Since this has absolutely NOTHING to do with the discussion this is a PURE Ad-Hominem attack.
Hg you made your point when that was the topic of discussion, but this is inappropriate.

Does the Bible explain how computers work? Don't be ridiculous. The theory of evolution is to explain the origin of the species and NOT to explain the origin of life itself.
Science doesn't even have a workable theory of abiogenesis yet. All it has at this point is a plausible suggestion and a VERY understandable lack of evidence that can only be expected. Scientists are left with working with the basic theory to try to piece together how such a thing could happen. Strides have definitely been made but it is clearly a long and complicated process that has to be worked out and that will take a considerable amount of time to do.

What is not been shown sufficient for what?

Well let me begin by saying that puctuated equillibrium is a bit of an oversimplification. I would not say that there are no gradual changes or even that changes necessarily occur as rapidly as "punk-eek" suggests. A gradually changing evironment is a good example of where we would expect to see a gradual change in even a large stable population. But we should often expect a lot of evolution to occur in small populations on the brink of extinction where we would expect little or no fossil evidence. We should not assume that evolution is occurring in a universal manner over the whole population of a species when in fact that is NOT what the evidence suggests. On the contrary, the evidence tells us that evolution (especially that of man) is one full of many many dead end branches. Thus while the fossil evidence reports the large stable majority, it is the separated minority, leaving practically no fossil evidence, but living during the same period where a lot of the evolution is happening. In this way, a struggling minority can gain the evolutionary upper hand and then it is the previous majority types that are now struggling to compete so that their population begins to decline. And of course, competition is only one of the possible environmental causes for a population decline.

One of the things life evolves is the ability to evolve itself, and so when living things evolve something like DNA, the eukaryotic cell or multicellular organization then it is natural to expect the whole evolutionary process to accelerate. Furthermore there are all kinds of environmental and climatic changes that give reasons to expect changes in the rates of developments like that.
