  23. Here's the latest on molecular biology / biotechnology advances and our furry friend, the Woolly Mammoth. Unlike most dinosaur fossils, Woolly Mammoth remains are often found in frozen, less-deteriorated states in Siberia; and often contain viable proteins such as collagen, from which genetic sequences can be produced. In ice condition: Amazingly preserved woolly mammoth found frozen in Siberia after 39,000 YEARS goes on display in Tokyo http://www.dailymail.co.uk/sciencetech/article-2358695/Woolly-mammoth-frozen-Siberia-39-000-YEARS-goes-display-Tokyo-woolly.html Woolly mammoth discovery raises exciting possibilities http://www.cbc.ca/news/technology/woolly-mammoth-discovery-raises-exciting-possibilities-1.1386398 The quest is to clone a mammoth.
