Correct me if I'm wrong, doesn't the Ubook indicate that humans descended from the lemur side? This article may not mirror Ubook science exactly, however, I found this interesting.

(CNN) -- Scientists hailed Tuesday a 47-million-year-old fossil of an ancient "small cat"-sized primate as a possible common ancestor of monkeys, primates and humans.
Scientists say the fossil, dubbed "Ida," is a transitional species, living around the time the primate lineage split into two groups: A line that would eventually produce humans, primates and monkeys, and another that would give rise to lemurs and other primates.

The fossil was formally named Darwinius masillae, in honor of the anniversary of Charles Darwin's 200th birthday.

"This is the most complete primate fossil before human burial," said Dr. Jorn Hurum, of the Natural History Museum at the University of Oslo, who led the study of the fossil, a young female primate.

"And it's not a few million years old; it's 47 million years old," Hurum said, speaking at a news conference at the American Museum of Natural History in New York.

The fossil was discovered in 1983 in the Messel Pit, Germany, near Frankfurt, and had been until recently in private collections, according to an article published Tuesday in the scientific journal PLoS ONE, a publication of the Public Library of Science.
However, because it was split into two parts, its significance was not immediately recognized.
An international team of scientists, which Hurum led, conducted a detailed forensic analysis of the fossil for the past two years, the release said.

Hurum nicknamed the fossil Ida after his young daughter, he said.

The fossil's body is nearly complete; only part of one leg is missing, according to Hurum. In addition to the bones, the softer features are also preserved, as are the remnants of its last meal: fruits, seeds and leaves, which were found in Ida's gut, according to the scientists.

"It's such a beautiful specimen," Hurum said of Ida. He said the fossil is about 2 feet long, "like a small cat in size."

The fossil has both adult and baby teeth, indicating that it was weaned and about 9 months old when it died, the PLoS article said.

She would have eventually grown to the size of a lemur, the article said.

The young primate fossil does not have two crucial anatomical features found in lemurs: a grooming claw on the second digit of its foot and a fused row of teeth in the middle of its lower jaw, known as a toothcomb, the scientists said.

X-rays revealed a broken wrist, which the team of scientists believe may have contributed to Ida's death, according to a news release from the museum at Oslo.

Ida may have been overcome by carbon dioxide gas while drinking from the Messel lake, which was often covered by a low-lying blanket of the gas, the news release said. Hampered by the broken wrist, the young primate may have fallen into unconsciousness and may have slipped into the lake. The primate sunk to the bottom and was preserved for 47 million years, the news release said.

Hi Daniel. God's Peace be with you.

It's an amazing discovery. I posted this on DebatingChritianity.com

Zzy, As a reader of The Urantia Book I come across new scientific discoveries that have been anticipated by TUB many years in advance.

Like this article in yesterday's Wall Street Journal someone shared on a UB site:
The Wall Street Journal
May 15, 2009
Fossil Discovery Is Heralded
HERE

Here is some breaking news about a find related to the common ancestor of humans, monkeys, and apes. From WSJ May 15, 2009:

By GAUTAM NAIK

In what could prove to be a landmark discovery, a leading paleontologist said scientists have dug up the 47 million-year-old fossil of an ancient primate whose features suggest it could be the common ancestor of all later monkeys, apes and humans.

Anthropologists have long believed that humans evolved from ancient ape-like ancestors. Some 50 million years ago, two ape-like groups walked the Earth. One is known as the tarsidae, a precursor of the tarsier, a tiny, large-eyed creature that lives in Asia. Another group is known as the adapidae, a precursor of today's lemurs in Madagascar.

Based on previously limited fossil evidence, one big debate had been whether the tarsidae or adapidae group gave rise to monkeys, apes and humans. The latest discovery bolsters the less common position that our ancient ape-like ancestor was an adapid, the believed precursor of lemurs.[lemur] AP Photo/Karen Tam

A fossil discovery suggests humans may be descended from an animal that resembles present-day lemurs like this one.

Philip Gingerich, president-elect of the Paleontological Society in the U.S., has co-written a paper that will detail next week the latest fossil discovery in Public Library of Science, a peer-reviewed, online journal.

"This discovery brings a forgotten group into focus as a possible ancestor of higher primates," Mr. Gingerich, a professor of paleontology at the University of Michigan, said in an interview.

The discovery has little bearing on a separate paleontological debate centering on the identity of a common ancestor of chimps and humans, which could have lived about six million years ago and still hasn't been found. That gap in the evolution story is colloquially referred to as the "missing link" controversy. In reality, though, all gaps in the fossil record are technically "missing links" until filled in, and many scientists say the term is meaningless.

Nonetheless, the latest fossil find is likely to ignite further the debate between evolutionists who draw conclusions based on a limited fossil record, and creationists who don't believe that humans, monkeys and apes evolved from a common ancestor.

Scientists won't necessarily agree about the details either. "Lemur advocates will be delighted, but tarsier advocates will be underwhelmed" by the new evidence, says Tim White, a paleontologist at the University of California, Berkeley. "The debate will persist."

The skeleton will be unveiled at New York City's American Museum of Natural History next Tuesday by Mayor Michael Bloomberg and an international team involved in the discovery.

According to Prof. Gingerich, the fossilized remains are of a young female adapid. The skeleton was unearthed by collectors about two years ago and has been kept tightly under wraps since then, in an unusual feat of scientific secrecy.

Prof. Gingerich said he had twice examined the adapid skeleton, which was "a complete, spectacular fossil." The completeness of the preserved skeleton is crucial, because most previously found fossils of ancient primates were small finds, such as teeth and jawbones.

It was found in the Messel Shale Pit, a disused quarry near Frankfurt, Germany. The pit has long been a World Heritage Site and is the source of a number of well-preserved fossils from the middle Eocene epoch, some 50 million years ago.

Prof. Gingerich said several scientists, including Jorn Hurum of Norway's National History Museum, had inspected the fossil with computer tomography scanning, a sophisticated X-ray technique that can provide detailed, cross-sectional views. Dr. Hurum declined to comment.

Although the creature looks like a lemur, there are some distinctive physical differences. Lemurs have a tooth comb (a tooth modified to help groom fur); a grooming claw; and a wet nose. Dr. Gingerich said that the adapid skeleton has neither a grooming claw nor a tooth comb. "We can't say whether it had a wet nose or not," he noted.

Since the fossilized creature found in Germany didn't have features like a tooth comb or grooming claw, it could be argued that it gave rise to monkeys, apes and humans, which don't have these features either.

The Urantia Book said in 1946:

P.700 - 2 The great event of this glacial period was the evolution of primitive man. Slightly to the west of India, on land now under water and among the offspring of Asiatic migrants of the older North American lemur types, the dawn mammals suddenly appeared. These small animals walked mostly on their hind legs, and they possessed large brains in proportion to their size and in comparison with the brains of other animals. In the seventieth generation of this order of life a new and higher group of animals suddenly differentiated. These new mid-mammals--almost twice the size and height of their ancestors and possessing proportionately increased brain power--had only well established themselves when the Primates, the third vital mutation, suddenly appeared. (At this same time, a retrograde development within the mid-mammal stock gave origin to the simian ancestry; and from that day to this the human branch has gone forward by progressive evolution, while the simian tribes have remained stationary or have actually retrogressed.)

P.703 - 1 About one million years ago the immediate ancestors of mankind made their appearance by three successive and sudden mutations stemming from early stock of the lemur type of placental mammal. The dominant factors of these early lemurs were derived from the western or later American group of the evolving life plasm. But before establishing the direct line of human ancestry, this strain was reinforced by contributions from the central life implantation evolved in Africa. The eastern life group contributed little or nothing to the actual production of the human species.

1. THE EARLY LEMUR TYPES - P.703

P.703 - 2 The early lemurs concerned in the ancestry of the human species were not directly related to the pre-existent tribes of gibbons and apes then living in Eurasia and northern Africa, whose progeny have survived to the present time. Neither were they the offspring of the modern type of lemur, though springing from an ancestor common to both but long since extinct.

P.703 - 4 With the passing of time the seacoast of India southwest of the mountains gradually submerged, completely isolating the life of this region. There was no avenue of approach to, or escape from, this Mesopotamian or Persian peninsula except to the north, and that was repeatedly cut off by the southern invasions of the glaciers. And it was in this then almost paradisiacal area, and from the superior descendants of this lemur type of mammal, that there sprang two great groups, the simian tribes of modern times and the present-day human species.

P.703 - 5 A little more than one million years ago the Mesopotamian dawn mammals, the direct descendants of the North American lemur type of placental mammal,

P.704 - 5 These aggressive little animals multiplied and spread over the Mesopotamian peninsula for more than one thousand years, constantly improving in physical type and general intelligence. And it was just seventy generations after this new tribe had taken origin from the highest type of lemur ancestor that the next epoch-making development occurred--the sudden differentiation of the ancestors of the next vital step in the evolution of human beings on Urantia.

Although it's not conclusive, IT'S A HUGE DISCOVERY Zzy! reviewing the little information I have. I would say "adapid" may have led to humans and the "tarsidae" group may have led to "the simian tribes of modern times."

Time will tell Z. Time will tell. :-) have good day Z. ;)

I'm going to add a link to this discovery to the Science Page whose Link I posted for Once and encouraged you to review.

Peace you guys. You see God isn't against evolution. God was waiting for us to advance enough to understand it. Now God's giving us insight to and encouragement for continuing our scientific discovery of God's processes like evolution and creation.
The more we discover how much we are Loved by God, the more we want to do God's Will.

What is the current status of this fossil? Does the scientific community accept it as an ancestor of humans?

Is there more recent evidence that humans originated in Asia instead of Africa?

Slowly but certainly the geneticists appear to be closing in on that fact, Howard. Came across this article recently that specifically mentions 37,000 years ago, but doesn't directly refute the "out of Africa" error.

By Charles Choi, LiveScience Contributor

Neanderthals apparently last interbred with the ancestors of today's Europeans after modern humans with advanced stone tools expanded out of Africa, researchers say.

The last sex between Neanderthals and modern humans likely occurred as recently as 47,000 years ago, the researchers added.

Modern humans once shared the globe with now-departed human lineages, including the Neanderthals, our closest known extinct relatives. Neanderthals had been around for about 30,000 years when modern humans appeared in the fossil record about 200,000 years ago. Neanderthals disappeared about 30,000 year ago.

In 2010, scientists completed the first sequence of the Neanderthal genomeusing DNA extracted from fossils, and an examination of the genetic material suggested that modern humans' ancestors occasionally successfully interbredwith Neanderthals. Recent estimates reveal that Neanderthal DNA makes up 1 percent to 4 percent of modern Eurasian genomes, perhaps endowing some peoplewith the robust immune systems they enjoy today.

The Neanderthal genome revealed that people outside Africa share more genetic variants with Neanderthals than Africans do. One possible explanation is that modern humans mixed with Neanderthals after the modern lineage began appearing outside Africaat least 100,000 years ago. Another, more complex scenario is that an African group ancestral to both Neanderthals and certain modern human populations genetically diverged from other Africans beginning about 230,000 years ago. This group then stayed genetically distinct until it eventually left Africa.

]To shed light on why Neanderthals appear most closely related to people outside Africa, researchers looked at similar DNA chunks in European and Neanderthal genomes. When sperm and egg cells are created, the strands of DNA within them break and rejoin to form new combinations of genetic material. This "recombination" decreases the length of the chunks in each generation. By comparing lengths, "we can estimate when the two populations last shared genes," explained researcher Sriram Sankararaman, a statistical geneticist at Harvard Medical School.

]The research team estimates modern humans and Neanderthals last exchanged genes between 37,000 and 86,000 years ago, and most likely 47,000 to 65,000 years ago. This is well after modern humans began expanding outside Africa, but potentially before they started spreading across Eurasia.

These findings suggest modern humans last shared ancestors with Neanderthals during the period known as the Upper Paleolithic. Back then, modern humans had begun using relatively advanced stone tools[/color], such as knife blades, spear points, and engraving and drilling implements.

"I think we will be able to get new insights on how modern humans adapted as they occupied new regions," Sankararaman told LiveScience. "It shows the power of genetic data to learn about historical events."[/color]

Future research will explore other prehistoric interbreeding events, such as the apparent mixing between ancestors of modern Papuans and the recently unearthed extinct human lineage known as Denisovans.

"There are technical challenges here," Sankararaman said. "Papuans have had gene flow from Neanderthals and from Denisovans. That makes it challenging to tease their contributions apart."

The scientists detailed their findings online Oct. 4 in the journal PLoS Genetics.

What about the multiregional hypothesis? The Urantia Book says that, while Andon and Fonta were born in Asia, there were other strains from which the first humans could have originated. Perhaps some humans originated in Asia while others in Africa.
