Some Pacific Islanders Have DNA Not Linked To Any Known Human Ancestor

http://all-that-is-interesting.com/pacific-islanders-ancestor?utm_campaign=pdsoban&utm_source=facebook&utm_medium=social

Most everyone knows that the islands of the South Pacific are some of the most remote and unique places on Earth, but a new study reveals just how unique they really are.

According to a report from the University of Texas MD Anderson Cancer Center in Houston, researchers have found traces of a previously unknown extinct hominid species in the DNA of the Melanesians, a group living in an area northeast of Australia that encompasses Papua New Guinea and the surrounding islands.

A computer analysis suggests that the unidentified ancestral hominid species found in Melanesian DNA is unlikely to be either Neanderthal or Denisovan, the two known predecessors of humankind to this point.

Archaeologists have found many Neanderthal fossils in Europe and Asia, and although the only Denisovan DNA comes from a finger bone and a couple of teeth discovered in a Siberian cave, both species are well represented in the fossil record.

But now genetic modeling of the Melanesians has revealed a third, different human ancestor that may be an extinct, distinct cousin of the Neanderthals.

It looks like I should watch the documentary on the Human Genome Project again, even though it doesn't have this new information.

We did ours through National Geographic too. Seems to be mostly Celtic. Very early into Europe. My ancestors may have killed off those last Neanderthals.

Not that they won't try...it's their modus operandi with information that contradicts their world view. Can you imagine what this world might be like if they didn't destroy the Library of Alexandria or destroy all the books of the Mayans. Utter shame.

10. There's a great free course you can audit online...

Human Origins is the name of the class, taught by the leader of the team that discovered Lucy.

If you want the credit for the class with Arizona State you have to pay a proctoring fee then pay the credit hours if you pass, but it's open to anyone to audit if they just want to know more.

Many, many different hominids exited Africa before homo sapiens. Whether interbreeding was likely to have been attempted or been successful is unknown, but is definitely a possibility.

Especially if they retained the same number of chromosomes. Horses, donkeys, and zebras all evolved from a common ancestor 4.5 million years ago, but the reason mules are infertile is that during that time either donkeys lost or horses gained an extra pair of chromosomes. But they will still attempt to breed because mating signals aren't all that different.

I don't have time to do it now, so I was hoping to go through it later. But it starts on Jan 8, 2018. Plenty of time for me to make time for that course.

And it's in English!! Who knew Americans could speak English??

(Just kidding, my American friends - I'm Australian and, for sure, we don't speak English).

Thanks for the info, Moriah. That looks like a great course. I've already signed up.

16. The word "sheila" is pretty much discouraged these days.

It's viewed as pretty negative.

We Aussies have had (and still have) a few attitudes towards women and our indigenous people that we can't be proud of.

Just give us a fair suck of the saveloy. We're better than we used to be.

Cheers, mate. Good onya.

Voyage to sunken continent of Zealandia reveals thousands of fossil specimens

Scientists now believe 5,000,000 sq km mass served as a land bridge millions of years ago

Jon Sharman
Thursday 5 October 2017 12:15 BST

Scientists have uncovered more than 8,000 fossils during an expedition to a lost, underwater continent in the Pacific Ocean.

Drilling into the crust of Zealandia, thousands of feet below the surface, researchers discovered the remains of hundreds of species including pollen from land plants.

The land mass, on which New Zealand sits, was announced as the globe's newest continent earlier this year. It spans 5,000,000 sq km and is a distinct geological entity, a landmark study declared in the summer.

Now it is believed Zealandia was once much closer to the ocean's surface and may have served as a land bridge for animals moving around the south Pacific region.

22. Do they get to name the hominid ancestor if they don't have bones?

In fact, they only have circumstantial evidence that it must have existed. This is kind of like homo floresiensis, the 'hobbit people' in Indonesia.

Had several different Sumerian myths, including how she met the husband that doesn't mourn her in the later Descent story.

Part of the required reading in my trad, even if I'm more drawn to the Mabinogion.

The Mabinogion is a collection of Celtic mythology, including the story of Rhiannon, etc.

I don't know who did the translation I had of it, but I had been lucky enough to find a hardback version.
