I was looking up things about evolution and i ran into a wall. What about the holes in the Fossil record? Shouldnt there be a lot of fossils of evolutionary dead ends? And what about the lack of transitional(Sp?) fossils?

What about the holes in gravitational theory?

Anyway, you need to look harder. There are transitional fossils of various things all over the place. Some lines have more than others, some less or none yet found. As for evolutionary dead ends, you mean like the dinosaurs? :confused:

We're lucky there are fossils of anything at all.

The chances of fossilisation are very very small, and some organisms fossilize more readily than others. Also, we have barely scraped the surface in terms of "finding all the fossils".

I don't know what you mean by "evolutionary dead ends". We do know that about 99% of all the species which have ever lived on Earth are now extinct, which means that 99% of all fossils are fossils of animals which no longer exist alive on Earth. So, if that's what you mean by "dead ends", there's no shortage that I can see.

By "transitional fossils", I assume you mean fossils of animals which are "half way" between known species. There's no lack of those, either. For example, we can find a whole string of fossils leading from primitive horses to modern horses. There is a whole string of fossil species leading from ape-like humanoids to modern humans. There is a whole string of fossils leading from a kind of pig-like mammal through to modern whales.

It is a common creationist tactic to always ask for the "next" transitional fossil. If we find a fossil C which is intermediate between two species A and B, then creationists switch to asking for intermediate fossils between A and C or between C and B, instead. No amount of fossils is ever enough for them.

It should be noted that every organism is in transition. We're all transitional forms. From species A to species B there is not an (A+B)/2 that is the intermediate step between the 2. Instead there are many organisms along the way from A to B.

And James is right, the chance of fossilization is very very small, and our chances of finding a fossil are also small. We keep finding them though, but there is no way we will find the fossil of every organism that ever lived.

With that said, the fossil record is pretty deep, and I encourage you to keep looking for information.
