Okay, so the ring species is a very strong evidence for evolution, I know that. I don't know where I saw a video about it, but it might have been from Cdk007, Don, Thunderf00t or Shane, don't remember. But I know what it is and I understand the shit.
But I wonder is. How come that hasn't applied to humans? I mean, now, I can understand, travel is very instant, doesn't take time at all to meet our own species at a very different part of the world.
But a couple of thousand years ago, that didn't exist. So, how can it still be possible for an African to mate with an American?
Now, I've been thinking of it, and what I can come up with that. There hasn't been enough time and/or humans moved very quickly from Africa through Asia to America. Am I right?
Another thing is that humans tend to adapt the environment to them instead of the other way around. (Natural Selection that is). I.e building tents, using fur from other animals to keep warm, making fires etc which makes the chance to live much higher so the chance of a new species to emerge would be smaller. Get what I'm saying?
So, Moving fast + fighting nature = No new species. Right? The only change must have been to those who wandered, like, how they survived the weather and climate. But with them moving fast, they stayed as Homo Sapiens.
How accurate am I? Or am I way off?
Oh and, I don't know how long it took for the Ensatina salamanders to evolve. Anyone knows?
Thankful for answers!

It'll probably take more than a few thousand years for two populations to diverge into separate species. As long as every human can procreate with every other human, we're all the same species.

Exactly! But how long did it take for the salamander to evolve?
Or, how long would you think it'd take?

Humans also have (as I understand) an relativly unusually lang ''generation-time'', it takes about 20 years to get a new generation, so evolution moves slower on us.

Divide the human population into groups based on religion (and lack thereof). Make it so that the different populations cannot enter areas reserved for other populations. Wait long enough and morphological differences will be huge.
Wasn't there some kind of projection saying that in 50 years there will be no more blued blonde haired people...or was that bogosity?
It's bogosity. (http://www.snopes.com/science/stats/blondes.asp)
Ah. Thanks. ^_^ I had heard it mentioned a long time ago, and never looked into it.
