#5: Dolly the Sheep Made History
Top 10 Songs You Didn't Know Were Written By Dolly Parton
Mary had a little lamb, but we cloned one. Dolly was the very first mammal cloned from adult cells. Scottish researchers took a somatic cell from the mammary glands of one adult sheep, fused them to unfertilized egg cells from another sheep, and implanted the cloned embryo into one more sheep. It took 277 tries, but in 1996, Dolly the sheep–named after Dolly Parton– was brought into the world. Dolly proved that with the right cells, you can successfully clone an adult mammal. Sadly, Dolly only lived for six years; but her legacy will live on forever.
#4: There Is Hope in Cloning Extinct Animals
Top 20 Extinct Animals
This has gotta be the holy grail of genetics. Even as we speak, scientists are working on cloning a Woolly Mammoth, using tissue samples from a well-preserved carcass found in Siberia. Believe it or not, scientists actually succeeded in cloning an extinct animal before: the Pyrenean ibex –extinct since 2000. Using the last ibex’s frozen cells, scientists tried the same technique used to create Dolly, and a surrogate mother of a similar species. The process was a qualified success… the clone died minutes after birth due to lung defects. The experiment may not have ended well, but it did show that there is hope for species de-extinction.
#3: A South Korean Lab Will Clone Your Pet
Top 100 Facts About South Park
Okay, your shih tzu just died. Do not put her in the freezer with the corn dogs. Instead, wrap her up in wet bath towels and put her in the fridge, next to the hot dogs. You now have five days to get a vet to extract some tissue samples and ship them off to Seoul, South Korea where Sooam Biotech will make you a shih tzu #2. However, it’s going to cost you about $100,000 USD, plus that bath towel, cuz you’re never using that again. Also, while your clone puppy may look like your old pal, there’s no guarantee that it will behave like the original… so you could be paying 100 grand for a blank canvas.
#2: The First Animal Ever Cloned Was a Sea Urchin
Top 10 Animal Facts to Make You Sound Smarter
That famous sheep may have been the first animal cloned from adult cells, but technically the first animal ever to be cloned was a sea urchin way back in the 1880’s. German biologist Hans Driesch experimented on a two-celled sea urchin embryo by dividing it into two embryonic cells. He expected them to create two halves of one sea urchin. What he got instead was two complete and separate sea urchins! Was it a fluke? Not really. This experiment showed that each cell in the embryo has its own set of genetic instructions, and can turn into a full organism, as in the case of twins. In fact, some argue that Driesch wasn’t actually cloning, but artificially twinning.
#1: Human Cloning is Widely Outlawed
Human Cloning, Penis Slaps & Seagal Training: The Dispatch Ep.6
This might come as a downer… but despite the wild claims of a few small groups, there’s no proof of cloned humans ever being created. Many countries and states make a distinction between cloning for reproductive purposes and for therapeutic purposes and create laws to restrict or prohibit one or both. People are mostly concerned with the ethical questions that human cloning raises. For instance, if you clone yourself, would you be able to steal your clone’s organs when yours falter? Or, if we really start playing with the human genome, wouldn't that open the door to eugenics? And most importantly, what would happen if you clone your clone? So, would you pay 100 grand for a clone of your dog? And what would you do if someone you don’t like started cloning themselves?
