我们的研究证实,西西里岛和科索-撒丁岛的Testudo H.Hermanni拥有相同的mtDNA单倍型,而意大利半岛的乌龟拥有略有不同的单倍型。当考虑到化石记录时,这种惊人的模式与科西嘉岛和撒丁岛的局部灭绝以及后来被起源于其他地方的乌龟取代的想法非常一致,无论是通过自然的海外扩散还是人类的移位。
Our study confirms that Sicilian and Corso-Sardinian Testudo h. hermanni share a certain mtDNA haplotype, while tortoises from peninsular Italy harbour slightly different haplotypes. When the fossil record is considered, this striking pattern agrees well with the idea of local extinction in Corsica and Sardinia and later replacement by tortoises originating elsewhere, either by natural oversea dispersal or translocation by man.
