blike Posted February 6, 2003 Share Posted February 6, 2003 Do you guys think bringing back extinct species is a good idea, or bad idea. Personally, I think its a good idea, as long as its limited and controlled. I can't say that I'm for repopulating africa with extinct species. There's a reason they went extinct, and bringing them back could disrupt the ecosystem. As long as we're not reviving some form of ultra immune deadly bacteria, i'm all for it.

blike Posted February 6, 2003 Author Share Posted February 6, 2003 Oh, and populating an island with man-eating dinosaurs is a bad idea too Link to comment Share on other sites More sharing options...
PogoC7 Posted February 6, 2003 Share Posted February 6, 2003 It could be a sport. If you think your a real hunter. Go hunt dinosaurs and not kill helpless animals. Good idea with some, but they only have the mammoth, unless were talking about recently extinct. I think one day we will have too bring some back. Like the tiger, eagle (ofcourse, It will be U.S. law) and other animals who might be extinct in a hundred years. Link to comment Share on other sites More sharing options...

aman Posted February 6, 2003 Share Posted February 6, 2003 I'd like to see a dodo in a zoo, even though they were nasty mean birds that tasted like shit. We couldn't reintroduce them to micronesia since their habitat is no olnger suitable. There still is the head of a dodo in a museum somewhere that has skin on it and bones with DNA. I think it would be great if some of the bones from the LaBrea Tar Pits in California had usefull DNA. Mammoths and Smilodons would be great to see.

Giles Posted February 6, 2003 Share Posted February 6, 2003 I'm asuming you're not talking of very recently extinct species. taking genetic samples of populations wiped out by man so they can be recreated seems wise, but it might become an excuse for not conserving them now. Pogo, reintroducing a species to an existing ecosystem isn't always a good idea even if it works, and rebuilding an entire ecosystem from scratch would be impossible (for now). The critters would be in zoos. Also, you'd need a lot of samples to create a wild breeding population instead of lots of clones. genomics is going so fast that i doubt we'd learn much evolutionary history that we didn't already know. In short, i think it's pointless for now, but it would benefit whoever did it. Link to comment Share on other sites More sharing options...
blike Posted February 7, 2003 Author Share Posted February 7, 2003 In short, i think it's pointless for now, but it would benefit whoever did it. There's always something to be learned; whether it be mating patterns, eating habits, vocalizations... ...though how much of this is learned by experience with a mother. Perhaps a mammoth raised by elephants would behave more like an elephant, than an ancient mammoth. Link to comment Share on other sites More sharing options...
Giles Posted February 7, 2003 Share Posted February 7, 2003 hmmm i'm not sure we need to go so far as bringing back extinct species to do that, considering how many we have available already. Link to comment Share on other sites More sharing options...
RED FIRE COW Posted February 7, 2003 Share Posted February 7, 2003 Pretty soon we are gonna have to bring back the sharks, specialy the great white. The number of great whites has dropped dramatically 86% since the eighties. Link to comment Share on other sites More sharing options...
Skye Posted February 7, 2003 Share Posted February 7, 2003 Well the main problem is getting a full genome in working order. The DNA in samples taken from skin or fur in a museum are all broken up into little fragments, so piecing it all together will take a long time and you really need a close living relative to compare it to. After you have the nuclear DNA you can insert it into an egg like dolly was cloned...but dinosaur and extinct bird eggs don't spring out of nowhere, and mammals will need to be carried by a similar sized close relative, which will have all kinds of immune system problems. In the distant future these problems will probably be solved by research in other areas. I read a magazine article a while ago on a team here that was trying to recreate a Thylacine, a dog sized marsupial carnivore wiped out early this century. They were still in the very early stages of contructing the genome. Link to comment Share on other sites More sharing options...
PogoC7 Posted February 7, 2003 Share Posted February 7, 2003 http://www.amonline.net.au/thylacine/ ---good site about the Thylacine. It's titled Australian Thylacine: to Clone or not to Clone? I don't care, looks like it's going to the bathroom. It's ugly, but I say clone the thing. Link to comment Share on other sites More sharing options...

I can see how the "don't worry, we'll always be able to fix it afterwards" excuse might preclude conservation attempts, but surely cloning a viable population back into existence will always be more difficult than conserving one that already exists.

Skye Posted February 7, 2003 Share Posted February 7, 2003 Thanks for the link Pogo, if I weren't moving a thousand miles tomorrow I'd read into it more lol... I think the biggest ethical problem is from an ecological standpoint. The thylacine still has fairly untouched habitat it could be located in with minimal ecological impact, part of the reason it is a viable project. Many species that existed long ago no longer have any place in the world though, dinosaurs biology might make survival hard enough, but they certainly don't have a remaining ecological niche. Many species that have gone extinct would be hard to bring back unless we recreate an environment they can live in. This includes many species that have become extinct recently, by our hand.

fafalone Posted February 7, 2003 Share Posted February 7, 2003 Unless there's a undisputable link to the disappearance of a species and severe disruption of the ecosystem, the engineered species should stay confined to zoos.

Aardvark Posted February 14, 2003 Share Posted February 14, 2003 Bringing back extinct species doesnt just have to be done by cloning. A number of expeditions to Siberia have been made in an attempt to find the frozen remains of a mammoth from which frozen sperm can be extracted. The idea is to then impregnate cow elephants and through selective breeding bring back the mammoth. I think its a great idea, and to hell with any ecological disruption.

aman Posted February 20, 2003 Share Posted February 20, 2003 The sperm they freeze now they use liquid N shortly after collection. It's very fragile. It would be a very rare set of circumstances that might make this naturally possible in the arctic but I wouldn't count on it. Just aman Link to comment Share on other sites More sharing options...
