New Fossils Uncover the Face of Human and Monkey Ancestors

New Fossils Uncover the Face of Human and Monkey Ancestors
From all the species on earth, the most expensive human apes, including small apes like ungca and great apes such as gorillas and orangutans. According to the researchers, this whole group of hominoids branched into humans, ungca, gorillas, and other monkeys some 23-5 million years ago in the Miocene epoch.

If so, surely humans and apes have the same ancestors. The likeness of this ancestor was also a big question for the researchers.

Now, one possibility emerges from a 13-million-year-old skull. According to a recent study published in the journal Nature, the skull comes from the primate way of tree climbers and fruit-eaters that hold the ancestors of humans and apes.

It still has the roots of milk teeth and no adult teeth are grown and based on a three-dimensional X-ray scan, the researchers believe this primate baby is still about 16 months in.

They are not sure the exact cause of his death, but love the ashes that cover the fossils of the dead babies as a result of volcanic eruptions.

"Based on his teeth, we can also find out that it is a fruit eater," said one study author, Eron Miller, who is also a primate and paleoanthropologist at Wake Forest University to Live Science August 10, 2017.

Referring to the shape of the teeth, primates derived from the genus Nyanzapithecus are still associated with hominoids. However, this fossil tooth is larger than the other members of Nyanzapithecus so that the researchers also decision is a new species.

They also escaped the name of Nyanzapithecus alesi in honor of the fossil hunter John Ekusi who discovered in 2014 at Lake Turkana, northern Kenya. Ekusi saves the nickname "Alesi" because "ales" has the meaning of "ancestor" in Turkana.

Lead author of the study, Isaiah Nengo of Stony Brook University, New York, said in a press release, N alesi is a member of a primate group that has existed in Africa since 10 million years ago. Alesi's discovery shows this group is close to the origin of apes and humans living today, and this origin is Africa.

Unfortunately, the researchers could not fit Alesi women or men because the primates were too young to show any significant difference. However, the size of the skull and teeth showed that adult N alloys weighed about 11.3 kilograms.

Then, a small snout part will make Alesi look like a baby ungka. The difference, the inside of Alesi's ear indicates that Alesi can not do acrobatics swinging in the trees like ungka.

"(Alesi) probably has a slower climbing form of locomosi like chimps," Miller said.

Christopher Gilbert, one of the authors and paleoanthropologists from Hunter College, Alesi, said that since N is closely related to the ancestors of all monkeys, this specimen can show the likeness of all modern apes and humans.

"Moreover, our specimens are most similar to ungca compared to other living apes, therefore, (N alesi) may support the idea of ​​the ancestors of humans and gay ungka," he said.
