This is a preemptive strike against anyone that is going to argue that we haven't observed any "macro-evolution" (no, I'm not a Bush fan).
Micro and macro evolution are pretty much the same thing. The difference is that one happens over a short period of time and the other is just a combination of a whole bunch of the first one.
Microevolution happens all the time. People observe it on a daily basis. A whole bunch of
microevolution will result in what you would call
macroevolution.
Some people on the board will deny that there is no difference, and I somewhat agree. To use crashfrog's example,
microevolution is like taking a walk to the house next door and
macroevolution is like taking a walk to the next town, the next state, or the next country. It will take you a long long time to get there, but you will eventually get there by walking.
So, no, we haven't seen any iguana growing wings and turn into a bird. Give us another few million years or so and I'll give you some examples of the so-called
macroevolution.
