Ok, but that should just make us further question whether the Balto/Togo story really has anything in common with the history of tectonics. There isn't a clear obvious hero and a hidden hero (both of whom somewhat undeservedly singled out from the group effort), there's just one well-known name, and it's not even clear which of the two characters he'd correspond to.
I agree that the Balto/Togo story doesn't fit quite so neatly into the Wegener story, but I also think the article brings up a good broader point that credit is often given to people/dogs that seem undeserving when you dig a little deeper.
