that was a different chapter of the same series. supposedly the only mammals left by then are rodents being farmed by the spiders like livestock. Personally, I think a bunch of bored scientists got a new graphics program and a shipment from columbia on the same night.
That's probably one of the truer things I've ever heard. Talk about throwing guesses out. How about some spider, but they're smart??? If scientists can't solve all our problems, what do we pay them 25 grand a year for?
