Nobody discards "old" science discoveries, any more than they discard the "old" inventions of steel, or indeed the wheel, they build upon them.

Re-visiting previous studies with newer approaches is a common theme in archaeology, where sites or artifacts are sometimes incompletely investigated on purpose, with the view to leaving undisturbed material that can be investigated in the future using technology not yet conceived of.

I hope this doesn't make me sound like a hipster, but I can't remember the last time I saw a wheel.

How did you get to work today? Even if you walked, are there really no vehicles along the road?

So, I was actually making a joke :)
