For now, the Neanderthal genome is an abstract string of billions of DNA letters stored in computer databases. But it naturally sparks the imagination: Could scientists use that genetic blueprint to create neo-Neanderthals in the flesh?
In the not-so-distant future, advances in genetic engineering might enable that feat, experts say. But whether such a resurrection should happen is another story.
Since the 1996 birth of Dolly the sheep, the world's first cloned mammal, scientists have greatly expanded and improved on cloning techniques. They have cloned dogs, cats, rats, pigs, and cows, among other species. In 2003, researchers in Spain were the first to bring back an extinct speciesthe Pyrenean ibex, a wild mountain goat also called a bucardothough the clone only lived for a few minutes.
All of these examples relied on a technique called nuclear transfer. Starting with an intact cell (fresh or frozen) of the animal they'd like to clone, scientists first remove the nucleus, where DNA resides, and insert it into a hollowed-out egg cell of the same or a related species. This hybrid egg is then implanted into the uterus of a female surrogate for gestation, and voilà: The surrogate gives birth to a clone.

(7,515 posts)I read that there is much more of the Neanderthal in our own genome than previously even imagined. That there must have been successful breeding between Neanderthals and Homo Sapiens. The more we learn, the less we know.

Or worse:

(7,515 posts)the article said they estimate about 17% of our genome is Neanderthal, not an insignificant number. The previous assumption was there was no interbreeding, now they know otherwise.

Just kidding, of course.
All the world's lifeforms are cousins.

(7,515 posts)I'm thinking the crew who insists the planet is only thousands of years old, will have a fit over Neanderthals... Bonobos will drive them
completely around the bend!

(7,515 posts)This isn't the article I read...but the range rings a bell. In fact, the 17% may have been the amount of the Neanderthal genome they have mapped. I need to take notes! They also found that descendents of European stock have a greater amount of the Neanderthal genome than those of Asia or Africa....

(24,146 posts)they have all manner of wonderful science and nature documentaries and plenty of shows to keep me busy. not going to be your best bet if you want more current tv, though

(2,252 posts)Slightly off topic, but since the humorously intended comments about Bonobos were posted - Bonobos Join Chimps as Closest Human Relatives
More at the link. The original publication in Nature is here. You can also download a copy of the supplementary information for the research.
PS: Be careful when spellchecking posts that discuss bonobos - the checker wants to substitute bonbons.
