As a practicing biological scientist, I must admit to being alarmed over the tenor of arguments advanced by many believers in fundamental religious teachings, who seem to take it as a given that belief in the teachings contained in especially the Christian Bible are incompatible with "evolutionary theory".  This is very true here in South Africa right now, with news that the Department of Education is going to mandate teaching of evolution to senior secondary school learners. 
The central tenet is, of course, simple nonsense - unless you believe that everything in the Bible is literally true.  And if you believe that, then - as others have previously pointed out in the context of the Biblical proscription of homosexuality - then you should also believe that slavery is acceptable, that you may kill your neighbour for working on the Sabbath, that you should avoid contact with menstruating women, and that you should not wear glasses when approaching the altar of the Lord, among many other strictures incompatible with modern life.  Oh, and that it is perfectly fine to stone your neighbour for wearing clothes made of more than one type of thread.  Which doesn't seem that bad an idea if they are wearing those godawful two-tone shirts from Mr Price...but no, no, perish the thought.
And if you believe all you read in divinely-inspired scripture, why then, I have a new one for you....
Why do people who presumably accept the fact of gravity not accept the fact of evolution?  For all the nonsense written and spoken about evolution, like gravity, it IS a fact.  We may argue about exactly how both of them work, which is where theory comes in, but the facts of the phenomena cannot be doubted by anyone who understands the evidence.  Which, in the case of gravity, means falling on the floor if you lift both legs up.  Unfortunately, evolution is a little harder to demonstrate in action - and denial of its existence has fewer immediate consequences.
But consider this: evidence of micro-evolution happening right now is all around you, in the form of flu and HIV and TB, which persist because the agents continually change so as to avoid their hosts' immune systems or the drugs designed to combat them.  Ignoring the fact of evolution in the case of these three and other disease agents is tantamount to signing a suicide letter on behalf of our species. 

There is in fact, directly contradictory to many assertions, increasing evidence of past macro-evolution in fossil "transitional forms" of especially vertebrates, which for instance illustrate very clearly just how fish became amphibians.  There is a very nice Web page associated with the Public Broadcasting Service (PBS) in the USA, which graphically demonstrates this and other evolutionary facts.  Discover magazine also has a very good short article debunking much of what Michael Behe, a renegade biochemist and ardent intelligent designer, has to say in a new book on the limits of Darwinism. 

As for new genetic evidence, just today I read in a recent New Scientist (Oct 27) of genetic evidence from modern lungfish pinpointing just how limbs developed from fins, in extinct lobe-finned fish.  All in all, we have evidence of well-established life on this planet from over 3 billion years ago - and a pretty clear idea of how we got here from there.  Among people who understand the evidence, then, there is no doubt of evolution as a fact.  And the nice thing about evolution is that we can always find more evidence for it, palaeontologically and biologically - so that any "theory" (like intelligent design) which exists only in the cracks of the imposing edifice that is evolutionary fact, will inevitably be squeezed to death. 

Which is the evolutionary fate of all unfit theories....B-)
