I have only skimmed through the comments posted, but I will add my two cents into this debate. Similiar anatomy among organisms is not proof of evolution as they form differently. An example would be a frogs legs grow outward from buds while a humans digits form as a plate and get "carved" away. They are also determined by unrelated genes.
Aonther thing, somebody mentioned why don't humans have eagle eyes, or chimps have dog noeses (or something along those lines). I would like to point out that the squid has similiar eyes to a humans eyes. A duckbilled platypus has a beak and lays eggs (I am not sure if they are exactly like bird eggs, but the fact that a mammal lays eggs should be impressive to any evolutionist). Algae, worms, insects, and fungi all have some organisms that can glow in the dark or produce light. Some of them do it diffrently than others while others do it the same. It would take many different mutations to allow all species that have light to produce it.
About the tail thing. The tail with actual bones in it would probably not serve any animal. First off I assume that the tail is non-functional. (I am not sure on that). Next thing is the tail is only a few inches or centimeters long. I don't understand how a a 10 cm tail would serve a monekey.
Last thing is the tail in the embryo development. Sometimes it only looks like they have similarities. When human embryos have a "tail" it is really just the coccyx. The coccyx is an important bone structure used to anchor muscle structure.
