If there is anybody following this, please notice that there was a point in the paragraphs I wrote, a point that was totally lost when Dad broke things into tiny bites.
We were looking at the series of horse fossils with time, from eohippus to mesohippus to miohippus, etc., and I was asking you why you think they consistently appear in that order. And it seemed to be you were saying that it was just luck that all the eohippus went in one layer, all the mesohippus in another, etc. But now you are back to nature somehow selecting only eohippus fossils when the layer that dates to 55 million years was layed down, and nature somehow selecting only mesohippus fossil in a later layer, and nature somehow selecting only a different kind of fossil in the next layer. So you seem to be back to nature constantly changing which fossils it selects. That makes no sense.
You totally ignored the question. Again, there are fossils that date from 65 million years ago to 1 million years ago, but the eohippus all appear at about 55 million years ago. Why is that? Your answer makes no attempt to address the question.
