Polar Bears Come From Britain

Recommended Posts

Polar bears traced back to Britain

Telegraph - Nick Collins

All polar bears originate from a single ancestor which lived in Britain or Ireland about 50,000 years ago, according to DNA study by scientists.

A genetic marker carried by every polar bear alive today proves that they all descend from the same female brown bear, who bred with a polar bear to create hybrid offspring.

It had been assumed that this took place in Alaska 14,000 years ago, but now analysis of 242 brown bear and polar bear DNA samples from the past 120,000 years show the hybridisation of the two species occurred much earlier.

Fossils found in Irish caves show that polar bears in fact began carrying the DNA of the female brown bear between 20,000 and 50,000 years ago, before brown bears disappeared from the British Isles.

So it's not just coincidence they look like over-fed Labradors..

Interesting, so polar and brown bears came into contact with each other during periods of extreme climate and temperature changes, and all without the aid of man and 4x4's :rolleyes:

If you believe the last ice age occured are you no longer a climate change 'denier' or is that just a term for people who think the earths temperature is a flatline?

What does that mean in English?

The last ice age ended around 10k years ago, the warming wasnt caused by mans discovery of fire btw :lol:
