daperl. You can't just hone in on the first sentence to the exclusion of all else-- it wasn't the most important portion. You are willfully excluding critical context just to argue it seems. I already highlighted the word that was germane, sooo... why the axle wrap? I don't see how anyone can argue that if our environment changed to be hostile to man's continued existence, another species more appropriate to the new condictions couldn't fill the vacuum. In fact, I'm betting Richard Dawkins would be right on board with that.
