But that is certainly NOT what Gould meant at all.
I disagree. The distribution diagrams show that not only are gaps systematic but the dotted lines don't even join up to anything other than more dotted lines. Gould meant it literally.
That runs into one BIG problem. It isn't what Gould was talking about at all. Gould was attacking an extreme gradualist view which was at the time assumed in paleontology. He was talking about a lack of transitional fossils between a species and other species immediately descended from it. He and Eldredge went on to apply evolutionary theory to the problem and produced the original version of Punctuaed Equilibria.
I kmnow all about PE. PE was required becasue of the distinctness of the fossil groups.
Gould himself later said that transitional fossils between higher taxa were "abundant".
And I fully agree with him with the proviso of inverted commas around the word 'transitional'! Whether we talk from fish to amphibian to reptile or within orders you can get apparent transitonals but they are distinct organisms. They are simply organisms buried in a pattern of sea-floor to marine to aquatic to land. The more similar the closer they are vertically!
The crown jewel of transitonals is the mammalian reptile sequence. Look what evolutionists say about it:
' . . . each species of mammal-like reptile that has been found appears suddenly in the fossil record and is not preceded by the species that is directly ancestral to it. It disappears some time later, without leaving a directly descended species . . .' Tom Kemp, 'The Reptiles that Became Mammals', New Scientist 92:583 (1982)
You said:
Your problems are far worse because there is so much data against your view. The problem of "ghost lineages" is due to a lack of data - the equivalent of an "argument from silence". And an argument that has proven unreliable in the past.
I have been at pains to point out that the ghost lineage problem is a systematic one for six seperate groups only because of evolutioanry assumptions about three other groups. You can believe the problem will go away if you want.
Michael Behe used to point to the absence of transitional fossils for whales as a problem. Then in the '90s those missing fossils were found. So there is a recent example where the problem was not even the fossil record, but just our limited knowledge of it.
Your supposed transitonals here are weaker than those of the reptile-mammal transition.
