Department of human grandmother Lucy from the tree fall dead, that ancient humans had tree dwelling iptd-651

Department of human grandmother Lucy from the tree fall dead, a study proving that ancient humans had the tree habitat recently published that "human grandmother", the world’s most famous ancient human – Lucy (Lucy), is from the high tree fell wounded died. So far, Lucy is one of the oldest and most complete fossil remains. In 1974, Lucy’s bones was found in the Afar region of Ethiopia in africa. She is believed to be living in the age of about 3 million 180 thousand years, is one of the important evidence of "human beings originated in Africa". The researchers published fossil copies of John Kappelman in his lab, 3D print verified the conclusion of Lucy is living in 3 million 180 thousand years ago, the remains of human ancestors, belonging to the genus Australopithecus, a (Australopithecus afarensis, referred to as Australopithecus afarensis). The researchers analyzed the fracture situation of Lucy bones, unusual found evidence that extinct Australopithecus afarensis had live in trees (arboreal habits). The paper said that Lucy may be from more than 10 meters high on the tree fell, about 60 km of shock, leading to the upper arm fracture, as well as multiple fractures of the body, and cause fatal injuries, and then died. As he fell to the ground, Lucy opened his arms to try to reduce the impact. The title of the paper is "a fatal fracture in Lucy’s fossil suggests that her death was caused by falling from a tall tree" (Perimortem in Lucy suggest mortality from fall out of tall tree). A professor of anthropology at Texas State University at Austen John · (John Kappelman); cabool door for the study of the corresponding author of the paper. The study, published online in late August 29th in the international academic journal "nature", the researchers also disclosed that the world’s most famous fossil 3D (3D) model of the electronic copy, anyone can download from the website elucy and print the 3D model, and research, in order to verify the conclusion. Map model has been released including the left knee and right shoulder and arms. Lucy fossil fossil found controversy: adhere to the fracture line fossil is caused in the process of international but also other anthropologists of John · Kabul’s conclusion objection to the door. According to the "natural" website reported, Lucy is studying the fossils of American California Chafee College (Rancho Cucamonga, Chaffey College in Rancho Cucamonga) paleoanthropologist Mark · Mel (Marc Meyer) said, chimpanzee people were injured falling from the trees, often broken spine. But Lucy doesn’t seem to have any such damage. Donald, an anthropologist at Arizona State University in the United States, Johanson is the discoverer of the Lucy fossils. Until now, Donald Johanson still insist.相关的主题文章:
