How do you know a living creature hasn't evolved without being able to do DNA testing? Unless the organism is extant or only died out in the last few thousand years and organic material remains, your statement about stopping and starting evolution is hard to support. And what sort of time frame are you going to measure the difference between starting and stopping and just slow evolutionary change?
http://news.mongabay.com/2007/0218-birds.html You are making claims here that I don't think can be supported unless you can produce DNA evidence showing the most ancient orca is genetically identical to the most recent. When did the orca reach its comfort zone and why is it suspected there are 3 species of Orca?

A restatement of Punctuated Equilibrium. It also doesn't address the problem of knowing what drove a round of evolution. Even if the meteor strike did happen 63 million years ago and killed off the dinosaurs, does that say anything that can be proven about the evolution of mammals? |

I wonder where the Venus fly Trap fits into this discussion. Does it have a symbiotic relationship with the bugs that live in it's habitat? |

I'd say it was more predatory than symbiotic. Do you consider our relationship to cows to be symbiotic? |

Nope, but it does say a lot about the adapatability and evolutionary variability of dinosaurs. |

Never seen the Vorlons, but I have heard a Vogon reading the universe's worst poetry! |

I agree. A 160 million year run ain't too bad! Wonder if mammals make it that long. |
