“…There is high statistical support for the similarity despite the geographic distance between sites. As has been found in this study, camelid remains from Isla Mocha have also been identified as guanaco [90].…”

Were domestic camelids present on the prehispanic South American agricultural frontier? An ancient DNA study

The southern boundary of prehispanic farming in South America occurs in central Mendoza Province, Argentina at approximately 34 degrees south latitude. Archaeological evidence of farming includes the recovery of macrobotanical remains of cultigens and isotopic chemistry of human bone. Since the 1990s, archaeologists have also hypothesized that the llama (Lama glama), a domesticated South American camelid, was also herded near the southern boundary of prehispanic farming. The remains of a wild congeneric camelid, the guanaco (Lama guanicoe), however, are common in archaeological sites throughout Mendoza Province. It is difficult to distinguish bones of the domestic llama from wild guanaco in terms of osteological morphology, and therefore, claims that llama were in geographic areas where guanaco were also present based on osteometric analysis alone remain equivocal. A recent study, for example, claimed that twenty-five percent of the camelid remains from the high elevation Andes site of Laguna del Diamante S4 were identified based on osteometric evidence as domestic llama, but guanaco are also a likely candidate since the two species overlap in size. We test the hypothesis that domesticated camelids occurred in prehispanic, southern Mendoza through analysis of ancient DNA. We generated whole mitochondrial genome datasets from 41 samples from southern Mendoza late Holocene archaeological sites, located between 450 and 3400 meters above sea level (masl). All camelid samples from those sites were identified as guanaco; thus, we have no evidence to support the hypothesis that the domestic llama occurred in prehispanic southern Mendoza.

“…It is worthy of note that the Alpaca ( Vicugna pacos ) also differs from its closest wild relative at position 404 of AVPR1b, with a moderately radical change (GS = 121). Since AVPR1b is known to play an important role in behavior, this nonsynonymous substitution could have been important for the domestication of Alpaca in Pre-Hispanic South America ( Westbury et al , 2016 ). A role for AVPR1b in the behavioral changes associated with domestication is consistent with findings of a reduced basal plasma levels of ACTH in foxes subjected to rigorous artificial selection for domestication phenotypes over more than 50 years ( Trut et al , 2009 ): ACTH is an important hormone of the hypothalamic-pituitary-adrenal (HPA) axis, and its secretion in this axis is modulated by the AVPR1b receptor ( Kalsbeek et al , 2012 ; Terenina et al , 2013 ).…”

Oxytocin and arginine vasopressin systems in the domestication process

et al. 2018

Domestication is of unquestionable importance to the technological revolution that has given rise to modern human societies. In this study, we analyzed the DNA and protein sequences of six genes of the oxytocin and arginine vasopressin systems (OXT-OXTR; AVP-AVPR1a, AVPR1b and AVPR2) in 40 placental mammals. These systems play an important role in the control of physiology and behavior. According to our analyses, neutrality does not explain the pattern of molecular evolution found in some of these genes. We observed specific sites under positive selection in AVPR1b (ω = 1.429, p = 0.001) and AVPR2 (ω= 1.49, p = 0.001), suggesting that they could be involved in behavior and physiological changes, including those related to the domestication process. Furthermore, AVPR1a, which plays a role in social behavior, is under relaxed selective constraint in domesticated species. These results provide new insights into the nature of the domestication process and its impact on the OXT-AVP system.

“…It has a slight A þ T skewed (59.1%) and includes 22 tRNA (tRNA-Leu and tRNA-Ser occur in duplicate), 2 rRNA (rnl, rns), 13 genes involved in electron transport and oxidative phosphorylation, and 1 control region (CR). The mitogenome of the Huacaya breed is similar in length, content, and organization to other 14 Camelidae belonging to the genera Camelops Leidy, Camelus L., Lama, and Vicugna (Di Rocco et al 2010, Westbury et al 2016.…”

The domestic South American camelid Vicugna pacos L. is distributed along Peru, Chile, Bolivia, and Argentina. Here, we contribute to the bioinformatics and evolutionary systematics of the Camelidae by performing high-throughput sequencing analysis on the black Huacaya breed of V. pacos from Puno, Peru. The black Huacaya breed mitogenome is 16,664 base pairs (bp) in length and contains 37 genes (GenBank accession MT044302). The mitogenome shares a high-level of gene synteny to other Camelidae (Camelops, Camelus, Lama, and Vicugna). The mitogenome of the black Huacaya breed of V. pacos situates it in a clade with V. vicugna Molina, sister to Lama. We anticipate that further mitogenome sequencing of different breeds from Vicugna pacos will improve our understanding of the evolutionary history of this taxon.
