In 2007, Australian zoologists from the Australian Center for Ancient DNA at the University of Adelaide wanted to begin DNA analysis of feces collected during the 1950s and 1960s, in the belief that it survived in the wild much longer than previously thought. More ambitious involves outright cloning, which began in 1999 with reconstructing the DNA from preserved tissue samples and a fetus kept in alcohol since 1886<ref>http://www.smh.com.au/news/Science/Clone-again/2005/05/14/1116024405941.html</ref>. | In 2007, Australian zoologists from the Australian Center for Ancient DNA at the University of Adelaide wanted to begin DNA analysis of feces collected during the 1950s and 1960s, in the belief that it survived in the wild much longer than previously thought.
