DNA studies on mammoth remains have shown that their blood was able to carry oxygen much more efficiently at low temperatures than present day elephants. Mammoths had 'anti-freeze' blood May 2, 2010: news.bbc.co.uk/go/pr/fr/-/2/hi/science/nature/8657464.stm Stalactites and stalagmites form slowly in layers over thousands of years in caves. If there is even a trace of uranium in them the age of the different layers can be determined. and by studying the oxygen isotopes in the calcium carbonate, it can be determined whether they formed when the climate was dry or wet.
