Prehistory of Siberia Siberia were hunter-gatherers, whose prey consisted of mammoths and reindeer, and occasionally fish as well. In the 6th millennium BC, pottery spread across the whole of Siberia, which scholars treat as the beginning of the Siberian neolithic. Unlike Europe and the Near East, this event did not mark a major change in lifestyle, economy or culture. The prehistoric inhabitants of the vast areas of taiga and tundra east of the Yenissei and north of Baikal differ in many ways from the prehistoric cultures of the other parts of north Asia. There is stronger evidence than usual for settlement continuity here
Body water ocular fluids. Adipose tissue contains about 10% of water, while muscle tissue contains about 75%. In "Netter's Atlas of Human Physiology", body water is broken down into the following "compartments:" Total body water can be determined using Flowing afterglow mass spectrometry measurement of deuterium abundance in breath samples from individuals. A known dose of deuterated water (Heavy water, DO) is ingested and allowed to equilibrate within the body water. The FA-MS instrument then measures the deuterium-to-hydrogen (D:H) ratio in the exhaled breath water vapour. The total body water is then accurately measured from the increase in breath deuterium content in
