Stasis and Evolution

Very good post, I think, but you may want to look at the formatting of your table. The information in it is confusing (to me at least) and the fact that every row but the first is pushed one cell to the right makes it even harder to understand.

I think it's an interesting concept, and maybe it could be expanded and detailed more. For example, what units of measurement are we using for the change: Mutational rate, phenological differences, survival rate? I understand it was just thrown out there, but I think it could be developed if someone wanted to spend the time to do it (meaning not me )Once we have that, we could, perhaps, show some actual numbers for the changes between, say, Archaeopteryx and an Ostrich, versus an extinct land mammal and the whale, etc.
