Quite a week for paleontology. First a mammoth with intact blood is found (seemingly raising the odds of cloning, even though that's still some years off at best). (Some people caution that, while this appears in many news services, it may trace back to Pravda, which has gone from being predictably false under the Soviet regime to being unpredictably crazy at times.) Then the "first bird," 150MY-old Archeopteryx, was restored to its proper place in the dino-to-bird evolutionary chain thorough comparing characteristics with an even older fossil, a newly described bird from China dating 10MY earlier.
When convergent evolution is a well known fact, there is the possibility that mammoths may re-evolve during the next glacial.
