Abstract

BACKGROUND: Most genetic studies on modern cattle have established a common origin for all taurine breeds in the Near East, during the Neolithic transition about 10 thousand years (ka) ago. Yet, the possibility of independent and/or secondary domestication events is still debated and is fostered by the finding of rare mitochondrial DNA (mtDNA) haplogroups like P, Q and R. Haplogroup T1, because of its geographic distribution, has been the subject of several investigations pointing to a possible independent domestication event in Africa and suggesting a genetic contribution of African cattle to the formation of Iberian and Creole cattle. Whole mitochondrial genome sequence analysis, with its proven effectiveness in improving the resolution of phylogeographic studies, is the most appropriate tool to investigate the origin and structure of haplogroup T1. METHODOLOGY: A survey of >2200 bovine mtDNA control regions representing 28 breeds (15 European, 10 African, 3 American) identified 281 subjects belonging to haplogroup T1. Fifty-four were selected for whole mtDNA genome sequencing, and combined with ten T1 complete sequences from previous studies into the most detailed T1 phylogenetic tree available to date. CONCLUSIONS: Phylogenetic analysis of the 64 T1 mitochondrial complete genomes revealed six distinct sub-haplogroups (T1a-T1f). Our data support the overall scenario of a Near Eastern origin of the T1 sub-haplogroups from as much as eight founding T1 haplotypes. However, the possibility that one sub-haplogroup (T1d) arose in North Africa, in domesticated stocks, shortly after their arrival from the Near East, can not be ruled out. Finally, the previously identified "African-derived American" (AA) haplotype turned out to be a sub-clade of T1c (T1c1a1). This haplotype was found here for the first time in Africa (Egypt), indicating that it probably originated in North Africa, reached the Iberian Peninsula and sailed to America, with the first European settlers.

  • Approximately 7000 years ago, taurine cattle were distributed in southern Egypt and across the African continent, established by the T1 mtDNA lineage, which is now characteristic of African cattle.

    “Approximately 7000 years ago, taurine cattle were distributed in southern Egypt and across the African continent, established by the T1 mtDNA lineage, which is now characteristic of African cattle [26,37,38,45].”

    From The Genomic Landscape of Cattle: Domestication, Dispersal, and Adaptive Evolution (2026) · cites this paper as [38]

    The Introduction (page unavailable) says T1 is almost fixed in modern African cattle, and the Discussion, ‘The origin of haplogroup T1’ (page unavailable), discusses possible routes by which domesticated taurine cattle entered Africa, including a route to Egypt. Neither passage establishes that cattle were distributed in southern Egypt and across the African continent approximately 7,000 years ago; the paper presents the migration routes as a possible explanation, not a dated finding.

  • All African cattle breeds analyzed so far carried taurine mtDNA haplotypes, which suggests that the waves of indicine arrival into Africa were male-mediated.

    “A study on mtDNA indicates that all African cattle breeds analyzed so far carried taurine mtDNA haplotypes which suggests that these waves of indicine arrival into Africa were male-mediated (Bradley et al., 1996; Bonfiglio et al., 2012).”

    From Identification of Candidate Signature Genes and Key Regulators Associated With Trypanotolerance in the Sheko Breed (2019) · cites this paper as Bonfiglio et al., 2012

    The Introduction (page not available) says taurine mtDNA haplogroup T1 is almost fixed in African cattle, supporting the broad maternal-lineage point but not the claim that all analyzed breeds carried taurine haplotypes. The Discussion section “The origin of haplogroup T1” (page not available) considers male-mediated input from local African aurochsen, not male-mediated waves of indicine cattle into Africa.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
