"An abrupt and dramatic climate cooling of 8°C in 200,000 years forced the extinction of tundra plants and insects and brought interior Antarctica into a perpetual deep-freeze from which it has never emerged, though may do again as a result of climate change."

This story kicks butt... I don't care, it's awesome. Global Warming rules!

[bbqpenguin]

correct me if i'm wrong, because god knows it wont be the first time if global warming is thawing out a place that use to be habitable, doesn't that mean the earth was once considerably warmer than it is now? that is, if that tundra wildlife was essentially frozen solid, that means that antarctica was once (relatively) warm, right? so what the hell happened? if there was a 200,000 thousand year cooling period, then is global warming a disaster waiting to kill us all, or just a return to what was once 'normal'?

[Skittles!]

You forget, bbqpenguin, that all the land masses were once connected, and so Antarctica would not be in the South Pole as it is today. That would explain why Antarctica had life on it and then got frozen over.

Eh, I think Antarctica was pretty far south by 14 million years ago. The most obvious point to be made would be that 8 degrees had quite an effect. And that was over 200,000 years. Nah, a little warmth won't hurt anyone.

I dono. The Indian sub-continent used to be part of the Southern Hemisphere, like way down near southern Africa, and it's still moving northwards. What's to say that Antarctica wasn't more northern than it is southern today?

The issue is the rate of change. Scientists can find no instance in the geologic record in which the change in climate was as rapid as it is today. It is too rapid for plants and animals to adjust through the evolutionary process. Thus, even though there may have been periods with warmer overall temperatures, they developed over much longer periods of time.

I have no doubt that it was. But I don't think it could move that far in such a short time. I'm pretty sure it looked something like this.



That's pretty close to the antarctic circle. It might have been like the weather in Northern Canada (or whatever location might be more familiar for our non-northern hemisphere biased people... southern South America?), but I imagine it was still pretty cold.

I'm still totally impressed with that picture.

I second that.

I second that.

It's a shame it's completely wrong though.
Someone hasn't done their research....

Psh. I bet you can't draw a better one.

You forgot that the world was still in the Pangea when humans started making tribes. Even though the were extremly primitave, humans managed to move from where they orginated through asian to North America, and stayed their until the continents shifted.

[Neoteny]

Nooo... Pangaea went through its major breakup phases at about 60-65 mya. That's way before we were around making tribes and fucking shit up like we do.

Then how did thwy get to other continents? Boats? The first was created was 9000 years ago.

Perhaps in few places. Africa and Asia were connected, which was connected to Europe. Asia was also connected to North America by the Bering land bridge.

Get hold of last month's Scientific American if you're interested in this subject.

What do you mean Asia and Africa were connected?
They still are you ponce!

What planet are you living on today? Zog?

[Skittles!]

Aboriginals were meant to of come over from Asia to Australia about 60,000 years ago. BUT there seems to be a theory that other humans before that lived on the Australian continent before that. So y'know..

HELLO! Has anyone heard of PLANET X!

Get off my sack! They were then, so my statements stands!

THere are a lot of good theories being tossed around today. My favorite is that Asia is the cradle of life.

[mpjh]

The DNA evidence shows that all people originated in Eastern Africa and moved out from there. However, there some thought that the pre-human apes moved out of Africa to colder climates and then came back before evolving into us,

I read something about a stone 'axe' that was found in Asia that is older than any found anywhere. Lots of extremely( and almost too) old stuff has been popping up in Asia.

[mpjh]

This may just mean that more and earlier migration occurred than some thought. The DNA evidence is that the original people would have the most diverse DNA variations and that all others would have less diverse DNA variations and would have an evolutionary trail of modifications to the original DNA. So far the evidence is that Africans from Eastern Africa have the most diverse DNA and are probably the region of the original people.

I don't know that I am using the correct terms, but can get them if necessary.
