December 9, Beijing time, the United States, "Time" magazine selected the top ten scientific discoveries in 2009 on Tuesday, of which the oldest human ancestor "Eddie" found the top spot, the moon found water, large Hadron collider restart On the list.
1. The oldest human ancestor "Eddie"
"Eddie" is the oldest human skeleton fossil ever discovered before. Her fingers are very long, 4 feet tall (about 1.21 meters), and her head is not as big as a bonobo. Faced with such a woman, it is difficult for us to have a love. After splicing more than 100 fragments of fossils to be discovered in Ethiopia, the scientists obtained skeleton specimens of this woman's Aldıra Mita (Eddie). Eddie lived 4.4 million years ago until 1992, when her bone fragments were first discovered.
After 17 years of research, a team of scientists led by Tim White of the University of California, Berkeley, published a series of articles in the journal Science in October to publish a comprehensive analysis report on Eddie. According to their research, Eddy is not similar to a chimpanzee despite being initially considered the descendant of a common ancestor of humans and chimpanzees. In addition, although living in the forest area, Eddy has the ability to walk on two feet. This discovery weakened the importance of open grassland for human evolution into bipedal walking.
