I don't know if I have time to really delve into this thread, but this comment caught my eye.
- AIG is assuming that rats and guinea pigs are more genetically similar to each other than humans, simply because they are both in the order rodentia. Without data this is just a layman's assumption.
Um, isn't that a reasonable assumption if we assume orders denote genetic similarity? Are we to think that something can evolve itself into an order from another existing order, and if that is the case, then why do evos assume common descent in the first place?
