Extinct!

Excluding the impact area, there was still quite a bit of natural selection in play. The big animals and the overly specialized animals went extinct. That's why mammals and small dinosaurs (in the form of birds) survived. They didn't rely on big food sources like the giant herbivores and carnivores of the time.

But we wouldn't be putting them in the wild. We'd have them live miserable, short lives inside a research facility.

I know that. I was just putting my own thoughts in on whether it involved natural selection or not.

If they could successfully bring an animal back, they'd need to have a limit on how many of the animal they could keep in one area to make sure they've got no mate if they ever escape.

Well I already have a short miserable life that I'm spending on SPPf, wait...

Anyway, the whole thing is dependent on whether we can get this cloning technology right. Getting perfectly complete strands of DNA is apparently only half the battle. We can barely clone sheep, we got Dolly only after 200 and something eggs had been destroyed in the process, and even then she only lived a fraction of what a normal sheep lived to be. That's with complete DNA, embyos no less. So to go from there and say, okay, now let's clone an extinct animal, from DNA that's been sitting in the ground for however many millions of years! Erm, there's going to be problems. Then again, that's not to say its impossible. It says that we don't have the current technology to accomplish such a feat. It was thought impossible to clone extinct animals because you would need the ovum of a female, but people found out you could just use a host animal. (Such as impregnating a mammoth into an elephant.) However each time we tried that the animal just dies, and again, thats if it even makes it far enough to be born in the first place.

So yeah, we don't really have a grip on things yet.
 
the problem though with cloning an extinct animal (and then putting it in the zoo as Brain says) is that its a rigourous 3 step process

1. Getting the DNA (complete)
2. Cloning the animal
3. getting said animal to adapt to todays modern enviornment, deseases, other animals etc.

so yea even if we do get to step 2 then we gotta figure out step 3.
 
Well the mammoth is only 10,000 years old, alot of its bones are not fossils. Infact the frozen remains have been good enough to eat in some occasions 0.0.

Also who says that they would live in a research facility? There has been a nature preserve built for them in an area that mimics their natural habitat.

Lastly mammoths didnt just become extinct becasue of changing climate, our ancesters had a hand in it too, and neanderthals werent much help either.
 
Hmmm, I'm naturally averse to the idea of cloning to bring extinct animals back, certainly if the only purposes would be research.

Most particularly I wouldn't be happy with animals being brought back that we had a hand in making extinct. Lessons such as the extinction of the Great Auk and the Thylacine, where humans were exploitative and bore great responsibility for their persecution, should not be forgotten. Merely recreating these creatures would be another example of human beings seeking mechanical answers to problems that could be solved merely with greater respect towards our natural resources and the world around us - something which I think is lacking more and more.

And heck, we'd be putting a lot of paleontologists out of business, and we can't have that now!

Do you seriously think that you can accomplish something by bringing the dinosaurs back to the land of the living?

I just think that bringing them back is just about as close to an insane idea as you can get it, & even so, that person must be really drugged up in order to come up with that.

In all seriousness, the only thing that dinosaurs will bring with us is one hell of an adrenaline sport, & I dread to see this happening now.

Dont you mean, extinct? :p

Yes I do agree that the actions of certain humans is something we should never forget. But some animals such as the Thylacine or dodo deserve a second chance, their extinction was unatural and satisfied nothing but the greed of certain humans.

Umm, nobody mentioned dinosaurs. They are not only impossible to clone as any little DNA found is fractured and irepairable, but also there would be no space for them, laboratory or in nature.

Also, after the jurassic park film I think most scientists are rather put off of the idea. :p
 
I can't imagine a big 60 foot or so t-rex in a zoo. Imagine how much it would take to feed and how hard it would be to look after?

And dodos would probably kill them selves again and you would probably need to keep the mammoths in Siberia.
 
Also, if we were to bring a extinct animal back to life we would then have to take care of them. Right now we are having a hard time with pollution, from sewage waste or what else have you. Having the giant animals going bathroom, where are we gonna put the waste? It would infect the ground water in the zone of saturation. Then we would need to clean and filter the water, which is not cheap.
 
I agree with it, as long as we don't accidentally revive dangerous animals, future zoo attractions (they should be animals that were made extinct by humans, not money-making T-Rexes), deadly viruses from millions of years ago, and stuff.

I just feel so bad reading about extinct and endangered animals, and I feel like we should be doing more.

You are aware that the animals we have now shit as well right?
 
i would have thought twice before something like this would be brought up as a project, it will have a major impact on the ecosystem, they arn't very scial too, i don't wanna get eaten leave me alone!!!
 
Recently a 6month old baby mammoth has been discoverd in Siberia, with anotherr estimated 1 million frozen mammaths estimated yet to be found. So far, about 80% of the mammoth genome has been sequenced. I believe that the ability to clone a full sized mammoth will be available with 30-50 years, probably by impregnating an Indian Elephant with sperm from a frozen mammoth. It will be easy to recreate the envirement of these beasts, probably in areas like siberia where parks have already been set up for them. They lived until about 8,000 years ago in the mainland and survibed until 1750 BC off a small island in the east coast of russia, so the DNA samples are relatively recent and usable, especially if they were frozen (my biology teacher was teling us about some samples of mammaoth meat were still fresh enough to be eaten).

It's not like scientists would clone T. rexes and release them into the wild. It would likely be cloning something FAR more recent, like the mammoth or dodo, and keeping them in a research preserve.

I doubt we'd see un-extinct creatures in zoos for a loooooooong time. Most likely their corpses in traveling museum exhibits (similar to King Tut or that creepy Bodies exhibit).
 
I've always wanted to see what a real live Dodo was like, though I'd really like to see all the giant ancestors of animals.

The dodos didn't kill themselves. The Dutch did (after likening their fatness with the bosoms of women, who they were deprived of).

Unfortunately though, the only remains of the dodo is the head, since they burned the rest of its body after it had started to rot. I doubt the dodo could be cloned from actual dodo DNA.

One argument that does make sense for not bring them back is if they carried a strain of some unknown virus that existed thousands, or millions of years of ago. Imagine, if a disease that existed ages ago, was re-introduced to todays world. We'd have no immunity. It makes for a very nasty situation.

This can be avoided by making sure the first few specimens are in a quarantined area. They can make a large area and have it mimic the environment of the Mammoth or the Dodo or whatever in the Nevada Desert (like where they have those other facilities). After having at least a few alive of each gender, making sure there are no abnormalities, they'll let them breed, and after a couple generations, assuming nothing goes wrong, have them finally put into Zoo's and other places.
I know there are plenty of problems with my idea, but something like that could be done.
