Glazkov Tunguses had copper knives, bronze fishing hooks, and ceramics. Glazkov burials brought new funeral traditions, the deceased are oriented down river, instead of geographical direction, crouched position, and intentionally broken artifacts, likely to protect the living from the danger presented by a deceased. The end of the Glazkov time in the southern portion of Baikal eastern area is brought by influx of people from the Tuva and north-western Mongolia, who brought a distinctive tradition of stone kurgans with fences ("chereksurs"), which resulted in a formation in the Central Asian steppes of a "Slab Grave Culture" that became an eastern wing of a huge nomadic world in Eurasia, which produced in the beginning of the 1st millennium BCE a bright civilization known as Scythian-Siberian World. Glazkov culture had clearly expressed variations, bringing about a number of hypotheses about ethno-cultural situation in the Baikal area, all of them concurring that all population groups are of the animal husbandry type. These cultures are "Daur", "Slab Grave Culture", and "Palace Type" burials, seen by some researchers as the earliest predecessor of the Slab Grave Culture   Hunting, fishery and gathering. All 4 tested Early Bronze Age individuals from the Ust-Ida burial site belonged to the Y-DNA haplogroup Q-YP4004 under Q1a2, common among modern Native Americans, Kets, and some Turkic (but not Tungusic) peoples. Two earlier Late Neolithic burials from the same area yielded Y-haplogroups Q1a2 and N1c1.
