La Gomera is roughly circular, ~22 km in diameter and 370 sq.km in area. In spite of its small size, its central summit, Los Altos de Garajonay, reaches 1487 m above sea level. In addition, most of the island surface is >800 m above sea level with vertical cliffs around the coast, interrupted only by several narrow valleys that radiate from the centre to the sea. This rugged topography has hindered human travel within the island, as witnessed by the persistence till today of a whistled language used for communication over long distances.<sup><xref ref-type="bibr" rid="bib1">1</xref></sup> Sea travel was also difficult in the past. In fact, in contrast to archaeological evidence found on other islands of the archipelago, secondary intra-insular contacts of the pre-Hispanic aboriginals with La Gomera have not been demonstrated.<sup><xref ref-type="bibr" rid="bib2">2</xref></sup></p><p>Genetic evidence has pointed to a North African origin for the indigenous population, as well as a relatively high survival of the aboriginal gene pool in the modern mixed population. The strongest indigenous heritage has been observed in La Gomera, despite the high mortality rate of its aboriginal inhabitants during the European conquest in the fifteenth century.<sup><xref ref-type="bibr" rid="bib3">3</xref></sup> In previous AB0 system studies, La Gomera shows the highest 0 allele frequency (78%) of all the archipelago both at serological<sup><xref ref-type="bibr" rid="bib4">4</xref>, <xref ref-type="bibr" rid="bib5">5</xref></sup> and molecular<sup><xref ref-type="bibr" rid="bib6">6</xref>, <xref ref-type="bibr" rid="bib7">7</xref></sup> levels, resembling those found in aboriginal remains<sup><xref ref-type="bibr" rid="bib7">7</xref>, <xref ref-type="bibr" rid="bib8">8</xref></sup> and in North African Berber populations.<sup><xref ref-type="bibr" rid="bib6">6</xref>, <xref ref-type="bibr" rid="bib9">9</xref>, <xref ref-type="bibr" rid="bib10">10</xref></sup> Moreover, specific haplotypes of the CD4/Alu system also relate La Gomera to North African populations.<sup><xref ref-type="bibr" rid="bib11">11</xref>, <xref ref-type="bibr" rid="bib12">12</xref>, <xref ref-type="bibr" rid="bib13">13</xref></sup> These autosomal putative connections have been recently confirmed by a study using a wide number of informative ancestry markers, which estimated a remarkably higher North African ancestry for La Gomera (43%) compared with other islands.<sup><xref ref-type="bibr" rid="bib14">14</xref></sup></p><p>Without doubt, mtDNA has provided the most significant proof of the high aboriginal maternal heritage in the present day population of La Gomera. In a mtDNA study on the Macaronesian archipelagos, La Gomera behaved as an outlier compared with the rather homogenous Canarian group.<sup><xref ref-type="bibr" rid="bib15">15</xref></sup> This was mainly due to the fact that La Gomera has the highest frequency of the U6b1a mtDNA haplogroup (37%) compared with the other Canary Islands (~10%). This haplogroup is considered an aboriginal founder lineage,<sup><xref ref-type="bibr" rid="bib16">16</xref></sup> which has been fully confirmed by subsequent studies on aboriginal remains from Tenerife<sup><xref ref-type="bibr" rid="bib17">17</xref></sup> and La Palma.<sup><xref ref-type="bibr" rid="bib18">18</xref></sup> However, a Y-chromosome analysis of the current population was less conclusive, and genetic drift and/or sex-biased aboriginal gene flow to the postconquest population were proposed as the best explanation for these results.<sup><xref ref-type="bibr" rid="bib19">19</xref>, <xref ref-type="bibr" rid="bib20">20</xref></sup></p><p>The objective of this study was to directly assess the temporal evolution of the maternal aboriginal pool of La Gomera using mtDNA analysis on geographically ascribed samples from pre-Hispanic aboriginal remains and present-day samples collected from the six municipalities of the island.</p></sec><sec><title>Materials and methods</title><sec><title>Sample collection</title><p>Prehistoric samples were obtained from 10 different archaeological sites on La Gomera (<xref rid="tbl1" ref-type="table">Table 1</xref>; <xref ref-type="fig" rid="fig1">Figure 1</xref>; <xref ref-type="supplementary-material" rid="sup1">Supplementary Table S1</xref>). A total of 97 different individual samples (101 teeth) were collected avoiding direct handling. Teeth on the same mandible were available in four cases only and were replicated independently at the Las Palmas laboratory following the same protocols as for La Laguna. Samples from Vallehermoso were <sup>14</sup>C dated from 1600 to 1800 years before present.<sup><xref ref-type="bibr" rid="bib21">21</xref></sup> Stratigraphic level and burial characteristics confirmed the aboriginal nature of the rest of the samples.</p><p>A total of 326 maternally unrelated modern samples were also collected from the six municipalities of La Gomera (<xref ref-type="fig" rid="fig1">Figure 1</xref>): Alajeró (ALA), Agulo (AGU), Vallehermoso (VH), San Sebastián (SS), Hermigua (HER), and Valle Gran Rey (VGR). Informed consent and the birthplaces of all their known ancestors were anonymously facilitated. Municipality assignation was established only when the maternal ancestry of the donors was confirmed until the third generation; in the remaining cases (41), they were ascribed only to the total sample of La Gomera.

DNA yields of re-extractions were on average 66.6% of the previous extraction but with values ranging from 94.6 to 37.1%. Although we assayed various alternating extraction methods such as phenol/chloroform followed by the GuSCN-silica protocol and <italic>vice versa</italic>, the efficiency was similar to the currently used two consecutive GuSCN-silica extractions. This additional input of DNA was used to repeat genetic analysis of the same individual and to complete haplotypes of several samples when the first extract was finished. We were able to retrieve the sequence of the haplotypes from the anthropologist in charge of the physical measurements on the external tooth extraction in five instances but never in the endogenous extracts. Real-time PCR quantification allowed us to set the mean number of molecules used as initial PCR template at 2500–3000 copies. When the number of molecules obtained in the extractions was <250–100 copies/<italic>μ</italic>l and further DNA concentration was not possible due to unsolvable inhibition problems, the samples were discarded for the genetic analysis. Cloning was performed on 17 fragments in which heteroplasmy was detected, and in all cases, sequences with mutations included in the haplotypes of both researchers engaged in the molecular analysis were retrieved as well as some mutations attributed to miscoding lesions: 16014, 16219, 16232, and 16355 (<xref ref-type="supplementary-material" rid="sup1">Supplementary Table S4</xref>). Both-strand sequencing allowed the identification of the following phantom mutations: 16067, 16270, 16297, 16302, 16304A, 16316, and 16325. The 4 samples and 10 re-extractions replicated in Las Palmas gave identical results to those in La Laguna. In summary, 37 samples had to be discarded because of poor DNA yield (38.1%), unsolvable inhibition (3; 3.1%) or extraction contamination (5; 5.1%), while 52 informative mtDNA sequences were obtained from a total of 97 samples—an overall efficiency of 53.6%.</p></sec><sec><title>Aborigine mtDNA structure</title><p>At the time of the European conquest, La Gomera was subdivided into four political cantons named Hipalán, Mulagua, Orone and Agana, with some geographical correspondence to the current municipalities of San Sebastián, Hermigua-Agulo, Alajeró-Valle Gran Rey and Vallehermoso, respectively (<xref ref-type="fig" rid="fig1">Figure 1</xref>). Although during the fifteenth century an East–West boundary was politically recognized, it is known that previously a North–South boundary existed.<sup><xref ref-type="bibr" rid="bib34">34</xref></sup> The 52 aboriginal sequences analysed gave a total of 10 different haplotypes assorted into 8 haplogroups (<xref rid="tbl1" ref-type="table">Table 1</xref>), giving a whole gene diversity of only 55.88±7.75%. Subdivision of the samples into northern and southern areas showed that the autochthonous U6b1a haplogroup was overwhelmingly dominant on the island (<xref rid="tbl2" ref-type="table">Table 2</xref>). However, there were significant differences between areas due to the exclusive presence of haplogroup J lineages in the South (<italic>P</italic>=0.039) and haplogroup L lineages in the North (<italic>P</italic>=0.029). These results point to geographical genetic differentiation on La Gomera before the European conquest, although we cannot exclude that these differences could be related to small sample sizes or temporal differences during pre-Hispanic times.</p></sec><sec><title>Extant mtDNA structure</title><p>Although comparatively low, the present-day gene diversity on La Gomera (78.21±1.97%) is significantly higher than that of the aborigines (<xref rid="tbl2" ref-type="table">Table 2</xref>). Moreover, the presence of European, sub-Saharan African and Amerindian new lineages testify to the impact of the European colonization despite the autochthonous U6b1a haplogroup (44%) remaining dominant. (<xref rid="tbl2" ref-type="table">Table 2</xref>; <xref ref-type="supplementary-material" rid="sup1">Supplementary Table S5</xref>). AMOVA analysis showed that about 2% of the variance is due to significant (<italic>P</italic>=0.002) differences among municipalities. In particular, Alajeró was characterized by the highest frequencies for H/HV/R (<italic>P</italic><0.0001), T2c1 (<italic>P</italic>=0.0006) and U6c1 (<italic>P</italic>=0.0026) haplogroups and Agulo by those of L3e (<italic>P</italic>=0.001) and U6a (<italic>P</italic>=0.0044). T2b was particularly abundant (<italic>P</italic><0.0001) in Hermigua, haplogroup K1b1a was detected only in San Sebastián (<italic>P</italic>=0.0456), while L3d (<italic>P</italic>=0.0033), T1 (<italic>P</italic>=0.0047) and W (<italic>P</italic>=0.0012) were more frequent in Valle Gran Rey. Furthermore, Vallehermoso and Agulo harboured the highest frequencies of haplogroup J (<italic>P</italic>=0.0027) and Alajeró and Valle Gran Rey those of haplogroup I (<italic>P</italic>=0.022). It should be noted that the Canary indigenous founder lineages<sup><xref ref-type="bibr" rid="bib16">16</xref>, <xref ref-type="bibr" rid="bib17">17</xref>, <xref ref-type="bibr" rid="bib18">18</xref></sup> T2c1, U6a and U6c1 were found in the extant population of La Gomera but are absent in the aboriginal sample. This could be the result of Canary Islanders moving to the island during and after the conquest; however, historical records speak of greater movement of aborigines from La Gomera to Tenerife.<sup><xref ref-type="bibr" rid="bib35">35</xref></sup> Excluding L lineages already present in the aboriginal sample, the total sub-Saharan African contribution to La Gomera's population, most probably due to the postconquest slave trade, was only moderate (6.5%).</p></sec><sec><title>Temporal discontinuity</title><p>Although a high aboriginal input was observed, it has evolved under the influence of the conquest and the strong migratory European input. The Canarian U6b1a haplogroup has dropped from 61–71% in pre-Hispanic times to 40–50% in the present-day La Gomera population (<italic>P</italic>=0.0047). Haplogroup X is another example of decline through time as it was relatively abundant in the indigenous population (11–4%) but is now barely present (0.25%) on the island (<italic>P</italic>=0.0007). Some haplogroups not detected in some areas before the conquest are now especially abundant. For example, haplogroup J now has a frequency of 12.5% in the North of the island, but it was not detected in the northern aboriginal sample (<italic>P</italic>=0.033). On the contrary, haplogroup L3d was significantly more abundant in the North before the conquest than it is in the current population (<italic>P</italic>=0.0125). Pair-wise distances comparing the aboriginal and extant samples show that the southern aboriginal sample was strongly differentiated from the northern and from all present-day samples. In contrast, the northern pre-Hispanic population was comparatively more similar to the extant Gomeran samples, paradoxically showing its closest affinity with the southern municipality of Alajeró (<xref ref-type="supplementary-material" rid="sup1">Supplementary Table S4</xref>).</p></sec></sec><sec><title>Discussion</title><sec><title>Aboriginal inter-insular differences</title><p>Gene diversity (55.9±7.8%) in aborigines from La Gomera (known as Gomeros) was significantly lower than those previously found for the indigenous Canary Island people in general. Specifically, aborigines from Tenerife (known as Guanches) and from La Palma (known as Benahoaritas) showed diversity values within the range of current insular populations (77.5±6.1%<sup><xref ref-type="bibr" rid="bib17">17</xref></sup> and 67.6±9.3%,<sup><xref ref-type="bibr" rid="bib18">18</xref></sup> respectively). Compared with the other islands, these data point to a stronger founder effect during the aboriginal colonization of La Gomera and/or a greater subsequent isolation. The most striking differences observed between islands are the high frequency of the autochthonous haplogroup U6b1a in Gomeros (around 65%) compared with Guanches (11%) and Benahoaritas (7%) and the low frequency of haplogroup H (around 8%) in La Gomera compared with the other two aboriginal populations (44 and 57%, respectively). The lack of the founder haplogroup T2c1 in Gomeros and its frequency in Guanches (14%) and Benahoaritas (10%) is also outstanding. Gomeros also lack L2 lineages, which are present in both Guanches (8%) and Benahoaritas (3%). Particular similarities of aborigines from La Gomera with those of La Palma are the exclusive sharing of haplogroups X and L1b (<xref rid="tbl2" ref-type="table">Table 2</xref>), and with Tenerife the sharing of L3d haplotypes (not found in La Palma) (<xref rid="tbl2" ref-type="table">Table 2</xref>). However, at least some of these differences could be attributed to small sample sizes. In general, the sample of southern Gomeros showed comparatively fewer differences with Guanches and Benahoaritas than the northern Gomeros. Moreover, Guanches were more similar to the present-day Gomeran population than were Benahoaritas (<xref ref-type="supplementary-material" rid="sup1">Supplementary Table S6</xref>). This would be in agreement with archaeological findings relating La Gomera and Tenerife aboriginal cultures.</p><p>It has been estimated that the potential founder lineages such as U6b1a or H1-16260 were more ancient than the oldest archaeological site in the Canary Islands, dated at the first millennium BC.<sup><xref ref-type="bibr" rid="bib18">18</xref>, <xref ref-type="bibr" rid="bib36">36</xref></sup> To reconcile these discrepancies, it was suggested that more than one haplotype per founder haplogroup might have arrived in the Canary Islands with the aboriginal colonization.<sup><xref ref-type="bibr" rid="bib37">37</xref></sup> The presence in Gomeros of the autochthonous U6b1a-derived haplotypes 048 163 172 219 311 and 092 163 172 219 311, in addition to the basal 163 172 219 311 (<xref rid="tbl1" ref-type="table">Table 1</xref>), would support the idea that these derived lineages did not mutate in the Canary Islands but arrived there from North Africa with the aboriginal colonization. However, this hypothesis should be reviewed if older archaeological remains are discovered in the islands.</p></sec><sec><title>Singularity of the extant population of La Gomera</title><p>It has been previously stated that the extant population of La Gomera was genetically differentiated from other islands of the archipelago.<sup><xref ref-type="bibr" rid="bib15">15</xref>, <xref ref-type="bibr" rid="bib16">16</xref></sup> This difference was attributed to a better preservation of the maternal aboriginal substrate, although the effect of genetic drift could not then be ruled out. Now, we know that the comparatively high presence of the autochthonous haplogroup U6b1a in the current population of La Gomera has been inherited from the aboriginal people and was not caused by later genetic drift.</p><p>The subdivision of the total Gomeran population into municipalities allows refined comparisons with other islands. Tenerife is the population with the lowest genetic distance from La Gomera, the municipalities Agulo, Hermigua and Valle Gran Rey being the closest (<xref ref-type="supplementary-material" rid="sup1">Supplementary Table S4</xref>). This result is congruent with the geographical proximity of La Gomera to Tenerife (<xref ref-type="fig" rid="fig1">Figure 1</xref>). When all the islands are taken into account, the first component of PCA analysis (accounting for 17.2% of the variability) shows that the Gomeran municipalities and all the indigenous population are clustered to the left, whereas the other Canary Islands samples, including the eighteenth century population of Tenerife, are clustered to the right (<xref ref-type="fig" rid="fig2">Figure 2a</xref>). Congruently, San Sebastián, the main port and capital of La Gomera and therefore the most affected by external gene flow, is the closest to the right cluster. The main haplogroups responsible for the separation of the two clusters are the European U5b and H to the right and the Canarian autochthonous U6b1a to the left. It is clear that the aboriginal samples of Tenerife and La Palma are situated in the left cluster due to the strong indigenous component of the extant and prehistoric samples from La Gomera. The second component (12.8%) further separates San Sebastián and, to a lesser degree, Gran Canaria and Tenerife from the other populations, through their comparatively higher frequency of U5b2, L2a and K1b1a lineages. The MDS plot based on <italic>D</italic><sub>est</sub> distance values (<xref ref-type="fig" rid="fig2">Figure 2b</xref>) indicates that all the modern municipalities of La Gomera and the northern aboriginal samples are similar to each other and different from the cluster conformed by the rest of the archipelago, including the aboriginal samples from La Palma and Tenerife. In this case, the southern aboriginal sample from La Gomera behaves as an outlier of the Gomeran cluster, probably due to its higher frequency of U6b1a (~71%).</p><p>After the first analysis of the aboriginal samples,<sup><xref ref-type="bibr" rid="bib17">17</xref></sup> admixture estimates of the current population became calculable using the aboriginal sample as one of the parental contributors (Iberians and West sub-Saharan Africans being the others), instead of inferring them from North African Berber populations as before.<sup><xref ref-type="bibr" rid="bib16">16</xref>, <xref ref-type="bibr" rid="bib38">38</xref></sup> Mean estimates pointed to the Iberian Peninsula as the main contributor to the Canarian maternal gene pool with 55%, followed by 42% of aboriginal influence and a minimal sub-Saharan African input of around 3%.<sup><xref ref-type="bibr" rid="bib17">17</xref></sup> Repeating calculations for the whole population of La Gomera using Gomeros as indigenous parental population, we obtained percentages of 55.4, 37.8 and 6.8% for the aboriginal, Iberian and sub-Saharan African components, respectively, in this case the aboriginal substrate being the largest. Taking into account the different municipalities, this indigenous contribution ranges from 62.4% in Alajeró to 48.1% in San Sebastián (<xref ref-type="supplementary-material" rid="sup1">Supplementary Table S7</xref>). The Sub-Saharan input due to postconquest slavery varies from 0.0% in Alajeró to 15.6% in Agulo.</p><p>The comparison of mtDNA and Y-chromosome data from the current Canary Islands population<sup><xref ref-type="bibr" rid="bib16">16</xref>, <xref ref-type="bibr" rid="bib38">38</xref></sup> led to the detection of a significantly higher contribution of aboriginal matrilineages compared with patrilineages. This result is usually explained by the asymmetrical migration of European colonizers, which principally consisted of males. The reduction in the male aboriginal gene pool can also be explained both by their higher mortality rate during the conquest and their lower socioeconomic status afterwards.<sup><xref ref-type="bibr" rid="bib20">20</xref></sup> The case of La Gomera in particular, with the highest (around 50%) aboriginal maternal contribution, (Santos <italic>et al</italic>,<sup><xref ref-type="bibr" rid="bib15">15</xref></sup> Rando <italic>et al</italic><sup><xref ref-type="bibr" rid="bib16">16</xref></sup> and this study) and one of the lowest (around 6%) aboriginal paternal contributions<sup><xref ref-type="bibr" rid="bib19">19</xref></sup> may indeed reflect the particularly brutal way this island was finally conquered, producing the strongest sexual asymmetry in the Archipelago.<sup><xref ref-type="bibr" rid="bib3">3</xref></sup> Alternatively, strong genetic drift could also be the main cause of this striking sexual asymmetry.<sup><xref ref-type="bibr" rid="bib19">19</xref></sup> Unfortunately, the low nuclear DNA yield of the Gomero sample prevented a direct analysis of its Y-chromosome profile. However, taking into account the aboriginal contribution estimated from autosomal data (43%)<sup><xref ref-type="bibr" rid="bib14">14</xref></sup> and the indigenous maternal contribution (55.2%) obtained here, applying the formula: mAUTO=1/2 m mtDNA+1/2 m NRY<sup><xref ref-type="bibr" rid="bib39">39</xref></sup> provides a theoretical aboriginal Y-chromosome ancestry of about 31%. This value is at least twice that obtained using current North African Berbers as parental population.<sup><xref ref-type="bibr" rid="bib40">40</xref></sup> As higher male mortality and asymmetrical mating would especially occur at the beginning of the colonization, we conclude that male extermination could have been less drastic than suggested and that male gene drift also had an important role.</p></sec></sec><sec><title>Conclusion</title><p>Ancient mtDNA results from La Gomera samples are congruent with the phylogeographic pattern observed in the current population and with archaeological evidence. The high diversities and close affinities found previously for the aboriginal samples from Tenerife<sup><xref ref-type="bibr" rid="bib17">17</xref></sup> and La Palma<sup><xref ref-type="bibr" rid="bib18">18</xref></sup> better fit an island model of aboriginal colonization, with several arrivals and/or frequent migration between islands.<sup><xref ref-type="bibr" rid="bib18">18</xref></sup> In contrast, the low diversity, strong intra-insular microdifferentiation and high inter-insular heterogeneity found in the aboriginal samples from La Gomera appears to reflect a single colonization process, with a strong founder event and subsequent isolation. This idea is strongly reinforced by the absence in the aboriginal Gomeran samples of the founder lineages T2c1 and U6c1, proposed markers of a secondary pre-Hispanic colonization elsewhere in the islands.<sup><xref ref-type="bibr" rid="bib15">15</xref></sup> The abrupt topography of the island must also have promoted isolated settlements of the Spanish colonizers in historical times that, after mixing with the local aborigines, kept relatively segregated until recent times. This would also contribute to the strong genetic structure found in La Gomera. In conclusion, this small island is not only particularly rich in endemic flora and fauna but is also where the pre-Hispanic aboriginal substrate is best preserved in the Canary archipelago.</p></sec></body><back><ack><p>This research would have not been possible without the enthusiastic collaboration of the anonymous donors from La Gomera and the support of the staff from Área de Salud de La Gomera (Centro Canario de Salud) and IES San Sebastián de La Gomera.
