Archicebus achilles | Chinese Academy of Sciences
An analysis of the fossil discovery about 10 years ago in Hubei Province, China which is the fossil of an ancient primate. It turns out from the results of the latest analysis proves that the ancient fossils belonged to the earliest primates, is the oldest ancestor of humans.
Fossil primates from Hubei China has aged about 7 million years older than the previous oldest fossil primate species Darwinius fossil of which was found in the region massilae Messel - Germany.
Fossil primates from China's Hubei given where Archicebus achilles. Allegedly the primate species that is very active. Fauna weighs no more than 30 grams with a body length of about 55 cm; has a great eye and thought the food was insects.
According to the identification of a lead Xijun Ni fossil analysis of the Chinese Academy of Sciences says that Archicebus achilles has a long tail, slender legs, a round face and legs that have the ability to grasp. Xijun also estimated Archicebus Achilles also has a distinctive hue.
The process of identification of fossil Archicebus achilles using the facilities of Eropean Sunchrotron Radiation Facility is located in Grenoble - France. Through these facilities can produce 3D images from fossil Archicebus achilles. The identification process is done with the image of the model.
The identification of primates showed that the characters were the achilles Archicebus as a combined character two types / classes of different primates. The incorporation of primates like tarsiers and anthropoida primate groups. Anthropoida primate group encompasses primates chimpanzees, bonobos and humans. Anthropoida primate natural evolution process has been separated from the class of primates like tarsiers in millions of years ago. Characters contained in primates anthropoida Archicebus achilles heel is on his feet.
Estimated Archicebus achilles live at 55 million years ago in China region; Archicebus hyperactive achilles including primates. On the life of Achilles Archicebus future global warming is called as the Palaeocene-Eocene Thermal Maximum. That is the time when the world is only found tropical and subtropical regions where the palm trees are found in the region paleman to Alaska.
With the characteristics of primates Archicebus achilles can be regarded as the oldest human ancestor. Not a direct human ancestor but it is the beginning of the process towards the creation of human evolution.
Christopher Soligo, biological anthropologist from University College London said the findings are very valuable because it will help scientists uncover the evolutionary process in primates.
Chris Bear of the Carnegie Museum of Natural History in Pittsburgh revealed that these fossils indicate that the most important stage in the evolution of primates, including anthropoida group, took place in Asia, and in Africa as previously thought. Bear also said that there are two supporters of Genetic Data is data and data is the fossil record.
Genetic data suggest that mammalian and primate DNA sequences that exist at this time indicates that the closest to primates and lemurs are tree rats. Lemurs are tree rats and animals that live in Asia today is in Southeast Asia.
Based on the fossil record shows that the achilles Archicebus fossil primate lived about 55 million years ago were discovered in Africa. But the findings are limited because of the new fossils discovered fossils of teeth and some bones.
According to Beard that Africa is the continent with the current mammal species endemic to reflect modern mammals that live in Australia today. This is according to Beard weird because as we have seen in other continents.
A scenario estimates that primates evolved in Asia then descent from Achilles Archicebus subsequently traveled to Africa. Continent that occurred subsequent to the evolutionary process of human creation. According Berd also added that the trip to Africa anthropoida primate species occurred about 38 million years ago has been known by scientists. But to this day scientists still do not know how the trip was done.
At that time the African region is still not connected to southwest Asia. Estimated anthropoida across primate species towards the African waters. It is not easy but the possibility it could happen. The fossil analysis published in the journal Nature, published on Wednesday (05/06/2013).
