How You Know This Shit Was Written By Men!

[Thumpalumpacus]

No one said anything about purpose, the point being made is that humans aren't cut from the same cloth as the used to be...

... if beating the snot out of each other is your metric.

Me, I think it's a good case for cultural evolution that we don't engage in such stupidity. As for biological evolution, you'd have to make the case that we're actually incapable of such antics due to the mutation of our genotype in order to support your point that we've devolved. And the change in alleles over time is the metric for evolution -- or de-evolution, for that matter.
