The "design" part of evolution is the decision of which creature survives, and which does not. That is a very powerful generator of information, as demonstrated by experiments at Caltech's Digital Life Lab.
Besides the validation that evolution theory increases information content, the verification of common descent is very well established by a few thousand ERV virus sequences in common among humans and other primates. We understand how these virus segments get inserted into the genome, and these common sequences are proof that we share common ancestors millions of years ago. Not merely share common ancestry with another species, but that species such as New World Monkeys and humans have a single *individual* we are both descended from. I.E. Great, Great ...... Grandpappy.
That's the facts. If someone wants to explain some other way we share common ancestry with an individual primate millions of years ago, fine. But I have no problem with evolution, and I won't tolerate lying to school children and telling them that evolution is false.
