This paper deals with the identification and comparison of dietary practices and their changes from the Late Neolithic to the Late Bronze Age in two different ecosystems – the lower reaches of the Daugava river and Lake Lubāns wetland. Zooarchaeological, palaeobotanical, and stable isotope evidence of chemical elements were used. The obtained results show that the beginning of early farming in Latvia can be observed in the late Neolithic period, especially for the Corded Ware Culture people. However, the consumption of freshwater fish also remains significant during this period. Farming, as the main form of food provision, became established in Latvia in the Middle Bronze Age.

Abstract
This article presents a review on population genetics of Latvians, which alongside Lithuanians are the two extant Baltic speaking populations. The article provides a description of genome-wide single nucleotide polymorphism (SNP) data and contains a comparative analysis of the results of studies performed on classical autosomal genetic markers, mitochondrial DNA (mtDNA) and the non-recombining part of the Y chromosome (NRY), with data on neighbouring populations. The study also covers data of recently performed ancient DNA (aDNA) studies carried out on samples from the territory of today's Latvia. The results of population genetic studies have shown a mixture of eastern and western genetic traits in present-day Latvians with only small differences between Latvian subpopulations. Studies of the Baltic "tribal gene" LW

, as well as the gene's SERPINA1 allele PIZ have indicated the presence of a considerable Baltic admixture in the neighbouring Finno-Ugric and Slavic populations. Although mtDNA analyses have shown that Latvians genetically in general belong to the same common gene pool as most of the Europeans, the Y-chromosomal lineage composition suggests that they are most similar to Northern and Eastern European populations of Lithuanians, Estonians, and Eastern-Slavic populations, which are ethnogenetically closest to them. The analysis of aDNA from the Early and Middle Neolithic did not present any genomic evidence of gene-flow from Central European farmers or any mitochondrial or Y-chromosomal haplogroups that are typical for them in the hunter-gatherers from the territory of today's Latvia and Lithuania.
