Ice Age Survivors Found In Iceland
Science Daily — Many scientists believe that the ice ages exterminated all life on land and in freshwater in large parts of the Northern Hemisphere, especially on ocean islands such as Iceland.

Scientists at Holar University College and the University of Iceland have challenged that belief, at least when looking at groundwater animals. They have discovered two species of groundwater amphipods in Iceland that are the only animals species found solely in Iceland.
"These finding can only be explained by these animals surviving glaciations in some kind of refugium under the glaciers," says Bjarni K. Kristjánsson, the scientist who found the species.
In an article in the August issue of The American Naturalist, they put forward strong support for their theory. "Groundwater amphipods are poor at dispersal, and can not be transported with birds or humans," says Jörundur Svavarsson.
One of these new species falls within a new family of amphipods, which indicates that the species has been a long time in Iceland. "The time since the end of the last glaciation is not enough for a family to evolve," says Svavarsson. Kristjansson and Svavarsson find it likely that the amphipod came to Iceland as early as 30-40 million years ago, when the volcanic island was being formed. "If our theory is right, we have discovered the oldest inhabitants of Iceland, and that can help us further understand how Iceland was formed," says Kristjansson.

Shoot, I was hoping for some interviews.

This is nothing, the title made it sound like they found people.
Really, I was all excited thinking we could ask them about climate change since they would have some real insight!

Thank you for posting these interesting items so faithfully! You find such interesting things. I rarely post, but I always read your threads.
The death of logic...
LOL! I love those movies. :)
It could be that one or more lakes remained unfrozen during the Ice Age (or the last Ice Age for Macroevolutionists).

I second that!
We are all Ice Age survivors.
I third that.

I’m pretty sure I’ve survived an Ice Age. At least I was told in 4th grade (late 70’s) that there would be another Ice Age by 2000. Still here.
Um, wait a sec. Aren’t the people of iceland actually survivors of the (little) ice age?
I wonder if they taste good.
Can they be breaded and deep fried?
Evolutionists are fond of telling stories as if they were factual!
They're probably very small. The northern tier of the US states have a similar critter on their shallow lake bottoms, but only in a grayish-green color. I suspect this white one swims upside-down as well.
Surviving an ice age is nothing. We do it every year here in NY.
I'm having difficulty scanning the logic of this sentence. Can anyone explain it to me?
Thanks for the ping, editor-surveyor!
Tell Al Gore to stick this!
Thanks for the ping!
LOLOL! It doesn’t make sense to me either.

Why soytenly- lemme just put on me apologetics cap... K ready:
You see, long long ago, when a species didn’t really fit into any category because, well, frankly, there wasn’t anyone around to classify them, they were not technically a species. Then, when modern man leapt from the trees and hit the keyboards, he done thunk “We gotsta classify stuff” and so He did, mistakenly thinking all species had common anscestry. So, now that we’ve uncovered this ‘new species’ which wasn’t classified before, we’ve done classified it, thus giving it a grandfathered status of and distinction of being an actual species way back when when nobody was around to classify species. So, if you think about it, the new species really was around for a long time— it’s just that it’s...errr... new to us now...in a manner of speaking.
Yuck- I’d rather study ice-crickets
N.Y? We used to travel south during hte winter to N.Y just to warm up for the winter- N.Y was our winter florida sunshine :)

[[These fish, which are popular in aquariums, are deep-bodied and have one nostril, rather than the usual two, on each side of the head.]]
The reason they only have one nostril is because as they evolved from land dwelling critters to fishies, they lost their fingers on one side and couldn’t pick their nose with that side’s fingers anymore, so eventually they lost their nostril too
Is this where those cavemen from the Geico commercials came from?
I know I am, considering I survived my first wife.
Evidence continues to accumulate that life of some kind can survive almost anywhere.
When we get out and start exploring the solar system in a really big way in the next few hundred years, I wouldn't be surprised at all if we found life in several places off our planet.
Is it my computer or is your link “Evolution in Your Face” really meant to take me to Penthouse magazine?
Ah, here’s a working link:

No problem, thought I might of been infected.
No one appreciates a visit from the STD florist... ;’)
Evolution in Your FaceLake Victoria, Africa's largest lake, is home to more than 300 species of cichlids. These fish, which are popular in aquariums, are deep-bodied and have one nostril, rather than the usual two, on each side of the head. Seismic profiles and cores of the lake taken by a team headed by Thomas C. Johnson of the University of Minnesota, reveal that the lake dried up completely about 12,400 years ago. This means that the rate of speciation of cichlid fishes has been extremely rapid: something on average of one new species every 40 years!

OmniFossils Show Corals Survived Past WarmingA critical reef-building coral that has been thought especially vulnerable to global warming of seas may not be so frail after all... The corals living from 7,300 to 9,500 years ago show geological evidence of enduring severe storms, salinity changes and temperature changes without any noticeable ill effects.

Fairy shrimp hatched from eggs collected at the bottom of former water wells in Saudi Arabia.
meanwhile, in the ANTARCTIC:
http://www.meta-religion.com/Zoology/New_species/antarctic_ice.htm
Among the hundreds of specimens collected, the scientists identified 15 possible new species of shrimp-like amphipods, and four possible new species of cnidarians, organisms related to coral, jellyfish and sea anemones, the scientists said in a statement.
These specimens will be analyzed to determine whether they in fact are newly discovered species.

Enough monkeys with typewriters might eventually produce a RAP Song.. but monkeys seem to be smarter than that..
Fairy shrimp? They couldn’t even find some hetero shrimp? Commies.
There’s also some real hot water in Iceland, which is parked over a heating grate.
