So this is from a time when the early humans living here are coming out of the sort of Mediterranean weather they've been having and they starting to face colder winters? Yeah. That's right. Must be very frightening for them. It would have been a challenge for them to cope with because these people of course did not have what we called cultural buffering, so we don't think they had sophisticated dwellings. We don't even know if they had fire to help them in the cold. There's no evidence of fire in Britain this far back. So these people were exposed to the elements in a much more severe way than we ever are. That's present day. But the real question remains. Many human-like species have populated Britain in the last 700,000 years. How have they coped with ice ages? And 600,000, and here we are at 700,000. So this first line is the level we've been digging at today? That's right. 在这个松球所在的时期,早期人类习惯的地中海温暖气候逐渐过去,人类开始面对寒冷天气 ,对吗? -对 -他们肯定很恐慌,对他们确实是个很大的挑战, 当时的人们显然并未缓冲,而是直接面对转变。我们认为,他们也没有复杂的建筑,也不一定懂得生火御寒。没有证据能证明那时的英国有火,所以这些人直面恶劣天气没有任何防护措施。这是现在,真正的问题仍未解答。过去的70万年间,许多类人物种都生活在英国,他们是怎样度过冰河期的呢? 六十万年,这是七十万年,第一条线代表我们正在挖掘的时期 是的
