“…Lower male N e can be caused by male reproductive skew, which is most strongly observed for wild sheep from N. America/Siberia. Female philopatry and male dispersal are often observed in wild sheep populations ( Garel et al 2022 ), which may also contribute to sex differences in reproductive success and lead to low male N e . Meanwhile, the extent of this spatial behavior can depend on the habitat structure shaped by natural and anthropogenic factors, which may cause the observed differences among lineages.…”

“…wild-living close relatives of domestic sheep (DOM), represent an interesting case for studying conservation genetics, with closely related lineages with distinct histories and conservation status. The ASM ( Ovis gmelini ; formerly Ovis orientalis ) is currently represented by three to five subspecies ranging through Armenia, Iraq, Iran, Turkey, and Cyprus ( Garel et al 2022 ). This group is considered to include the closest living relatives of the wild source population of DOM ( Hiendleder et al 2002 ; Chessa et al 2009 ; Cheng et al 2023 ; Wang et al 2023 ).…”

“…Although the native EUM populations were found in Sardinia and Corsica, these wild-living sheep are found today across Europe through recent human introduction. The EUM is generally recognized to represent feral populations of the earliest DOM stocks brought to Europe by people in the Early Neolithic (see Garel et al 2022 for a full discussion). Indeed, the group clusters with DOM Ovis aries based on their mitogenome ( Townsend et al 2019 ).…”

Once widespread in their homelands, the Anatolian mouflon (Ovis gmelini anatolica) and the Cyprian mouflon (Ovis gmelini ophion) were driven to near extinction during the 20th century and are currently listed as endangered populations by the IUCN. While the exact origins of these lineages remain unclear, they have been suggested to be close relatives of domestic sheep or remnants of proto-domestic sheep. Here, we study whole genome sequences of n = 5 Anatolian mouflons and n = 10 Cyprian mouflons in terms of population history and diversity, comparing them to eight other extant sheep lineages. We find reciprocal genetic affinity between Anatolian and Cyprian mouflons and domestic sheep, higher than all other studied wild sheep genomes, including the Iranian mouflon (Ovis gmelini). Studying diversity indices, we detect a considerable load of short runs of homozygosity (ROH) blocks (<2 Mb) in both Anatolian and Cyprian mouflons, reflecting small effective population size (Ne). Meanwhile, Ne as well as mutation load estimates are lower in Cyprian compared to Anatolian mouflons, suggesting the purging of recessive deleterious variants in Cyprian sheep under a small long-term Ne, possibly attributable to founder effects, island isolation, introgression from domestic lineages, or differences in their bottleneck dynamics. Expanding our analyses to worldwide wild and feral Ovis genomes, we observe varying viability metrics among different lineages, and a limited consistency between viability metrics and IUCN conservation status. Factors such as recent inbreeding, introgression, and unique population dynamics may have contributed to the observed disparities.

Phenotype transition from wild mouflon to domestic sheep

The domestication of animals started around 12,000 years ago in the Near East region. This “endless process” is characterized by the gradual accumulation of changes that progressively marked the genetic, phenotypic and physiological differences between wild and domesticated species. The main distinctive phenotypic characteristics are not all directly attributable to the human-mediated selection of more productive traits. In the last decades, two main hypotheses have been proposed to clarify the emergence of such a set of phenotypic traits across a variety of domestic species. The first hypothesis relates the phenotype of the domesticated species to an altered thyroid hormone-based signaling, whereas the second one relates it to changes in the neural crest cells induced by selection of animals for tameness. These two hypotheses are not necessarily mutually exclusive since they may have contributed differently to the process over time and space. The adaptation model induced by domestication can be adopted to clarify some aspects (that are still controversial and debated) of the long-term evolutionary process leading from the wild Neolithic mouflon to the current domestic sheep. Indeed, sheep are among the earliest animals to have been domesticated by humans, around 12,000 years ago, and since then, they have represented a crucial resource in human history. The aim of this review is to shed light on the molecular mechanisms and the specific genomic variants that underlie the phenotypic variability between sheep and mouflon. In this regard, we carried out a critical review of the most recent studies on the molecular mechanisms that are most accredited to be responsible for coat color and phenotype, tail size and presence of horns. We also highlight that, in such a complicate context, sheep/mouflon hybrids represent a powerful and innovative model for studying the mechanism by which the phenotypic traits related to the phenotypic responses to domestication are inherited. Knowledge of these mechanisms could have a significant impact on the selection of more productive breeds. In fact, as in a journey back in time of animal domestication, the genetic traits of today’s domestic species are being progressively and deliberately shaped according to human needs, in a direction opposite to that followed during domestication.

“…Both mouflon taxa are genetically and phenotypically closely related and are identified as two subspecies of Ovis gmelini [15]. The latter is currently represented by three to five subspecies ranging through Armenia, Iraq, Iran, Turkey and Cyprus [16]. Unlike the "Near Threatened" status assigned to the whole species, both O. g. ophion and O. g. anatolica are considered to be "Endangered" due to their small population sizes and continuing decline [12].…”

Once widespread in their homelands, Anatolian mouflon (Ovis gmelini anatolica) and Cyprian mouflon (Ovis gmelini ophion) were driven to near extinction during the 20th century and are currently listed as endangered populations by the IUCN. While the exact origins of these lineages remain unclear, they have been suggested to be close relatives of domestic sheep or remnants of proto-domestic sheep groups. Here, we study whole genome sequences of n=5 Anatolian mouflons and n=10 Cyprian mouflons in terms of population history and diversity, relative to eight other extant sheep lineages. We find reciprocal genetic affinity between Anatolian and Cyprian mouflons and domestic sheep, higher than all other studied wild sheep genomes, including the Iranian mouflon (Ovis gmelini). Despite similar recent population dynamics, Anatolian and Cyprian mouflons exhibit disparate diversity levels, which can potentially be attributed to founder effects, island isolation, introgression from domestic lineages, or different bottleneck dynamics. The lower relative mutation load found in Cyprian compared to Anatolian mouflons suggests the purging of recessive deleterious variants in the former. This agrees with estimates of a long-term small effective population size in the Cyprian mouflon. Both subspecies harbor considerable numbers of runs of homozygosity (ROH) blocks <2 Mb, which reflects the effect of small population size. Expanding our analyses to worldwide wild and feralOvisgenomes, we observe varying viability metrics among different lineages, and a limited consistency between viability metrics and conservation status. Factors such as recent inbreeding, introgression, and unique population dynamics may contribute to the observed disparities.
