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
Pacific blue-eye are black markings at the base of the anterior rays of the anal and rear dorsal fins, and the front (anterior edge) is sometimes white and the rear (posterior) edge greyish in colour. The male's fins may turn orange during breeding season. Preserved specimens generally discolour to yellow or tan. The Pacific blue-eye can be distinguished from the highly invasive and noxious introduced eastern mosquitofish ("Gambusia holbrooki") by its forked tail fin. The Pacific blue-eye is found from Narooma in southern New South Wales north to the Rocky River in Cape York, though it is uncommon in eastern Cape York.
