…”

“…Effectively, there were centuries of "cohabitation" between the three great religions of the Book: Christians, Jewish and Muslim peoples [1]. The "Mudéjares", as an Islamic community assimilated in medieval Castile, represented one of the most important cultural and economic bastions of the Iberian culture, largely keeping Islam and customs, but incrementing differences from Granada and North Africa.…”
