Most educators have long accepted as a fact that evolution proceeds as a consequence of selection and mechanistic mutation. We know that DNA, the genetic code, is compatible among all known biological beings. In some respects, the similarities between the genetic code of a bumblebee and a human are more striking than the differences. Thus, only a very dogmatic person would fail to se the continuity.
Creationists have long pointed to the gaps in the fossil record as evidence for divine intervention. On the other hand, the fossil record clearly shows that the less complex organisms appeared earlier in time. Thus, it makes more sense to believe that the fossil records is incomplete for reasons that are unknown but scientifically understandable than to believe that intermediate species never existed in the evolutionary chain.
I have been very careful to speak of reasonable belief rather than of proof. All knowledge is fallible. It is not impossible that the world was created roughly six thousand years ago and that our carbon-dating and other scientific techniques produce plausible but incorrect conclusions. But anyone who would assert the truth of this has left the court of reason, and if he uses evidence at all, uses it only to illustrate a belief based on religious conviction.
However, as the interview of the noted astronomer Chandra Wickramasinghe in this issue of The World & I makes clear, the current accounts of evolution are unsatisfactory despite most scientists' dogmatic faith in them. The problem with the evolutionary theory is much deeper than the usual issue of whether evolution proceeds by slow stages or by jumps. The
