The greatest mass extinction in the 3

The greatest mass extinction in the 3.5-billion-year history of life on Earth probably occurred as a result of climate change resulting from a series of huge volcanic eruptions, researchers believe. The age of the remains was determined by dating nearby volcanic material.The hominid is also marked out by its humanlike diamond-shaped upper canine teeth in contrast to the v-shaped upper canines of chimpanzees. However, scientists concede that the creature resembled a chimpanzee more than a human.Nevertheless, Professor Tim White of the University of California pointed out that A.ramidus was an important ancestor to later species of hominids. “It is becoming clear that we’re seeing the basic grade from which Australopithecus evolved,” he said.

The most famous Australopithecus fossils are those belonging to “Lucy”, a female skeleton discovered in Ethiopia in the 1970s.A.ramidus could represent an early step on the path of humanity, as well as indicating the origins of a number of other extinct hominid species.While it is unclear what habitat the hominids would have lived in, fossils found in the vicinity of the site reveal that A.ramidus lived alongside mole-rats, monkeys and cow-like grazing animals. The so-called “australopithecines” are widely believed to have human lineage. All the finds belong to the Ardipithecus ramidus species, which was discovered a decade ago.Sileshi Semaw, of the Craft Stone Age Institute, described the find as “very important” because it confirmed that hominids walked upright on two feet up to 4.5 million years ago. Scientists say that the features of a foot bone uncovered at As Duma, in the north of the country, prove that the hominid it belonged to walked upright like present-day humans. Fossil hunters in Ethiopia have discovered the remains of at least nine primitive hominids, nearly 4.5 million years old, which scientists claim could help fill some of the gaps in early human evolution

The finds, revealed in Nature magazine, mainly consist of teeth and jaw fragments, but also include parts of feet and hands.

In many consumer electronics markets, Sony retains little advantage but doggedly remains in them. Analysts believe it ought to concentrate on areas where it has an advantage. One obvious area is games machines, a sector where Sony has had phenomenal success.Its PlayStation was launched in 1994.
