Scientists clone long-dead animal

Found this pretty interesting. I had no idea that they have been keeping frozen cells of extinct/endangered animals since the 70s. Sounds pretty promising considering how fast species are disappearing.

Astounding even veterans of the fight against animal extinction, cloning technology has reproduced two endangered wild cattle bulls, each born to dairy cows last week on an Iowa farm.

The procedure that created the bantengs has given animal conservationists hope that cross-species breeding can help reverse the daily disappearance of 100 living species and add genetic diversity to dwindling animal populations.

cool.

i think they shoud clone the Dodo bird. and bring it back. id love to see oen of thoes things walking around

since it's been extinct for quite a long time, i dont think they have any dna of it.

Yes, it was discovered around 1600 by explorers I believe, and then was extinct 80 years later from habitat destruction, the introduction of new species to the island (which killed off all their nests), and just hunting them cause apparently they tasted good.

This isn't a really big breakthrough. Cloning has used DNA from long passed specimens with moderate results. What I bring up though is that like 2 years ago scientists did the same thing with a yak or something and it didn't live longer than a year. You have to remember that this animal is already aged to whatever the original was, so its lifespan is considerably shorter. This is one of the biggest reasons why human cloning is (or at least by most serious scientists) not acceptable. This is also why we want to be able to use embryonic tissues in our research.
 
" so its lifespan is considerably shorter."

Yes, but some day they will find a way too extend the telomeres (what is believed to be one of the big factors in "DNA aging") and that won't be a problem anyomre.

I'd like to see a list of the 100 species that are going extinct every day. I've searched and have not found this 'list', but I have found many people claiming many different numbers. Sounds like someone has been smoking the wacky tobacci.

If they can do this, they can stop the key mechanism of aging. Dont hold your breath though. IF it can be done, then repairing cells during the cloning process might be feasible. Repairing ALL the cells of a fully developed human would be quite a trick.

wouldn't this be solved by simply breeding the animals that you cloned? So long as they're virile, wouldn't the newborn be, "like new, in box"...to use rossman terminology. You're not the age that your parents were when they made you.
 
"Repairing ALL the cells of a fully developed human would be quite a trick."

Understood, but I assumed we were just talking about the DNA from one nucleus that would be used to make the clone.
