We found potential evidence of a severe population bottleneck in the cave lion during the previous interstadial, sometime after 48 000 years, adding to evidence from bison, mammoths, horses and brown bears that megafaunal populations underwent major genetic alterations throughout the last interstadial, potentially presaging the processes involved in the subsequent end-Pleistocene mass extinctions.

这些生活在不列颠群岛以及欧洲和北美地区的狮子的生存环境与目前非洲的大型猫科动物完全不同：在更新世，英国是苔原冻土地带，就像现在的俄罗斯草原一样，很多大型动物聚集那里，如哺乳动物、羊毛犀牛、巨型鹿等。13000年前，这些狮子和大型食草动物在大灭绝中消失。

What we need is integration of the data and precepts of everything from molecular biology to the geobiology of mass extinctions and evolutionary rebounds - entities and processes of vastly different spatiotemporal dimensions.

我们需要的是整合数据资料和一切教训，从分子生物学到大灭绝和进化反弹的地理生物学——差异极大的时空尺度中的实体和过程。

While the details are controversial, and it now appears that many of the major divisions within the Mammalia had already evolved well before the K/T event, there can be little doubt that mass extinctions must have a significant influence on the tree of life and the avenues it will take.

尽管其细节上还存在争议，同时现在看起来许多哺乳动物的主要分支在白垩纪灭绝事件之前就已经进化得很好，但，毫无疑问的，大灭绝一定对于生命树及其选择的道路产生了重大的影响。

"We found that over the fossil record as a whole, the higher the temperatures have been, the higher the extinctions have been," said University of York ecologist Peter Mayhew, the co-author of the peer-reviewed research published in the Proceedings of the Royal Society B, a British journal.

不认识！那么英国人在学英语单词的时候需不需要记住单词的汉语意思？

Past extinctions are clustered in geological time (e.g.significant extinction occurred in the permian and Permian and Pleistocene).

过去的灭绝聚集在地质时间中(如二叠纪和更新世出现的重大灭绝)。

Intriguingly, at just this time, a set of extinctions -- known as the Pliocene/Pleistocene extinctions -- is also known to have occurred.
