“…The estimated W f values obtained in the present experiment were lower than the real Canarian goat adult weight, referenced by Castro et al (2017) at 45 and 70 kg for females and males, respectively. It has been reported that Gompertz model can underestimate the asymptote constant in goats, especially when the kid's weighing age is limited to less of 4 months of life (Najari et al, 2007).…”

“…Considering the overall genetic make-up within the archipelago, the genetic diversity indices indicated that all values except those of the Palmera breed, are in line with the majority of the other analyzed breeds. The low genetic variability in terms of uHe and Ho, together with the high values of inbreeding in the Palmera breed probably reflect the greater isolation of this population in accordance with the geographic setting of the archipelago [ 6 , 19 , 34 ]. In addition, studies relying on the analysis of mtDNA in Canarian goat populations have suggested a pre-Hispanic origin with a stepping-stone pattern of diffusion across the islands [ 4 ], therefore, a strong founder effect is the most likely cause of the reduced variability observed by us and others.…”

Background The presence of goats in the Canary Islands dates back to the late 1st millennium BC, which coincides with the colonization by the Amazigh settlers. However, the exact geographic origin of Canarian goats is uncertain since the Amazigh peoples were distributed over a wide spatial range. Nowadays, three Canarian breeds (Palmera, Majorera and Tinerfeña) are officially recognized, along with two distinct South and North Tinerfeña ecotypes, with the South Tinerfeña and Majorera goats thriving in arid and dry semi-desertic environments and the Palmera and North Tinerfeña goats are adapted to humid and temperate areas that are influenced by trade winds. Genotypes for 224 Canarian goats were generated using the Illumina Goat single nucleotide polymorphism (SNP)50 BeadChip. By merging these data with the genotypes from 1007 individuals of African and Southern European ancestry, our aim was to ascertain the geographic origin of the Canarian goats and identify genes associated with adaptation to diverse environmental conditions. Results The diversity indices of the Canarian breeds align with most of those of the analyzed local breeds from Africa and Europe, except for the Palmera goats that showed lower levels of genetic variation. The Canarian breeds demonstrate a significant genetic differentiation compared to other populations, which indicates a history of prolonged geographic isolation. Moreover, the phylogenetic reconstruction indicated that the ancestry of the Canarian goats is fundamentally North African rather than West African. The ADMIXTURE and the TreeMix analyses showed no evidence of gene flow between Canarian goats and other continental breeds. The analysis of runs of homozygosity (ROH) identified 13 ROH islands while the window-based FST method detected 25 genomic regions under selection. Major signals of selection were found on Capra hircus (CHI) chromosomes 6, 7, and 10 using various comparisons and methods. Conclusions This genome-wide analysis sheds new light on the evolutionary history of the four breeds that inhabit the Canary Islands. Our findings suggest a North African origin of the Canarian goats. In addition, within the genomic regions highlighted by the ROH and FST approaches, several genes related to body size and heat tolerance were identified.

The Canary Islands were initially colonized around 200 CE by North African Berber populations who brought with them domestic plants and animals. These communities remained isolated until the arrival of Europeans in the Late Middle Ages which triggered the conquest of the archipelago. Its geostrategic location in the framework of Atlantic expansion facilitated the arrival of people, knowledge, goods, plants, and animals which served to shape the new Canarian society. This study explores the dietary practices of this period through the zooarchaeological analysis of the faunal remains recovered at the Hospital de San Martín (fifteenth to the eighteenth centuries), Las Palmas (Gran Canaria, Spain). Our results suggest that caprines were the main taxa consumed. This follows both the pre-colonial Indigenous tradition and, according to historical sources, the subsequent European period. The faunal assemblage recovered also reveals the first directly radiocarbon-dated cases in the Canary Islands of three hitherto unknown species: cattle, chicken, and rabbit. Moreover, the results evidence a progressive increase throughout the Modern Era of chicken and rabbit, and that translocating these new species to the archipelago during the European expansion led to a diversification of meat resources.
