Humans may have migrated out of Africa in phases based on the weather

Parton and colleagues writing in Geology, present a unique alluvial fan aggradation record from southeast Arabia spanning the past approx. 160,000 years. Situated along the proposed southern dispersal route, the Al Sibetah alluvial fan sequence provides a unique and sensitive record of landscape change in southeast Arabia. This record is to date the most comprehensive terrestrial archive from the Arabian Peninsula, and provides evidence for multiple humid episodes during both glacial and interglacial periods.

Evidence from the Al Sibetah alluvial fan sequence indicates that during insolation maxima, increased monsoon rainfall led to the widespread activation of drainage systems and grassland development throughout regions that were important for the dispersal of early human populations.

Previously, the timing of episodes of increased humidity was largely linked to global interglacials, with the climate of Arabia during the intervening glacial periods believed to be too arid to support human populations. Parton and colleagues suggest, however, that periods of increased rainfall were not driven by mid-high latitude deglaciations every ~100,000 years, but by periods of maximum incoming solar radiation every ~23,000 years.

Sadly this thread has been poisoned and, regrettably, partly due to my responding to your juvenile insults. I don't have to elaborate to the likes of you. I never called you a liberal. Between your insults (that I regret reacting to...once), your lack of reading comprehension and inability to spell or use spellcheck...eh...I'm done.

I will, however, clear the air and paste my comments, in order, followed by yours. The story tells itself. Took me all of 5 minutes, including the html.

SunkenCiv: I'm done. Sorry your thread got poisoned; my apologies. I can let it go (and will). It really WAS an amusing observation of mine and merits further discussion, imho.

My comments of 'substance', quoted directly, in order:

Based on the fact that the rest of the world’s humans of the past are decidedly ‘different’ than ‘Africans’... ...perhaps they migrated out of Africa for much more mundane reasons.

The climate wasn’t like that until long after the migration began.
What I find amusing about so-called ‘scientific’ research about the ‘migration out of Africa’ is that it ignores, ostensibly for PC reasons, the fact that those that migrated were decidedly ‘different’ than those who remained.

So where did whites come from? Spontaneous albinism?
It’s just an amusing observation of mine that whites were alien to Africans when they ‘rediscovered Africa’...there’s probably some basis of fact to this, but who would actually fund a study of ancient reverse racism? A study that almost certainly would conclude that whites were cast out of Africa, not ‘migrated’...likely demonstrating that racism is rooted in those of color, not the converse. That study just ain’t happenin’...

Can’t take a joke, can ya? I was mocking the irrational racists and it went right over your head. There is a bit of truth to my mocking, however. There’s nothing irrational about observing that Africa was populated by ‘Africans’ before the Europeans went back.
The only thing irrational is inserting bias into an exchange and labeling my view ‘irrational’...and tossing juvenile insults.
Maybe you can put aside your own bias for a few and read something more academic than your own vague & vulgar reference

Wow. G’day!!

Your words: "I’ve tried to find something printed that backs this up. I found one but it was a Redneck, Religous, Racist sight and was very crudely written. In other words, that website does not like the scientific evidence put in front of them....
Maybe you should read that website I stumbled on. More your speed, I think."
Ramrod it, sphincter.
I was mocking the faux racists of the world and the 'out of africa' theory and you devolved this into something else.
I must've hit a nerve...

I did hit a nerve...

I was elaborating for a simpleton. ROFLMAO

‘Simpleton’ pretty much nailed it...

I did hit a nerve...

You ‘argue’ like many liberals. Telling.

Your responses, quoted directly, in order:

What is your source? I’ve tried to find something printed that backs this up. I found one but it was a Redneck, Religous, Racist sight and was very crudely written. In other words, that website does not like the scientific evidence put in front of them....

Wow. Here I thought I was having a rational discussion.
As far as why white people are white, then you are actually closer with your statement “Spontanious albinism”. Humans have an amount of Melanin Pigment in our system. It protects us from the Suns radioactive Rays. The closer you are to the equator, the more melanin. As we scattered away from that area of Africa, we did not need as much melanin and it decreased making us whiter. This is actually simple science that was proven long before they discussed everyone coming from Africa. Maybe you should read that website I stumbled on. More your speed, I think.

You are truly something else.... Not only did your “joke” go way over my head, every single post you’ve made has been a confusing mess. You say I have an irrational bias. You mention that I left a vague and vulgar message about melanin.
Let’s break this down. You started your post with the statement, “ the fact that the rest of the world’s humans of the past are decidedly ‘different’ than ‘Africans’...”
You followed that up with a Scientific Fact that again, Africans are different than us. (There’s a trend here. We can’t be African....)
I asked a simple question about where this research came from and you obtusely answered “So where did whites come from? Spontaneous albinism?”.
This is where it gets interesting because this is where you say I was being vulgar and vague. That’s the real joke here, isn’t it? While you go off on not wanting anything to do with having the slightest possibility of African heritage in you and mentioning in three threads some off the wall thing about reverse racism... from the time of CAVEMEN, I explained to you how Melanin works in the human body. Nothing vulgar. Nothing vague. Just a literal scientific fact about your word play “Spontaneous Allbinism”.
I do understand your point though. It rings loud and clear. Africans are different than anyone else on the planet. You mentioned that more than once. Got it.
Oh, your link was truly an interesting read. I might look deeper into this subject. I don’t know that it actually discounts any of the other theories but it was very interesting and thought provoking.
Unless I find out that we are direct descendants from Mars or some other planet, I can honestly say that I couldn’t care any less as to the location that the human race began.

Yep. Good call. Bail.

Haaa!!!
You do make me laugh.
Hit a nerve? No. Not at all. Just found your ramblings humorous.
“I was mocking the faux racists of the world and the ‘out of africa’ theory and you devolved this into something else.”.
Nope. Your first two post had nothing to do with faux racisism. It, quite literally was you stating that Africans are different than the rest of us. Actually, if you read my post I sent above, it pretty much gives a timeline of your post. Don’t have time or the desire to retype or in your case, reinvent history.

Nope. Just showed you for what you are. That’s all. Enjoyed watching you divert and squirm though. Found it quite humorous.

That actually makes no sence at all. Literally none. This is like speaking to someone who is either half in the bag or someone with clinical ADD. You have trouble following your own post as well as post to you. Just all over the place.
It’s okay though. You’ve made me smile more than once today.
Between the “Lol”’s, “Rofl”’s, “G’day” and other teenage phrases that you toss about, I have had quite a few laughs. Thank you for that. Enjoy your evening!

Okay. You posted twice. Put down the bottle and move on. You sound like a sad, bored, little, old man.

Sad, Bored, Juvenille, little old man.

Oh you! You silly little racist girl! You make me laugh so early in the morning!

You pose quite an argument. You really do. Repeating yourself constantly. I’m assuming it is so you can have the last word. I’ll let you have that for a while as I have to go to work! Enjoy your day!

Elaborate. How do I argue like a liberal? Typically, I see that comment posted on FR every single time someone gets angry. Or as you repeated over and over and over, “hits a nerve”. It is Sort of the go to comment.
That being said, you are way off the mark. In more than one way. I’m not a liberal. Nowhere near. Secondly, I wasn’t arguing. You took the conversation to a truly childish level and I joined in. Found it humorous. Looked forward to turning FR on this morning to see what nonsense you responded with. Was not disappointed. Had a big smile. Drank my coffee and headed to a breakfast meeting with a smile on my face.

You began the exchange with recommending, in your words, "Redneck, Religous, Racist sight and was very crudely written..." site was "...more your speed..." in response to my statement, "A study that almost certainly would conclude that whites were cast out of Africa, not ‘migrated’...likely demonstrating that racism is rooted in those of color, not the converse.".

I should've let it go at that point. But I am now...
