. No the plants they had in their time. Plants do die off, like the many plants during the dinosuars age. Mammoths became extinct extremely recently, men were alive at the time. Some species only died out around 5000 years ago. Compared to the dinosaurs, which died out 65,500,000 years ago. yea they would still eat the same things alive today were not tlaking dinos whos food left our planet a long time ago the food is still here and the oxygen levels are the same as theywere when they were still arpound a dino couldnt live today because theres less oxygen around now then back then and we could...

Woolly mammoths, and I assume that's the species we're talking about, were Ice Age creatures. Where would they be expected to live in a world that's warming up? In 50 - 100 years there probably won't be much tundra and I don't see that keeping just 1 or 2 alive in a controlled environment would be either scientifically beneficial or ethically correct.

^Remember that they would only be hybrids (˝ mammoth, ˝ elephant). If need be, they could have their fur clipped and be put on specialized diets to lower their fat levels. It's entirely possible.

^Remember that they would only be hybrids (˝ mammoth, ˝ elephant). If need be, they could have their fur clipped and be put on specialized diets to lower their fat levels. It's entirely possible. Initially this is true, however I would assume the intent would be to create a breeding population? Some of the offspring would breed closer to the mammoth genome and so would require the more specialised habitat. Otherwise you would have to have a very expensive, continuous breeding program - perhaps entirely IVF to ensure correct hybridisation. Are you suggesting perhaps a mammoth farm? Domesticated...

Are they going to fill in the holes with frog DNA? Hahaha. This is creepy. They're supposed to be dead. TeraLink Was Here!

Some of the offspring would breed closer to the mammoth genome and so would require the more specialised habitat. Otherwise you would have to have a very expensive, continuous breeding program - perhaps entirely IVF to ensure correct hybridisation. I agree, it could be quite a difficult task. But, if they're going to be able to successfully fertilise a modern elephant using a multi-thousand year old frozen mammoth sperm cell, the idea of breeding a hybrid with (presumably) another hybrid doesn't...

Next thing you know they will be trying to bring back a dinosaur back to life "to study it". It is just wrong, they died out for a reason and should not be brought back to a world where they would be treated like guinea pigs...

The woolly mammoth could be brought back from extinction using sperm extracted from animals encased in ice. Researchers have already found that sperm taken from the frozen reproductive organs of dead mice can produce viable offspring. Writing in the journal Proceedings of the National Academy of Sciences, they suggest that sperm from frozen mammoths could be used to bring the extinct creatures back to life. The idea would be to inject mammoth sperm, assuming it could be retrieved, into the eggs of female elephants. A successful pregnancy would produce the closest thing possible to a living woo... [More]

Although I don't see how it's anymore justifiable to bring back an animal that became extinct (partly) due to human predation, than it is to revive a species that became extinct due to any other reason. They became extinct because they weren't fit for survival, just as every other currently extinct species did. You have to admit though, that we've had more than a fair impact on the extinction of some species; the mammoth included. The do do would still be alive had it not been targeted by man... not for reasons of survival, but for fashion sense. I'm just saying that just because a species is ... [More]
