$this->bbcode_second_pass_quote('', '
')You missed the point. Of course the long term picture shows gradual changes as you pointed out. But if you get down to the species level, there is a mysterious dearth of supporting evidence for smooth transitions.
I though the hard part was to explain gradual change on a macro-level? If you want species specific gradual evolution, I have mentioned homo-sapiens and horses and dinosaurs to birds (down below).
How detailed and specific do you think the fossil record should be? Concidering, again, that fossils of animals are a rare occurence even under the special conditions required? Should records show every dead progeny from an ancestor animal from a period of time of several millions of years?
Again, dinosaurs to birds transitional fossils show a slow gradual change from one species to another, for example Archaeopteryx and it's place in reptile to bird transformation.

In the end, I'm not saying that evolution concists solely of gradual random mutations. Symbiogenesis and quantum-level evolution are also possible explanations for PARTS of overall evolution. But gradual evolution certianly exist, and has been observed. Observed mutation rates often corrolate with fossil dating etc.
