"The next-generation of the KDE open source project, version 4.0, has been touted as the beginning of a new era in desktop computing, but only two months from the first release some users are wondering if it's just all hype. KDE 4.0 will bring a collection of new technologies to the Linux and Unix desktop, but there are uncertainties around how much of it will be included in the initial release. KDE user Andreas Pakulat expressed doubt about how the release will take shape in a blog post titled 'Where's the KDE4 desktop?'." KDE's Aaron Seigo also shares his thoughts on this.

The point is that over the course of millions of years, species barely change. And then, probably due to external pressure, they change rapidly. This explains partly why so many 'missing links' can't be found. And those are the jumps I'm talking about. Again, if you read up on it, you'll see this is a pretty accepted fact in biology.
And yes, jump is relative - we're still talking a long time. But you know, Computers do everything faster than biology does ;-)
And of course, this analogy doesn't have any real value, it's just a way to explain stuff, I guess ;-)

_My_ point was it _doesn't_ happen rapidly. It's a widely accepted _fact_ that evolution is gradual, the only reason we have missing links in our ancient history is simply because they haven't existed for such a long time that there's no physical evidence that has survived. _That_ is how gradual evolution is. There's absolutely _Zero_ evidence to the contrary.
The only reason we evolve at all to any _major_ degree is external pressure ie monkeys > humans but again its all gradual. Sure it might seem big if you compare how little a monkey today differs from one a few million years ago but it's still gradual. To use the word "rapid" is quite silly.
That said, _some_ previously "missing" links have been found in recent years frozen in glaciers. Trying to tell me evolution is anything but gradual is quite frankly, ridiculous 
Back to the topic of software:
My original point with this seemingly unrelated analogy was that nature doesn't replace things that don't need replacing. Developers do. There is very little code-reuse. I'm not saying KDE4 didn't need to make the changes it did, because it likely did(especially with QT4). What i'm saying is the whole approach of rewriting everything every couple of years is massively flawed, slower and bug ridden.
I'm sure a lot of you remember the <=2.4/2.5 linux kernel series with a stable and development branch. That approach wasn't a good one - and it showed. The huge number of bugs, the massive development time required to make huge rewrites work (vista anyone?) is just not worth it in a lot of cases.
The 2.6 kernel thankfully provided a framework good enough to break away from that flawed development model and I think the massive improvements in the kernel since 2.6's release compared with previous releases speak for themselves. Hopefully QT4 and KDE4 will end up like the 2.6 kernel series and not just another framework rewrite / rewrite of which there are millions. Maybe i'm just old and bitter but this endless rewriting trend really ticks me off sometimes.
Don't get me wrong, I have high hopes for QT4/KDE4 I just don't want to see another rewrite a year or two down the line. I've seen it happen to so many projects, so many times. Heh writing this makes me wonder if one of my favourite WM of old (enlightenment) will ever see a new release. It's starting to become the duke nukem forever of window managers. Surely there has to be a limit to how many times you can rewrite the same thing?

Sorry but to me tens of thousands and hundreds of thousands of years (if not millions) IS gradual.
Adaptive radiation hasn't applied to humans for millions upon millions of years and even then there has only been one "recorded" case of it - This also has no effect on the speed of our evolution. It has always been a gradual processs.
You seem to forget we share over 90% of our genetic code with mice - sure we've changed a lot. But this gives the real big picture when it comes to evolution - extremely gradual, always has been. Millions of years is certainly not "quick" to me.
You can call hands (as an example) revolutionary but really the difference (physically) from what they evolved from is very minor and yet it still took millions of years, absurdly gradual. The only change I can thnk of in the last hm? 2000 years is a height increase, other than that we're pretty much exactly the same we were 2000 years ago.
