We have never observed, either in real life, or in the fossil record, any line leading from simple organisim to a more complex organism. For instance, there is no evolutionary line from fish to man (as evolutionists would have us to believe). Instead, what we find are organisms that appear quite suddenly in the fossil record, and the ones where we can trace them up to modern times devolve (in most cases only slightly) from their original kinds.
Again, I’m going to have to ask you whether you are asking for a 500 million year videotape. You are pseudo-quoting Stephen Gould on the sudden appearance of new species.
Gould’s evaluation of people who misuse his writings is that they are either dishonest or stupid.
