Robert (or indeed Peer or any other YEC who happens to be following these threads) I am waiting with eager anticipation for you to explain on what biological grounds you assign the raven and the dove to different kinds while lumping bears, dogs and seals Into a single kind, and marsupials as different from each other as the red kangaroo, the koala, the recently extinct Tasmanian “wolf” and the sugar glider into another single kind. My own formal science education ceased when I was fifteen, and you, Robert, appear (excuse me) to have still less, and have written scathingly about science, but elementary observation, without any need for either genetics or anatomical study, is enough to convince me that the raven and dove are far closer in every way than the dog and the seal, let alone the kangaroo and the sugar glider. Indeed, I’m pretty sure that my great nephew, at only fifteen MONTHS, could do as much. (Having learned to pick out a magpie in a picture book, he quite spontaneously called out “magpie” when he saw one in the park, and in a museum, when we adults were admiring quite other mammalian exhibits, pointed to silent footage on an overhead screen I hadn’t even noticed and called out “shark”, which indeed it was – a great white.) Admittedly, based on film footage only, I dare say he’d consider the Tasmanian wolf a sort of dog, but that’s an error that an intelligent adult might also make in the absence of any anatomical examination to reveal it as a marsupial. So here’s the challenge – explain,without recourse to the bible, in terms that make sense to either a fifteen month old, a fifteen year old, or someone with a degree in biology ( your choice of level) why a raven and dove are different kinds from each other, when a dog and a seal are the same kind, and so are a sugar glider and a Tasmanian wolf.
