How did mammoths survive the extreme cold ?

For the first time scientists have recreated a blood protein that could explain how mammoths survived the ice age.
The feat represents a breakthrough as it is the first time that proteins from a long extinct animal have been recreated. Mammoths died out around 3500 years ago but were highly adapted to survive in the bitter cold of the last ice age.
Canadian scientists have resurrected haemoglobin of woolly mammoth - a blood protein that may explain how the animals coped with the cold of an ice age. It is the first time that proteins from a long-dead organism have been recreated in a living cell.

Thanks B??? Um...... Mammoths could survive the cold because they had fur covering them. Like the Muskox that could protect them from the cold.

I've found this article which is very similar.. Mammoths 'developed anti-freeze blood' http://www.telegraph.co.uk/earth/wildlife/7668272/Mammoths-developed-anti-freeze-blood.html

Interesting article, perhaps some of us will be able to survive the next ice age with the new hemoglobin.

Apparently it wasn't enough to save them (even from the cold).

I read this yesterday in our local paper. This research is going on just up the street from me! I work on the University of Manitoba campus but not for the University. I'm with Agriculture Canada doing DNA sequencing. Nothing nearly as exciting as this!

Yes, exicting to saay the least..E coli though seems to be used in a looot of testing, hell I just used it in our micro lab..always enough of good e coli laughs well I'll be wanting to know more!

Polar Bears live in extreme cold conditions. I wonder if they have a similar structure in their cells? I would have thought the fur would be sufficient for both species... Well, maybe not sufficient enough for the mammoths.
