Enigmatic structures on the Russian Plains are a rare example of Palaeolithic hunter-gatherers living on in the extreme Ice-Age environment some 23-18,000 years ago. What might have brought ancient hunter gatherers to this site? One possibility, says said Dr Alexander Pryor, a Paleolithic archaeologist at the University of Exeter, is that the mammoths and humans could have come to the area on masse because it had a natural spring that would have provided unfrozen liquid water throughout the winter – rare in this period of extreme cold.

Scientists have calculated that for a period lasting one million years and beginning 1.2 million years ago, at a time when our ancestors were spreading through Africa, Europe and Asia, there were probably between 18,500 to 26,000 individuals capable of breeding (and no more than 26,000). The actual population would have been about three times as large, or 55,500. This made them an endangered species with a smaller population than today’s species such as gorillas which number 25,000 breeding individuals and chimpanzees (21,000).
