Όπως αναφέρει η ιστοσελίδα ....
nature.com η λίμνη, η οποία είναι επισήμως γνωστή με την ονομασία Ρούπκουντ (Roopkund), βρίσκεται σε υψόμετρο πέντε χιλιομέτρων και αποτελεί «σπίτι» για τα λείψανα εκατοντάδων ανθρώπων.
Έπειτα από έρευνα σε 38 σκελετούς, επιστήμονες ανακάλυψαν ότι οι 14 εξ αυτών ανήκουν σε κατοίκους των ακτών της ανατολικής Μεσόγειου και ταιριάζουν γενετικά με τους σημερινούς πληθυσμούς της ηπειρωτικής Ελλάδας και της Κρήτης.
Οι σκελετοί χρονολογούνται από την περίοδο μεταξύ του 1.600 και 1.900 μ.χ., ωστόσο κανείς δεν μπορεί να εξηγήσει με ασφάλεια το πώς και γιατί βρέθηκαν στη συγκεκριμένη περιοχή. Όπως τονίζεται στην έρευνα, οι 13 από τους 14 σκελετούς ανήκουν σε άτομα που κατά πάσα πιθανότητα κινούνταν μαζί και πέθαναν την ίδια περίοδο, σε αντίθεση με σκελετούς ατόμων από τη νότια Ασία που εικάζεται ότι βρέθηκαν εκεί και πέθαναν σε διαφορετικές χρονικές περιόδους.
Το DNA των 23 άλλων σκελετών ταιριάζει γενετικά με τους σημερινούς κατοίκους χωρών της νότιας Ασίας (Ινδία, Πακιστάν, Αφγανιστάν, Νεπάλ, Μπαγκλαντές) ....... η πρωτότυπη δημοσίευση παρακάτω :
Genetic affinities of the Roopkund subgroups
We used qpWave18,19 to test whether Roopkund_B is consistent with forming a genetic clade with any present-day population (that is, whether it is possible to model the two populations as descending entirely from the same ancestral population with no mixture with other groups since their split). We selected 26 present-day populations for comparison, with particular emphasis on West Eurasian-related groups (we analyzed the West Eurasian-related groups Basque, Crete, Cypriot, Egyptian, English, Estonian, Finnish, French, Georgian, German, Greek, Hungarian, Italian_North, Italian_South, Norwegian, Spanish, Syrian, Ukranian, and the non-West-Eurasian-related groups Brahmin_Tiwari, Chukchi, Han, Karitiana, Mala, Mbuti, Onge, and Papuan). We find that Roopkund_B is consistent with forming a genetic clade only with individuals from present-day Crete. These results by no means imply that the Roopkund_B individuals originated in the island of Crete itself, although they suggest that their recent ancestors or they themselves came from a nearby region (Supplementary Note 5; Supplementary Data 5).
We performed a similar analysis on individuals belonging to the Roopkund_A group and find that they cannot be modeled as deriving from a homogeneous group (Supplementary Note 6). Instead, Roopkund_A individuals vary significantly in their relationship to a diverse set of present-day South Asians, consistent with the heterogeneity evident in PCA (Fig. 2a). We were unable to model the Roopkund_C individual as a genetic clade with any present-day populations, but we were able to model its ancestry as ~82% Malay-related and ~18% Vietnamese-related using qpAdm7, showing that this individual is consistent with being of Southeast Asian origin. We tested if any of the Roopkund groups show specific genetic affinity to present-day groups from the Himalayan region, including four neighboring villages in the northern Ladakh region for which we report new genome-wide sequence data, but we find no such evidence (Supplementary Note 7). Within the Roopkund_A group which has ancestry that falls within the variation of present-day South Asians, we observe a weakly significant difference in the proportion of West Eurasian-related ancestry in males and females (p = 0.015 by a permutation test across individuals; Supplementary Note 8), with systematically lower proportions of West Eurasian-related ancestry in males than females. This suggests that the males and females were drawn from significantly different mixtures of groups within South Asia
