"If you ran the whole experiment again, we would have woolly mammoths and no reindeer, so Santa would drag his sleigh with woolly mammoths." Paleo-geneticists are always obsessing on the old man in the sky who makes miracles happen. And they call it science.

. But there was no clear pattern to explain why the animals died off, and it proved impossible to predict from habitat or genetic diversity which species would go extinct and which would survive. Maybe "Wooly" had something to do with it.

Maybe "Wooly" had something to do with it. My thought exactly! Uncanny, eh?

"If you ran the whole experiment again, we would have woolly mammoths and no reindeer, so Santa would drag his sleigh with woolly mammoths." And ~flying~ wooly mammoths, at that. Yeesh... And you thought that ~birds~ pooping on your freshly washed car was annoying...

We find frozen woolies left and right up North. I’m sure there are a few running around labs worldwide.

One of my favorite pieces in my knife collection is a Benchmade Gold class folder, with a Damascus blade and a pure white mammoth ivory handle. Hand made, limited edition of 100.
There’s lots of mammoth ivory out there, but most is yellowish, with heavy graining and striping. This stuff is white and smooth. It’s simply breathtaking. And to think how old that ivory is... Staggering.

Researchers who studied the fate of six species of 'megafauna' over the past 50,000 years found that climate change and habitat loss were involved in many of the extinctions, with humans playing a part in some cases but not others.
I was watching a show about this the other day and they were saying that climate change was unlikely to have killed the giant armadillo. It survived for more than a million years through multiple ice ages and the wide climatic swings between the. I turn around the next day and I see a "climatologist" declaring that animals are all going to become extinct because of global warming.

Whst do we call it when an existing scientific theory is unable to explain phenemna that we know exists?
It means that the present theory is wrong.

A great many 19th c billiard balls were manufactured out of mammoth ivory. And no, I don’t have a citation for that. :’)

They went extinct because of the Occupy Ice Age jokers.

I gather that wooly mammoth were also very limited in genetic diversity.
A biological theory, the “island theory”, is that when a species are broken up on different isolated islands, they first diversify and become specialized to their individual islands, eventually becoming unique species, but are condemned to dying out because they become both over-specialized and inbred.
The same basic thing may have happened to wooly mammoths, by distance between herds.
To: dr_lew; Mike Darancette; SunkenCiv
I disagree. I think it is purely the large size. When primitive man invented the bow and arrow, all super sized meat on the hoof became easy pickins. Only in africa and india did supersized meat survive...which makes us wonder what was wrong with the humans in those two locations. In india they learned to tame the supersized animals. But in africa, it seems they just didn’t learn.
To: SunkenCiv
There is no clear pattern because the basic premise is wrong. When you figure out the question, then the pattern emerges. But if by pre-determination you have eliminated some questions, I would start there where there is no pattern.
Clues, Polar ice is thickest at the magnetic poles rather than the solar poles...
What causes water to react to magnetic fields...
How did Woolly mammoths die with flowers preserved in their stomachs... How, without digesting? Did the earths magnetic poles ever reverse... How, what could cause that?... Connect the dots.

What is the value(monetary) of a knife like that? Oh... of course it depends on the collector, but I figure it is in the vicinity of $1,500 or so.
