You still don't understand the word "theory". Please read here, particularly #1 & #3: http://dictionary.reference.com/browse/theory
Then you should read up on macro evolution here, particularly the 2nd bulletted item: http://en.wikipedia.org/wiki/Macroevolution
The answer to your question is this: You have some misconceptions. Please do yourself a favor and read up on the issues you are talking about.

Your Right. Macro evolution is a theory. A scientific Theory.
Your Wrong. Gravity is a theory. A Scientific Theory.
IF someone is born with 11 fingers ( more likely 12 ) then yes his/her offspring IS indeed more likely to be born with 11 fingers.
Are you different from your parents? Are your children different than you? Do you share any of the same traits as well?
Practice what you preach and indulge in looking "at the evidence in a analytical perspective while keeping the "common sense" composure if you will."
Can I rest assured you will not pick this as best answer?

You're apparently unclear on what consitutes a scientific theory.
A theory is an attempt to explain a natural phenomenon. This attempt must conform to certain rules of scientific rigor (testability, falsifiability, conformity with evidence and natural laws, internal consistency, the ability to make accurate predictions, etc.).
That gravity exists is a fact. The theory of gravity does not merely state that gravity exists. It goes much further, and attempts to explain how gravity works. It's a very useful theory, but it's not complete. There's a lot we don't know about gravity, especially on the sub-atomic level. You can read more about it here:
http://en.wikipedia.org/wiki/History_of_gravitational_theory
In this way, evolution is very similar to gravity. That evolution exists is a fact. The theory of evolution attempts to explain how evolution works. It is also very useful and not complete. There's a lot we don't know about evolution, especially in the distant past.
Evolutionary changes do not come about through "defective" genes. They come about through changes in genes. Whether or not that change can be considered a defect depends on whether or not it harms the organism's ability to pass on its genes to the next generation. Most of these mutations have no discernable effect on the organism at all.
We identify hundreds of new species every year. Understand that evolution does not happen overnight. An animal doesn't just jump out of bed one morning and decide to become a new species. In all but the rarest of cases, speciation (the process by which new species are formed) takes generations to occur.
There are certain eleven-finger mutations that DO pass to offspring. (I grew up near a family who all had twelve fingers and toes). Whether or not any trait will be inheritable depends on many factors.
Seriously, I'm not trying to offend you, but you seem to be VERY misinformed about evolution and how it works. If you want to learn more, check out the link below. You can also feel free to contact me through my profile, and I'll try to answer them as best as I can.

1. "Evolution is a theory!" is as irrational a statement as "Evolution is a banana!". Being a theory only means it is a well supported explanation of the data we have.
2. Gravity is composed of both Laws and Theories. Gravity cannot be claimed a fact unless one redefines gravity as being the phemonena of objects moving towards one another.
3. "Trueness"?
4. Common sense is not Logic. Common sense is a schematic form of logic, which is quicker to apply in situations. Logic is the proper method, with Common sense being a compilation of assumptions based on logical trends.
Logic ALWAYS takes precidence over common sense, becuase common sense only tries to emulate logic for the heat of the moment.
5. Change comes from variations in genes, not defective genes. Documentations of speciations are readily available at Talk Origins and PubMed (type it in google or yahoo).
6. This "11 finger phenomena" is likely to be a variant in alleles for a gene group. Perhaps the gene is haplo-insufficient and requires homozygous expression? Perhaps it requires epigenetic effects to be expressed?
Many possibilities here and not enough information to conclude on.
On a side note, a law and a theory is equivalent in likelyhood of being correct. One is an explanation while the other is a guideline/principle.

"One`s ability to take a test and pass thru a secular college is no genius"
Indeed, you're demonstrable proof that those who don't have a clue get through college anyway.
Scientifically, the "theory of evolution" is just as strong as the "theory of gravity." Both gravity and evolution are facts, but we have theories and models to explain how they operate. Natural Selection, Genetic drift, mate selection, and more are the operating theories to explain the biological fact of evolution. A scientific theory means it's observable, testable, repeatable, and it's true 100% of the time.
"Stress theory" is true 100% of the time, and it's the reason we have cars/buildings/planes/bridges/dams/etc. and quantum theory is accurate 100% of the time and it's the reason we have computers and cell phones.
Obviously you have absolutely no knowledge of the scope or timing of evolution... evolution occurs through small, incremental stages over incredibly long periods of time. Significant mutations (such as growing 11 fingers) don't usually lend themselves to reproduction, it's the minimal mutations that do. And change happens over a very long time. It takes thousands to millions of years for a new species to emerge, but your thought process is apparently too limited to grasp this. In the last couple hundred years humans have grown in height and our jaws have become smaller, give us a million and we'll look completely and utterly different than we do now.

You don't know what a SCIENTIFIC theory is. Look it up on wikipedia or something, its getting very old explaining it to kids who didn't pay attention in primary school yet think they actually know something.
Here is a sample of speciations that have been observed recently, off the top of my head:
Drosophila fruit-flies - new species were created in the lab by nothing more than isolating the population and giving them different food for generations
A new species of mosquito, speciated from the common mosquito in the London underground.
Several new species of plants via chromosome mutations.
Now lets see how honest you are.

In science a theory is an explanation that best fits the facts. So you are saying that macroevolution best fits the facts?
Also, in biology we use the term microevolution to describe evolutionary processes below the species level and macroevolution to describe processes above the species level. Since it takes a genomic difference of > 0.03% (give or take) to move from below to above the species level, to have microevolution be true and macroevolution not be true you would ned to have a nucleobase transcription error correction device kick in once reproductively isolated populations achieved a 0.03% difference. If creationists know of such a microevolutionary molecular genetic correction device please apply for the Nobel Prize.

Things falling is the fact. Gravity is the theory that explains the fact.
Evolution is the fact, and it's just as observable as things falling. Natural selection (the origin of species) is the theory that explains the fact.
If you want to observe evolution, get yourself some fruit flies and a high school education. You can watch fruit flies evolve because their DNA is so simple and their reproductive cycle so fast.

Hmm, who should I believe...
A moron on YA!, or Richard Dawkins, Stepthen Hawkings, and the 97% of Noble Laureates who accept evolution?
Tough choice.
Maybe if you stopped to learn the theory of evolution from a scientific journal and not a christian apologists website, you wouldn't make such a fool of yourself.
Btw, pick up a dictionary next time you are near a book store, the scientific definition of "theory" is NOTHING like it is used by the layman.

Perhaps you might profit by looking up the various uses of the word "theory" in a dictionary. Then, read a bit about genetics.

If micro-evolution is a fact, which it obviously is, then macro-evolution is too-species don't magically stop evolving at some point. Without providing a biological mechanism that would limit the extent of evolution in a species you can't believe only in micro-evolution.
