Mammoths may roam again after 27,000 years
Times UK ^ | 8/15/06 | Times UK

Posted on 08/15/2006 10:23:52 AM PDT by freedom44

BODIES of extinct Ice Age mammals, such as woolly mammoths, that have been frozen in permafrost for thousands of years may contain viable sperm that could be used to bring them back from the dead, scientists said yesterday. Research has indicated that mammalian sperm can survive being frozen for much longer than was previously thought, suggesting that it could potentially be recovered from species that have died out.

Several well-preserved mammoth carcasses have been found in the permafrost of Siberia, and scientists estimate that there could be millions more.

Last year a Canadian team demonstrated that it was possible to extract DNA from the specimens, and announced the sequencing of about 1 per cent of the genome of a mammoth that died about 27,000 years ago.

With access to the mammoth’s genetic code, and with frozen sperm recovered from testes, it may be possible to resurrect an animal that is very similar to a mammoth.

The mammoth is a close genetic cousin of the modern Asian elephant, and scientists think that the two may be capable of interbreeding.

The frozen mammoth sperm could be injected into elephant eggs, producing offspring that would be 50 per cent mammoth.

The suggestion that it may be possible to recreate an animal that is at least part-mammoth has emerged from a study of mice by Japanese, British and American scientists.

While many types of mammalian sperm, including that of humans, can be preserved by freezing, mouse sperm is vulnerable to damage that can limit its ability to fertilise eggs when it is thawed.

A team led by Narumi Ogonuki of the Institute of Physical and Chemical Research Bioresource Centre in Tsukuba, central Japan, has demonstrated that sperm better survives freezing if testes, or whole mouse bodies, are frozen.

Even sperm taken from mouse bodies that had been frozen 15 years ago was capable of fertilising mouse eggs and producing pups, the researchers found.

The work has technical implications for the breeding of laboratory mice for medical research, but it also shows in principle that mammalian sperm can survive in a body that has been frozen for several years.

This could mean that it is able to survive in similar fashion over much longer periods, as in mammoths frozen in permafrost.

“Restoration of extinct species could be possible if male individuals are found in permafrost,” Dr Ogonuki said.

“If sperm of extinct mammalian species, for example the woolly mammoth, can be retrieved from animal bodies that were kept frozen for millions of years in permanent frost, live animals might be restored by injecting them into oocytes [eggs] from females of closely related species.”

Looks like this article is going to roam again after just a few hours.

They could have success if they were to artificially insemenate Rosie O'Donnell with the extinct Mammoth's DNA, no?

Sounds like a necrophiliac's excuse.

If "they" really want a Frankenstein creature they will take some of that wooly mammoth sperm and mate it with a Hillary Clinton or Helen Thomas clone ....... now THAT would be a monstrosity for the ages!!

Our luck they will put them in Alaska and tell us we can't drill for oil or we will spoil their traditional breeding grounds. I wonder what Mammoth steaks taste like? Which gun would you use to bring down a Mammoth? Are Mammoths on the endangered species list since they are technically extinct? Is there a new category of endangered called technically endangered? So many questions......

What would be the point of you getting out of bed in the morning? Have you done all you could do to wipe out disease and hunger? Unless you're Mother Teresa, you don't have the standing to make such criticism.

This kind of research, in addition to being interesting for its own sake, might lead to techniques that benefit mankind. Treating infertility for example.

I bet it tastes a lot like spotted owl or white rhino.

Unadulterated BS. Freezing sperm for 15 years is not the same as sperm frozen for 27,000 years without cryopreservatives and inconsistant temperatures. The DNA will be too fragmented to fertilize anything.

Curing disease and eliminating all hunger aren't prerequisites to scientific experimentation - thankfully, since no science would ever have been done in that case.

I have no interest in the diseased and hungry. I am not a compassionate conservative.
