Return of the Neanderthals

Virginia Hughes
for National Geographic News
Published March 6, 2013

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 species—the Pyrenean ibex, a wild mountain goat also called a bucardo—though 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.

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.

That might have caused some embarrassing morning revelations, so to speak.

Or worse:

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.

Talk about embarrassing mornings revelations.

Just kidding, of course.

All the world's lifeforms are cousins.

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!

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....

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

It's a very exciting time to be alive in many respects. Our knowledge doubles and redoubles so quickly now.

11. Bonobos Join Chimps as Closest Human Relatives...

Slightly off topic, but since the humorously intended comments about Bonobos were posted - Bonobos Join Chimps as Closest Human Relatives

Chimpanzees now have to share the distinction of being our closest living relative in the animal kingdom. An international team of researchers has sequenced the genome of the bonobo for the first time, confirming that it shares the same percentage of its DNA with us as chimps do. The team also found some small but tantalizing differences in the genomes of the three species—differences that may explain how bonobos and chimpanzees don't look or act like us even though we share about 99% of our DNA.


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.
