Fossils shed new light on the human-gorilla split
#Cosmoread: What could be relatives of gorillas primitive fossil species suggests that humans and gorillas later than what has been suggested in recent years split 10 million years ago, millions, researchers say. Conclusion continent where the monkey and human species first developed could help in resolving a dispute, the scientists added.
However, the fossil record of human evolution is still patchy, it is better to great apes such as chimpanzees and gorillas than is understood. Since some great ape fossil found in Africa so far, “forcing some scientists have suggested that the African apes and humans must have evolved in Eurasia ancestors,” said study senior author Gen Suwa, a paleoanthropologist at the University of Tokyo said.
Monkey and human species development highlights, Suwa and colleagues examined Ethiopia’s Afar Rift. Previous research explored the Afar rift of some of the earliest known fossil hominins – that is, human and related species, dating back to the ape species split.
The research team from the Afar rift, Chorora focus on the formation of the oldest known sediments. (Formation Chorora, gets its name from a village in the area.)
In 2007, Suwa and colleagues formed Chorora that belonged to an extinct monkey they named Chororapithecus abyssinicus discovered nine gorilla-sized teeth. “Chororapithecus” “Chorora monkey,” it means the “abyssinicus” Abyssinia, Ethiopia’s former name is mentioned.
Chororapithecus stem and leaves teeth appeared for dinner special, and modern gorillas, which suggests that those resembled “Chororapithecus gorilla lineage probably represents an ancestral branch,” Suwa told Live Science. As such, heand Chororapithecus his colleagues to pin down how old was in order better to indicate, human and gorilla species can be when first wanted to vary.
Chorora volcanic rocks and up and down the formation of sediment once the magnetic particles by analyzing fossils, researchers have new evidence that Chororapithecus was probably about 8 million years.
See the age and location of these fossils and modern human monkey strong lines and originated in Africa, Asia, the researchers said.
“So far, in the south of the Sahara is a mammalian fossils safe 8000000-9000000 dated years ago,” Suwa said. “Any and all African fossils from the critical period will help unravel the story of human origins and evolution. These are the first such fossils.”
Also, until recently, “Most scientists, especially genetics, human-chimp split 5 million years thought as recently as the first had been, and that human-gorilla split only about 7000000-8000000 years ago, “Suwa said. “It contradicted the fossil record, for example, on the human side of the division began to Sahelanthropus fossil Ardipithecus kadabba such as Chad and Ethiopia and were 6 million years old . Or perhaps, in the case of Chad fossil, 7 million years old. ”
The new findings suggest that Chororapithecus 8 million years old, so the “real gorilla human splits up to several hundred thousand years ago, must have been,” Suwa said. Therefore, the study shows that the human-gorilla split may have occurred “nearly 10 million years ago and the human-chimp split about 8 million years ago,” he said.
