If it was some day demonstrated that humans and chimpanzees were capable hybridizing to produce offspring, would this peg them both as being the same "kind" as defined in creationism? Would anything about the creationist model needed to be modified if this turned out to be possible? Could it be posited as nothing more than a strange coincidence or would one need to say that God designed humans and chimpanzees to be genetically compatible in order to explain it?
