Most of Woolly Mammoth Genome Reconstructed
geekmansworld writes "From the Washington Post, 'An international team of scientists has reconstructed more than three-quarters of the genome of the woolly mammoth using DNA extracted from balls of hair, the first time this has been accomplished for an extinct species.' Who wants a pet mammoth?"
Given that they have yet to work out how many chromosomes the woolly mammoth had, or which of the DNA features are genuine mutations, and which are artefacts caused by damage since the death of the creatures from whom DNA was extracted, there's a fair distance to go yet.
Still, I don't doubt this is a seriously fun project to be working on. I'd love to get involved.

It could be the solution of how how to maintain legacy systems in generations to come. They just need to start mapping the genes of a COBOL programmer.
My understanding is that the woolly mammoth is one of the first casualty of the infestation Earth by the human species : they went extinct partly because of the warming climate, partly because of overhunting.
There are no stupid questions. But there are stupid places to ask them. Try elsewhere, for better sources of information.
May the Maths Be with you!
Not to mention, didn't we also have this story about how the proteins affect the transcription too, and the same piece of DNA can be transcribed in a dozen different ways or not at all, depending on how those proteins regulate it? It seems to me like in that case it's like saying they decoded half of it.

You want us all to read a book/anthology just to get one joke? /Shakes head/ Only on slashdot...

right NOW, we can do this
apparently it would be tedious, but a number of technical hurdles have been overcome lately to the point where this is really conceivable to do, and the talk about doing it isnot theoretical, but practical
1. most recent modern genome decoders don't care that the dna is shredded into pieces
2. encapsulated in keratin (hair), the dna is not so tainted by bacterial dna like it is in bone
3. a new technique allows modifying modern elephant dna 50,000 genomic sites at a time, rather than one by one, so the proper egg can be arrived at after a few generations of reconstruction, implanted in a female elephant, and voila
this can be done, right NOW!
amazing
even more freaky: we can do the same, right now, with neanderthal!
using chimpanzee as a starting point for ethical considerations, we can also, right NOW, bring a neanderthal back to life
that's pretty freaky. these guys wouldn't be dumb. someone would have to explain to the guy that he is not the last of his species, he's an artifically reconstructed clone of a guy who died 50,000 years ago. no one of his kind exists anymore
but we revived a wooly old friend of yours too. here's a spear, happy hunting
just don't eat the dodo
or the quagga
or the irish elk
or the auroch
or the sabretooth though
really really freaky and amazing

Dinosaurs died out 65 million years ago. Mammoths became extinct about 10,000 years ago, though some scientists believe that there were still pockets of mammoth populations on isolated islands as late as 3500 years ago.

My blog
Really? Considering the amount of SEO spam that's corrupted Google search results, considering the cabals, corruption and low quality of most wikipedia results, and considering that many of the world's experts on most science and technology fields ARE regularly reading slashdot, then I seriously doubt there IS ANY better place to ask a science related question than on this site.
Of course, the downside is that there are some grumpy, elitist pedants here.
They were quite recent: They survived on Wrangle Island (Artic) and St Paul Island (Bearing Sea) as dwarfs until 1700 BCE.
They were also found on the Channel Islands off California and disappeared around 40,000 BCE. They are still digging them up, preserved, in the permafrost of Siberia.
Humans did hunt mammoths, sabre-tooths etc.
Don't be apathetic. Procrastinate!
Crocodilians do not come from dinosaurs, although they are related, i.e. their earliest common ancestor was neither a dinosaur nor a crocodilian. On the other hand, the earliest common ancestor of birds was a dinosaur.
Also, mammals existed at least 125Mya:
The oldest known marsupial is Sinodelphys, found in 125M-year old early Cretaceous shale in China's northeastern Liaoning Province. The fossil is nearly complete and includes tufts of fur and imprints of soft tissues.
I don't think you understand. The internet and slashdot was an elaborate ploy by Nivens to get more fans. He planted the ideas for the internet a long time ago and nurtured it until the web was born. He then planted the idea to create a forum for nerds. Once this was done he waited for critical mass and posted this line. Now people like me who stopped reading fiction some time ago, will see this name and investigate on the very same internet! Its rather brilliant. The only thing is that if we comply and read, then he will no longer have a use for the internet and will likely have it taken down (his purpose being completed). To prevent the destruction of this invaluable tool, I will boycott reading any further.
and with my first paranoid rant done, I am ready to start my day!
When all else fails, try.
>Well the placental mammals, like us and almost every other mammal, did not evolve until after the Asteroid event.
Wrong. There were plenty of mammals in the Mesozoic. And according to the University of California Museum of Paleontology "Eutherians first became common in central Asia during the Upper Cretaceous." Eutherians being the technically correct name for placental mammals.
