Default Re: LEGALIZE IT

So why aren't humans evolving anymore?
When did this happen?

SOme researchers think if anything, it's been speeding up recently.

the genes that made the fittest may now make for the weakest, or whatever. So the genes don't keep getting passed on more than the others the way it does in darwinian evolution.

But since those "weakest" traits aren't being selected against, doesn't that just mean something like that they're more neutral in our current environment? This is not in opposition to darwinian theory.

Okay, that was off the top of my head, but from my understanding of evolution, a couple of generations or even a couple dozen just aren't enough for any relevant evolutionary change to take place.

Why not? Think about isolated populations. Think about drastic changes in the environent. Think about disease resistance, metabolic changes, population migrations, etc.
