Two teeth coming from fossil human skeletons were examined in the Molecular Technology Institute of Forensic Medicine Department, Wroclaw Medical University. It was stated that both teeth came from two men on the basis of the gene of amelogenin variants study. Determining polymorphisms of SNP type from chromosome Y resulted in categorizing skeleton from grave no. 1 with very high probability into haplogroup G, whereas skeleton from grave no. 2 with very high probability into one of three haplogroups J, I or E*.Table 2:
It's not clear to me how skeleton 2 is attributed to J or I or E* on the basis of these SNPs. If anyone can figure it out, post in the comments.

Assessment of late Neolithic pastoralist's life conditions from the Wroclaw-Jagodno site (SW Poland) on the basis of physiological stress markers
Bohdan Gworys et al.
So-called physiological stress markers are extremely valuable in assessing life conditions of old human populations. They constitute effects of adverse environmental conditions, which leave traces on skeleton. Those traces allow for partial assessment of life conditions not only in environmental and social but also cultural aspects for prehistoric populations. The aim of this study is to estimate the influence of general environmental conditions on human organism at the final stage of the Neolithic period – in the Corded Ware culture. Two skeletons discovered in a tumulus on the outskirts of Wroclaw in the Jagodno district have been subjected to assessment. Their age at the moment of death has been determined in both cases on the basis of multi-feature analysis of changes occurring in formation of particular morphologic features of skeleton and teeth. Attention has been paid to the obliteration degree of skull sutures and the surface state of chewing tooth crowns. A comprehensive DNA analysis has been conducted determining sex of the remains. Also bacteriological analysis of the research material has been conducted. Measurements of all available metric features of the skeletons have been performed with the use of the Martin method. Inventory and basic description of the finds accompanying skeleton remains have been carried out as well. Intensity of the following physiological stress markers have been defined and evaluated: Harris lines; cribra orbitalia; cribra cranii. Skull morphology, degree of suture obliteration, surface state of chewing tooth crowns and estimation of degree of bone development of postcranial skeleton indicate that both skeletons detailed age was about 16 – 18 years. Harris lines on the femur were formed in the 2nd and the 3rd year of life and on both tibias – in the 2nd year of life. Obtained results indicate that those people were expose to stress connected with food deficit when they were very young. Poor porotic changes on the skull and isotopic data suggest that their life quality increased at later age.
