Does anyone have ancient samples from Cyprus?

[Diocles]

Some are listed in the datasheet from David Reich's Lab and I wondered if the coordinates were available

[AimSmall]

Do you have a list of the sample IDs?

This is what I show for non-Modern from Reich...

Code:

I4208    3500-3400 BCE
I4207    8300-7000 BCE
I4209    8300-7000 BCE
I4210    8300-7000 BCE

I don't find these samples in any of my G25 libraries.  My guess is they might have issues such as coverage or contamination.  Would have to review the anno file again to know.

So I have these from a Reich dataset that had K36 ran against the whole thing.  It then was ran through G25 simulation to get these sims.  I don't believe they are the ancient samples listed above however.

Yep, same ones

I updated my post above

[Capitalis]

Code:

I4208    3500-3400 BCE
I4207    8300-7000 BCE
I4209    8300-7000 BCE
I4210    8300-7000 BCE

I don't find these samples in any of my G25 libraries.  My guess is they might have issues such as coverage or contamination.  Would have to review the anno file again to know.

Coverage for all four samples is between 0.03x and 0.05x, so you are correct they are too low coverage for G25 meaning we would get spurious results if we used them. Bad luck to the OP.

Looks like we've got some news

Palaeogenomic insights into the origins of early settlers on the island of Cyprus

Archaeological evidence supports sporadic seafaring visits to the Eastern Mediterranean island of Cyprus by Epipaleolithic hunter-gatherers over 12,000 years ago, followed by permanent settlements during the early Neolithic. The geographical origins of these early seafarers have so far remained elusive. By systematically analysing all available genomes from the late Pleistocene to early Holocene Near East (c. 14,000–7000 cal BCE), we provide a comprehensive overview of the genetic landscape of the early Neolithic Fertile Crescent and Anatolia and infer the likely origins of three recently published genomes from Kissonerga-Mylouthkia (Cypriot Late Pre-Pottery Neolithic B, c. 7600–6800 cal BCE). These appear to derive roughly 80% of their ancestry from Aceramic Neolithic Central Anatolians residing in or near the Konya plain, and the remainder from a genetically basal Levantine population. Based on genome-wide weighted ancestry covariance analysis, we infer that this admixture event took place roughly between 14,000 and 10,000 BCE, coinciding with the transition from the Cypriot late Epipaleolithic to the Pre-Pottery Neolithic A (PPNA). Additionally, we identify strong genetic affinities between the examined Cypro-LPPNB individuals and later northwestern Anatolians and the earliest European Neolithic farmers. Our results inform archaeological evidence on prehistoric demographic processes in the Eastern Mediterranean, providing important insights into early seafaring, maritime connections, and insular settlement.
