"I can give you several examples of new species that have emerged within human observation. The best example that I can give you is the butterfly, the genus of butterfly known as Hedylypta. Hedylypta is a genus of butterfly that feeds on various plants. It's endemic to the Hawaiian Islands, which means it's only found there. And there turn out to be two species of Hedylypta with mouthparts that only allow them -- only allow them to feed on bananas. Now why is that significant? It is significant because bananas are not native to the Hawaiian Islands. They were introduced about 1,000 years ago by the Polynesians -- we know this from the written records of the Hawaiian Kingdom -- and what that means is that by mutation and natural selection, these two species have emerged on the Hawaiian Islands within the last 1,000 years. And I think that's a very good case in point." Ken Miller in "Resolved: That evolutionists should acknowledge creation" _Firing Line_, 4 December 1997, p. 24.
