No.1 Doubt the fossil record.
Darwin’s theory has always been closely linked to evidence from fossils yet do they show the gradual changes that he predicted ?
If there were no fossils, the evidence in favour of evolution would still be overwhelming. The only reason the two are linked is because fossils are an obvious phenomenon that needs an explanation. Even by the 18th and 19th Centuries it was clear that there were certain 'ages' and a certain pattern in the fossil record that needed a better explanation than was offered.
Evolution provided such an explanation.
Even more compelling is that as new fossils are discovered, we find them consistent with evolution and the natural history so far described. There are times when a few ideas need to be shifted around but the big picture remains the same.
Darwin did not predict phyletic gradualism (slow, steady change at an even rate), he predicted something akin to punctuated equilibrium:
quote:
It is a more important consideration . . . that the period during which each species underwent modification, though long as measured by years, was probably short in comparison with that during which it remained without undergoing any change -Darwin

Re: Selection Pressures
The only difference between Dawkins programme and my example is that one came from an evolutionist, one from a Creationist. Ergo, it is a matter of faith and doctrine for an atheist that you support the former and condemn the latter.
There are a lot of differences between the two.
Dawkins was trying to illustrate that what might be impossible by random mutation alone becomes possible when you apply the principle of natural selection.
Close, but no cigar. Dawkins was explaining how cumulative selection can change an improbable event into a probable even inevitable event.
To do this he had to use a TARGET which was "METHINKS IT IS A WEASEL" and the fact that evolution cannot have a TARGET is the little hidey-hole you bolted down in order to evade the impossibility of evolving a gene. Evolution is random, remember? It isn't trying to build anything. It can't have a TARGET.
There is no predefined target - but there are many many outcomes which are possible by the laws of chemistry, some of which lead to increased reproductive success. Meaning there are many possible 'targets', which are difficult for humans to work out in advance and are certainly not considered by natural processes.
Evolution isn't random - remember! It is not directed by an intelligence - but it is directed by contingency and environment.
