Russian Scientists Say They'll Clone a Mammoth Within 5 Years 302
Many scientists (mainly Japanese and Russian) have dreamed of cloning a mammoth over the years. When the mammoth genome was partially reconstructed in 2008, that dream seemed a bit closer. Besides the millions of dollars needed for such a project, the biggest hurdle was the lack of a good sample of mammoth DNA. That hurdle has now been cleared, thanks to the discovery of well-preserved bone marrow in a mammoth thigh bone. Russian scientist Semyon Grigoriev, acting director of the Sakha Republic's mammoth museum, and colleagues from Japan's Kinki University say that within 5 years they'll likely have a clone. From the article: "What's been missing is woolly mammoth nuclei with undamaged genes. Scientists have been on a Holy Grail-type search for such pristine nuclei since the late 1990s. Now it sounds like the missing genes may have been found."

That's an interesting question! People regularly throw around the number 40 as being the minimum number of people to keep a diverse gene pool going, could that roughly be true for mammoths too? Could they splice in enough genetic material from other partial strands of mammoth DNA to get 40 complete, but slightly different mammoths cloned and breeding? And second, where are you going to find enough space and money to house your herd of mammoth mammoths?
Re:Ice Age Park (Score:4, Informative)
"Throw around" sounds about as precise as this is. There isn't a huge amount of actual data about this.
If you look at every colonisation of any island by any species, then the minimum that is needed to start a colony is the arrival of a single pregnant female. For long-lived, slow breeding species such as humans (and elephants, and presumably mammoths), that's likely to be very dodgy on both the population genetics front, and the simple question of whether or not there are enough hands to feed enough mouths.
But in practice, that's not how things would happen. If you have a classical colonisation scenario of your beasties being caught on vegetation rafts in a flood (or on ice floes) every few decades, and carried to Terra Nova, then there's a reasonable chance of a newcomer arriving in the incipient colony every few decades. And it doesn't particularly matter if it's a male or female that arrives. That does a lot of good for population genetics.
There was a study published a few years ago of a wolf pack in southern Sweden. They're isolated from the main Finno-Russian population by a combination of tough landscape and many miles of unfriendly farmers, despite them being a protected species. The pack was, for a long time (I haven't read the paper for several years!), in pretty desperate straits genetically, with poor breeding success, and to the researchers following them were seeing a variety of diseases of in-breeding. (They could do a complete unambiguous family tree by doing DNA analyses on wolf turds, and track new pups.) The pack's size was stable at around a dozen, despite there being abundant wild(-ish) land and game for the pack to expand into. Then in the mid-90s one single solitary male (I think) wolf managed to make it through the gauntlet of central Sweden to meet up with the pack. Within a few years the pup count was rising rapidly, and the degree of consanguinity in the pups was dropping substantially. That's the effect of, literally, one incomer.
So, although 40-odd may be bandied around as a minimum safe population size, it's not a well-founded figure. It's also likely to be a decidedly different figure for different species.
Returning to the mammoth population subject : If I were planning a cloning/ breeding programme, I'd probably start by trying to clone a male. (Reasoning : the first one off the production line is going to be a "learning experience", and you really want to get your cows right for breeding from.) Then, learning lessons from "M1" and continuing genetic analysis of the raw material from new mammoth finds, I'd work on preparing my first cow : "F1".
(I've already realised that I'd have to do some careful background research to try to identify a restricted population of mammoth genetic material, in both time and space ; there's likely a lot of endemism in the populations, and mixing dissimilar genomes could cause issues. Say, one population has digestive genes optimised for grasses, while another population lived on leaves from trees ... not good to mix them, at least not while learning mammoth biology.)
Back to the population : I've now got a (probably flawed) M1 and an F1 (hopefully better). It's going to be years before F1 is fit to attempt to breed, so I'd now turn back to trying to make a better M2 (say I'm only going to get to use one elephant's uterus per year). Then F2 ; then F3 ; then F4. By now, I'll be getting close to being able to breed off F1 (I think ; IANA mammoth keeper ; then again, no-one else is), so I'd better start to attend to my stock of males. I'm making the (not unjustified) assumption that modifying male's sperm is going to be cheaper and easier than modifying eggs, so I can use more-or-less off the shelf genetic engineering techniques to bring parts of

Humans had a huge impact on Mammoths, that's well-established. The standard hunting technique for big game appears to have been to trigger a stampede off a cliff. You should also remember that humans primarily hunted Pygmy Mammoth, not the giant kind, and that humans lived right up to the ice sheet during the Ice Age (and even hunted beyond it). Neandertals and Denisovians were the primary hominids living in extremely cold climates, but modern humans were quite capable of enduring extreme climates provided some sort of food existed. (Fishing from boats turns out to have been an extremely ancient technology.)
Having said that, Mammoth diversity was dropping long before humans even reached places like the Americas, so there were clearly other factors involved.

Uh, no.
Look people like the image of the stone-age human hunter taking the huge bull mammoth down with a spear, perhaps working in groups... it's a very popular image for that reason. But it's utter nonsense. There's no hard evidence mammoths were ever hunted by humans. There is some evidence that mammoth meat was consumed by humans, which is often conflated, but scavenging food isnt the same thing as hunting. There is even some evidence that mammoths may occasionally have been killed by humans - but it was more likely an opportunistic event than a planned hunt. A small, young mammoth that happened to get cut off from its group? An isolated individual that got stuck in a bog? Sure, some of that would have happened, and humans would certainly seize the opportunity, but that's a far cry from actually going out to hunt healthy, full-grown mammoths with a stone spear.
Wooly mammoths were quite a bit larger and more dangerous than todays African elephant. And we have one and only one known case of a human group hunting African elephants without firearms. Pygmy hunters in central africa do it and have apparently done it for centuries. BUT they dont do it with stone spears - they use bows and arrows coated with a potent poison. And even so, they often lose hunters. For even a large group of humans armed with Clovis technology to attack a full grown african elephant, let alone a mammoth, would be suicidally foolish.
Elephants arent just HUGE animals, they are also quite intelligent. They are also social animals and move in groups. Another large (though much smaller) animal that also moves in groups and certainly WAS hunted at the time is the bison - but not only are even the extinct, gigantic species of bison still much smaller than a mammoth, there is a huge difference in their group behaviour. Bison are much more cow-like, and can be stampeded easily. And THIS is how they were actually hunted - whole herds were stampeded into fatal falls, then the humans went in to salvage meat and other material from the corpses afterwards. This is a much smarter tactic than trying to take one down with a spear (though also extraordinarily wasteful,) and in fact we know that is exactly how our ancestors did it. But that tactic just doesnt work on elephants.
So, no, mammoth extinction did not come at the tip of a spear. If human action helped to bring about mammoth extinction, it was not in such a direct fashion.
