Genetic Link Between Etruscans and Anatolia?

The dating seems strange - can't make it out. As far as I can tell KYA means "thousand(s) years ago." If this is correct, then the article is saying the genetic linkage between Anatolia and the Etruscans was first made between 2,300 years ago (plus or minus 400 years?) and 1,100 years (plus or minus 100 years?) History tells us that the Etruscans first became an identifiable civilization in Italy about 900-800 BCE (2,900 to 2,800 years ago). That would put the oldest date from the article (2,300 plus 400 years, or 2,700 BCE) near this date range: Abstract from the European Journal of Human Genetics Short Report 3 December 2008; doi: 10.1038/ejhg.2008.224 The Etruscan timeline: a recent Anatolian connection Francesca Brisighelli1,2, Cristian Capelli3, Vanesa Álvarez-Iglesias1, Valerio Onofri4, Giorgio Paoli5, Sergio Tofanelli5, Ángel Carracedo1,6, Vincenzo L Pascali2 and Antonio Salas1 1Unidade de Xenética, Facultade de Medicina, Instituto de Medicina Legal, Universidade de Santiago de Compostela, Galicia, Spain 2Forensic Genetics Laboratory, Institute of Legal Medicine, Università Cattolica del Sacro Cuore, Rome, Italy 3Department of Zoology, University of Oxford, Oxford, UK 4Institute of Legal Medicine, Universita' Politecnica delle Marche, Policlinico Torrette, Ancona, Italy 5Department of Biology, University of Pisa, Pisa, Italy 6Fundación Pública Galega de Medicina Xenómica (FPGMX-SERGAS), CIBER enfermedades raras, Santiago de Compostela, Galicia, Spain Correspondence: Dr A Salas, Unidade de Xenética, Facultad de Medicina, Instituto de Medicina Legal, Universidad de Santiago de Compostela, 15782, Galicia, Spain.

The origin of the Etruscans (the present day Tuscany, Italy), one of the most enigmatic non-Indo-European civilizations, is under intense controversy. We found novel genetic evidences on the mitochondrial DNA (mtDNA) establishing a genetic link between Anatolia and the ancient Etruria. By way of complete mtDNA genome sequencing of a novel autochthonous Tuscan branch of haplogroup U7 (namely U7a2a), we have estimated an historical time frame for the arrival of Anatolian lineages to Tuscany ranging from 1.10.1 to 2.30.4 kya B.P. (emphasis added) Short of paying $32 to download the current issue online, I guess I'll remain in the dark as to whether the authors are suggesting that ALL Etruscans can be traced back to Anatolia through this mitochondrial DNA or whether only a certain portion of Etruscans can be traced back to Anatolia through this DNA tag inherited from one's mother!
