The four clones from the same cell line as Dolly the Sheep
❝ Dolly the Sheep started her life in a test tube in 1996 and died just six years later. When she was only a year old, there was evidence that she might have been physically older. At five, she was diagnosed with osteoarthritis. And at six, a CT scan revealed tumors growing in her lungs, likely the result of an incurable infectious disease. Rather than let Dolly suffer, the vets put her to rest.
Poor Dolly never stood a chance. Or did she?
❝ Meet Daisy, Diana, Debbie and Denise. “They’re old ladies. They’re very healthy for their age,” said Kevin Sinclair, a developmental biologist who, with his colleagues at the University of Nottingham in Britain, has answered a longstanding question about whether cloned animals like Dolly age prematurely.
❝ In a study published Tuesday in Nature Communications, the scientists tested these four sheep, created from the same cell line as Dolly, and nine other cloned sheep, finding that, contrary to popular belief, cloned animals appear to age normally…
Dolly’s birth, 20 years ago this month, blew the world away. Scientists had taken a single adult cell from a sheep’s udder, implanted it into an egg cell that had been stripped of its own DNA, and successfully created a living, breathing animal almost genetically identical to its donor.
Now, based on results of this new study, researchers have confirmed what most scientists believed years ago: Cloning does not lead to premature aging.
❝ Many scientists hope that changes in perception will lead to advances in reproductive technology that will enable us to provide food for a growing global population, save endangered species and develop advanced therapies…Even then, welfare and ethical concerns will remain.
Some of those concerns are legitimate and should be the focus of scientific study. Most are crap grounded thoroughly in ignorance and fear.
In my reading, most of the self-titled scientific ethicists have little to do with science or ethics. They are religious moralists at root and dedicated to raising so-called concerns rooted in superstititon and retribution from their g_d.
Meanwhile, virtually all the laws governing clone research persist – even though they are about as legit as, say, laying on hands to raise the dead.
