Different Species, Identical DNA

In two previous posts we introduced the speculation that Modern Humans may have interbred with Neanderthals. these articles are based on Svante Pääbo's quest to sequence the Neanderthal DNA.

In our our third installment we have some interesting revelations surfacing as the Neanderthal DNA sequencing continues.

The first revelation is both DNA's, Neanderthals and Modern Humans, are nearly identical.

Wired Magazine explains further:

"After years of anticipation, the Neanderthal genome has been sequenced. It’s not quite complete, but there’s enough for scientists to start comparing it with our own.

According to these first comparisons, humans and Neanderthals are practically identical at the protein level. Whatever our differences, they’re not in the composition of our building blocks.

However, even if the Neanderthal genome won’t show scientists what makes humans so special, there’s a consolation prize for the rest of us. Most people can likely trace some of their DNA to Neanderthals..."

For Bigfooters this is amazing, because we know Neanderthals and Modern humans were both very physically different, but according to the DNA evidence we would never know to what degree without fossil evidence.

Its a two-edge sword for Bigfoot DNA evidence. If DNA can be so similar, nearly identical, between two species, it may be hard to distinguish Bigfoot DNA.

On the other hand, we may already have Bigfoot DNA and dismissed it because it was so similar to another known species.

The second revelation is, according to studies, not all modern humans contain the same amount of Neanderthal DNA. Modern humans with African descent actually have less traceable Neanderthal DNA.

Such studies will occupy scientists for years to come. In the meantime, the researchers produced a more immediately stirring result. They compared the Neanderthal genome to genomes of five people from China, France, Papua New Guinea, southern Africa and western Africa. Among non-Africans, between one and four percent of all DNA came from Neanderthals...

...For people of African descent disappointed that they lack Neanderthal ancestry, Pääbo gave solace.

“It’s totally possible that inside Africa, there was a contribution from other archaic humans that we don’t know about,” he said. “We shouldn’t take these results as saying that only people outside Africa have caveman biology.”
