I'm not sure what your point is regarding the KT event? The Permo Triassic extinction is also worth looking at to prove your point wrong.

Evolution can happen on numerous time scales (and probably on a larger timescale than the 10's thousands of years you mention) - it`s all to do with the availability of competing environmental pressures and other species within an ecosystem.

Naturally, there are biases within some science; we`re all human. However, the broader principles in Geology operate under the theory of uniformitarianism, laws governing the planet now, governed them in the past.

The principles behind geology are generally robust and interlinking - for example: `theory b relies on theory a to exist, theory c was formulated using scientific laws which were deduced and require a&b to be correct`. It`s a bit like filling in a gaps in a crossword. A number of the arguments used by creationists to denigrate evolutionary theory jump in at accepting theory c, but do not accept theories a&b (which are crucial for c) however theory c cannot exist, without first accepting that theory a&b are c

"The pre-cambrian contains very few fossils (there wasn't a lot of life back then)."

According to evolutionary theory diversity of life doesn`t just explode suddenly, it takes tens of thousands of years of gradual adaptation. But that`s not what the fossil record shows in the pre-cambrian or post-KT boundary layers.

"one has to be careful when cherry picking at the scientific data and choosing which parts of it you wish to believe and which to dispute."

Scientists do that all the time and they get away with it. They just keep picking at the data until they get the result they want. It`s called "Experimenter`s bias" and it happens all the time. It`s also not the only bias` that creeps into science there are other influences too.

The pre-cambrian contains very few fossils (there wasn't a lot of life back then).

Fossil records tie in with other means of dating rocks. There are probably dozens of ways to do this. The `gaps` can be fairly.

Biostratigraphy is just one branch of stratigraphy for example.

It takes very little explanation regarding why some animals haven`t evolved; they haven`t needed to. I have no beef with creationism, each is entitled to their beliefs. However, one has to be careful when cherry picking at the scientific data and choosing which parts of it you wish to believe and which to dispute. Science relies on empiricism and has a kind of an all or nothing approach. E.g. you can`t claim on the one hand that some fossils show no signs of evolution, but on the other ignore those that do.

Mr.Rugby "the fossil record is however fairly comprehensive."

Not really, no it isn't. We are missing tens of millions of years and intermediary steps. Not to mention explanations of the pre-cambrian explosion and the post KT boundary explosion.

It also takes some explanation as to why many of the oldest animal species on earth are still essentially the same as they were, and haven`t evolved, since their introduction.
