No, not really. Peg's sole point, if it can be dignified with that name, was that the existence of different pigs in different places at the same time somehow invalidates geology.
Actually, that was not my point.
Coyote said that "Sediment layers are not interrupted at that time over continental areas by a discontinuity."
I questioned using the sediment layers as a marker because as is seen in the layers of sediment from the Omo and Lake Rudolf areas, they are not always consistent with each other. In the example i gave, the pigs are in the same sediment layer, are dated to the same time but are a different types of pig.
I was not calling into question geology as a whole....even though the geologic column IS a hypothetical structure.
But to Pandion, as usual my clumsy remarks have caused a ruckus and i apologize for that.
