Why did the native americans lose

I want an answer to this question beyond the euro centric view that "they lost cause they were backwards"

If anything pisses me off historically, it's that. It's not a concrete answer and summarizes it all up in a simple sentence, but there's more to the tale.

To say that the natives were backwards is bullshit. For one, they had canoes, that could maneuver the waters while the Europeans were stuck with shit boats that didn't move. Just because it isn't made out of iron doesn't mean it's not better. If anything, the natives were backwards when it came to weaponry, not everything else.

Darwin sez;strongest kicks the most ass and wins. Otherwise, the Natives developed their own societies as well. But why wasn't their weaponry as advanced? Why did they lose?

Let's see.  Continent inhabited by a few hundred thousand inbred IQ-55 Eolithic cannibal cavemen who lived in widely scattered tiny bands, who never had a written language, never had the wheel, never even had copper or bronze, is conquered rapidly by millions of IQ-100 Europeans who had horses, gunpowder, and iron.  Hmm.  And >>1 is stumped, and can't figure it out.

Gee, I can't figure it out either.  Maybe their gods didn't love them.  Maybe they were just really unlucky.  I'm stumped too.  Anyone have any possible explanation?
