(单词翻译:双击或拖选)
The male flicks1 the air with his tongue to test if the ewe will accept him. The next stage of courtship is not so subtle. He gives her a kick. At this highly-charged time of year, skirmishes can easily erupt between the rams2, especially if they both have the same ewe in their sights.
But though there was food in Beringia, it was still cold, bitterly cold. The much of the year, temperatures would have remained below freezing 24 hours a day. How did the ice age animal survive in such a harsh world?
The more hair, the better for a start. Mask oxen can stay warm in temperatures of minus 50 degree centigrade, thanks to their chill-proof woolly coats. In fact, they have the warmest fur of any mammal. They have an extremely long outer layer over another very dense3 fine wool layer beneath, a combination so effective that even in winter, the mask ox can overheat if it runs too far. From frozen mammoths’ remains4, we know they had a very similar fur coat, made up of strands5 of hair up to a meter long.
