What, you have a bunch of skulls of...gasp!...people who are DIFFERENT from each other? What a discovery? /sarcasm
But wasn't the evidence valid when it was supposedly missing?
- Tap-Dancing Science-Denier declares that the fossil record lacks instances of things changing in an orderly series from some Thing A to Thing Z. As this kind of evidence is to be expected, the lack of it must weigh against evolution having happened. By the very statement of this objection we are invited to believe the Tap-Dancing Science-Denier would accept such evidence IF ONLY IT EXISTED but the thing is it doesn't exist.
- Someone who disagrees demonstrates many instances well known in the literature of fossil series intermediate in form and time between some Thing A and some Thing Z.
- The Tap-Dancer then declares fossil series evidence to be irrelevant. How do we know ... various things? The dates of the fossils? Whether fossil A lies exactly on the ancestral line of fossil B?
The gradual sequence of fossil change as shown in the "bunch of skulls" demonstrates intermediate fossil species. If you disagree then what would intermediate fossil species look like instead? If you don't know what intermediate fossil species should look like then how can you be sure none have been found?
Forgot to say, "Congratulations on being an extremely fast if not at all accurate reader!"
