Reindeer associations

Alice Roberts ponders the prehistory of people and reindeer: "Rudolph and our early ancestors a love story".

The end of the ice age saw a massive global extinction: many large mammals fell prey to changing climate and the effect of some rather formidable hunters sharing their landscape. There was a decline in the genetic diversity of reindeer after the peak of the last ice age 20,000 years ago probably due to a warming climate as well as those palaeolithic hunters but reindeer survived, and thankfully they don't look likely to become extinct any time soon.
