. The recent sequencing of the gorilla, chimpanzee and bonobo genomes confirms that supposition and provides a clearer view of how we are connected: chimps and bonobos in particular take pride of place as our nearest living relatives, sharing approximately 99 percent of our DNA, with gorillas trailing at 98 percent.

populations are being compared.

We share 98% to 99% of our DNA with chimps, but the other studies of modern humans and Neanderthals are making comparisons within the human line, from the 1% of DNA that we don't share with chimps. Of that 1%, only 7% of our DNA is uniquely modern.

For example, only a small percent of modern humans have blue eyes compared with other modern humans around the world. (Don't know the actual figure.) But all modern humans, regardless of eye color, share 98% to 99% chimp DNA.

I should brush up on my reading comprehension. And that seems like a really small percentage, much less than I would have guessed. Very interesting.

Yes, it is a small percent. I guess it reflects how young modern humans are on the hominid family tree. We've only been around for about 130,000 years to evolve traits that are unique to us. The most recent ancestors to modern humans had hundreds of thousands of years to evolve their traits, and before them, it goes into millions of years.
