junk dna is a farse, vestigial organs do not exist. the tonsils boost the immune system, the appendix aids in digestion, the tailbone has 9 muscles attached to it that allow us to stand and walk.
the whale's "vestigial" pelvis is vital for it's reproduction.
as for other animals, every piece has a purpose. we just haven't always found it yet.

There really is no "junk DNA." There is only DNA that we have not figured out the function for. Many series of random repeats were for a long time thought to be just a waste, but it does have purpose in genetic labeling of families, an protection of telomere ends of DNA, which ,if destroyed, would lead to early aging. The random areas also help with the overall structure and supercoiling of the DNA. The same is true for what we currently consider vestigal organs. They also have some function that we have not yet discovered. We focus research on priority issues due to restrcited funding. Maybe in time, we will be able to better answer questions like this.

First of all, the word is vestigial, and not vestigal. And it refers to a degenerative structure; I.E. not being used.
Just because science can't figure out what the use of the appendix , tonsils or other organs are, does not mean that they have no use. Nor does it mean that God made a mistake.
It simple means that man's brain can't compare to God's. And wouldn't it be funny, years down the line, that science does catch up to the intent of God's design. I wouldn't want to be the one that had my appendix or tonsils out then.
Junk DNA is a man made term. What do you do? Knock the chess board over as soon as you know you can't win, and say, "this is a stupid game"? Nothing is considered Junk, just because science can't figure out the puzzle.
Adam lived until he was 930 years old, and God hasn't changed His blueprint for man yet.
Just because today's man doesn't even have a life expectancy of 85 years, is attributed to other factors. Changes in environment, global warming the ozone layer, aerasol sprays, eating red meats all contribute to the degeneration of organs like heart and kidney failure, but once again, you can't blame God for that. Place the blame where it belongs: with man.

What once were thought of as vestigial organs have now been found to have purpose. Why junk DNA you ask - why decay, why disease, why catastrophe? All good questions. Death and decay are a result of sin in the world. This world is not as it was nor as it someday will be.
Here is a great link for further and more exhaustive study.

Sorry to only address the first topic, I thought my post was long enough...
"The UBC team has found experimental support for the usefulness of non-coding DNA in their study of cryptomonads (algae). The non-coding DNA appears to have kept the volume of the nucleus proportional to overall cell volume. Additionally, they found evidence refuting the “junk” or “selfish” model. A specialized cell part called the nucleomorph behaved opposite to what the naturalistic model predicts and exactly as the “purposeful” model predicts."
"A number of important functions have been identified for so-called “junk” DNA in the last five years.4 Even with these findings, one class of “junk” DNA remains problematic from a Design standpoint. That class is called LINE (long interspersed nuclear element) DNA.
The recent work by the CWRU scientists effectively addresses this concern by identifying a functional role for LINEs in X chromosome inactivation.5 X chromosome inactivation occurs in healthy females as a way to compensate for duplicate genes found on the X chromosomes.6 (Recall that females have two X chromosomes, whereas males have an X and Y chromosome). The inactivation of one set of X chromosomal genes ensures proper level of gene expression for individuals with more than one X chromosome.
Scientists are beginning to understand the molecular mechanism of X chromosome inactivation.7 Inactivation begins at the inactivation center, which contains the Xist gene, and then spreads along the X chromosome. The Xist gene on the inactive X chromosome expresses messenger RNA. Messenger RNA is a molecule that is similar in structure to DNA. Messenger RNA contains a copy of the information found in DNA that is used to direct the synthesis of proteins. Messenger RNA does this by migrating from the nucleus (which houses the DNA) to ribosomes found in the cytoplasm. It is at the ribosomes that messenger RNA directs protein synthesis. The Xist RNA never leaves the nucleus. Rather, it binds to and coats the entire length of the inactive X chromosome, with the heaviest coating occurring at the X-inactivation center. In contrast, the Xist gene is “turned-off” on the active X chromosome.
The work of the CWRU team strongly implicates LINEs as the binding site for Xist RNA. Data from the Human Genome Project shows that the X chromosome contains a significant enrichment of LINE sequences compared to other chromosomes. The greatest concentration of LINEs is at the inactivation center. Moreover, sites that escape X chromosome inactivation lack LINE sequences. The recognition by the CWRU team that LINE DNA functions in X chromosome inactivation adds to the growing evidence that the genome is the product of a Designer."

Even if we were created by God, this does not mean that we are now as we were then. We have changed since then because we were kicked out of the Garden of Eden and made to wander the lands - so we evolved in accordance with environmental / social factors. Thus, some things were made vestigial...

What scientists previously thought of as "pseudogenes" have now been determined to be genes that have been switched off through our evolution. For example, one of our genes that we share with other mammals, is still active in mice and many other mammals. It allows for the production of vitamin C within the body. However, in primates this gene got switched off 40 million years ago. Perhaps because they didn't need it because they were eating so much fruit. When in the womb, the human fetus goes through stages that show our evolutionary past. For example, the appearance for a short time of fish gills in the neck. There are many of these "switched-off" genes from our evolutionary past and by studying these, scientists should finally be able to prove evolution within the next several years.

What vestigal organs? Which organs do you think are vestigal? The heart? Brain? Kidneys? Appendix? Believe it or not, the appendix isn't even vestigal. This is well-documented. Kidneys? What organs do you think are vestigal? hehe

Because God likes to write redundant things and then make them irrelevant.
Just look at the whole Old Testament.
