Mitochondrial DNA A DNA Mapp Seq Anal. 2018 Jan;29(1):147-157. doi: 10.1080/24701394.2016.1258406. Epub 2016 Dec 30.
The Western North African population was characterized by the presence of Iberomaurusian civilization at the Epiplaeolithic period (around 20,000 years before present (YBP) to 10,000 YBP). The origin of this population is still not clear: they may come from Europe, Near East, sub-Saharan Africa or they could have evolved in situ in North Africa. With the aim to contribute to a better knowledge of the settlement of North Africa we analysed the mitochondrial DNA extracted from Iberomaurusian skeletons exhumed from the archaeological site of Afalou (AFA) (15,000-11,000 YBP) in Algeria and from the archaeological site of Taforalt (TAF) (23,000-10,800 YBP) in Morocco. Then, we carried out a phylogenetic analysis relating these Iberomaurusians to 61 current Mediterranean populations. The genetic structure of TAF and AFA specimens contains only North African and Eurasian maternal lineages. These finding demonstrate the presence of these haplotypes in North Africa from at least 20,000 YBP. The very low contribution of a Sub-Saharan African haplotype in the Iberomaurusian samples is confirmed. We also highlighted the existence of genetic flows between Southern and Northern coast of the Mediterranean.
西北非人口的特点是在旧石器时代晚期（距今约20000年至10000年）存在伊比罗莫拉维亚文明。该人口的起源仍不明确：他们可能来自欧洲、近东、撒哈拉以南非洲，或者可能在北非原地演化。为了有助于更好地了解北非的定居情况，我们分析了从阿尔及利亚阿法卢（AFA）考古遗址（距今15000 - 11000年）和摩洛哥塔福拉尔特（TAF）考古遗址（距今23000 - 10800年）出土的伊比罗莫拉维亚骨骼中提取的线粒体DNA。然后，我们对这些伊比罗莫拉维亚人与61个当前地中海人群进行了系统发育分析。TAF和AFA样本的遗传结构仅包含北非和欧亚母系谱系。这些发现证明了这些单倍型至少在距今20000年前就在北非存在。伊比罗莫拉维亚样本中撒哈拉以南非洲单倍型的贡献非常低这一点得到了证实。我们还强调了地中海南北海岸之间存在基因流动。
