Birds do not have teeth. And if a fossil of a "bird" with teeth were ever discovered, it would be classified as a transitional fossil. Yet, ironically, scientists are able to manipulate the genes of a chicken, so that it grows teeth - something chickens had earlier in their evolutionary progress. (have seen the photos?) http://images.livescience.com/images/060222_chicken_teeth_02.jpg
It also convinces me that...
For an animal to mutate back to a previous state does not require slow and gradual evolution, but rather, can happen in one generation. So for a person to be born with 8 limbs (like a spider), or sprout wings (like a bird) is no longer science fiction.

If a person was born with wings or eight limbs, they would not be reverting to a previous state, as we do not have ancestors with eight limbs or wings. The girl who recently had surgery to remove extra limbs did not have them because of a mutation, she had them because she had started off with a twin, four of those limbs belonged to the twin that did not develop.
It is possible for an animal to be born with something that its ancestors had but has been lost. Humans can be born with tails, or whales and dolphins can be born with hind limbs. It's called an atavism. The scientists made it happen to the chicken.

There is no difference between a natural mutation which causes a given effect and creating that same sequence in the genome. The genome is a set of blueprints, whether a man gets in there and modifiys the blue prints, or nature changes them--makes no difference.

Please provide me with a complete picture of you growing up from the day 1 until now with absolutely no gap!
Picture you took yearly won't do because there is a gap between the two and you can't prove to me that you have grown in between.
Do you think this kind of demand is reasonable to you?
Evolution provides us with the most complete simple and elegant picture of origin of different species. It requires least presumptions ( no preposturous assumptions like God or "vital force" ), and it has the largest explanatory power.

Have you ever looked at a Goose. It clearly has the remanants of a tooth like structure in its beak. The edges of its beak are very slightly serated.

All mutations occur thus. It is only those animals born with mutations that are advantageous service and pass those genes along.

Interestingly it took educated scientist (intelligent design) to get the chicken to grow teeth. Nice try. Try again.

Evolution is a fallacy created by men to explain what needs no explanation.
