Call me TED obsessed, but some of these videos are super cool. Stewart Brand, formerly an internet developer, is now backing the biotech industry push for the use of cloning to reintroduce extinct species. While many think that this research is unethical due to the nature of human intervention, Brand argues that human intervention is what caused these species to go extinct in the first place (giving the example of the American Passenger Pigeon). Furthermore, he focuses on reintroducing key species to environments devastated by their loss.
Pulling together many examples of recently extinct animals (whose tissues and DNA have been frozen or preserved), Brand forms a pretty comprehensive study of the entire field. He quotes research being done by several members of a team that he and his wife assembled, all working towards the common goal of de-extinction through biotechnology and cloning.
If you're still not convinced, then check out the footage of the Thylacine (Tasmanian Tiger) at about 3:08. How awesome is that? (I want one)
