The Houston Museum made arrangements for exhibiting at ten other museums, including the Pacific Science Center in Seattle. The skeleton presents a small skull akin to that of non-hominin apes, plus evidence of a walking-gait that was bipedal and upright, akin to that of humans (and other hominins); this combination supports the view of human evolution that bipedalism preceded increase in brain size. [22], One of the most striking characteristics of the Lucy skeleton is a valgus knee,[23] which indicates that she normally moved by walking upright. [3][16], In the afternoon, all members of the expedition returned to the gully to section off the site and prepare it for careful excavation and collection, which eventually took three weeks. Johanson recovered Lucy's left innominate bone and sacrum. That first evening they celebrated at the camp; at some stage during the evening they named fossil AL 288-1 "Lucy", after the Beatles' song "Lucy in the Sky with Diamonds", which was being played loudly and repeatedly on a tape recorder in the camp. Beginning in 2007, the fossil assembly and associated artifacts were exhibited publicly in an extended six-year tour of the United States; the exhibition was called Lucy's Legacy: The Hidden Treasures of Ethiopia. These were: Donald Johanson, an American paleoanthropologist and curator at the Cleveland Museum of Natural History, who later founded the Institute of Human Origins, now part of Arizona State University; Mary Leakey, the noted British paleoanthropologist; and Yves Coppens, a French paleoanthropologist now based at the Collège de France which is considered to be France's most prestigious research establishment. The cranial capacity was about 375 to 500 cc. Follow us,&. The creature had a small brain like a chimpanzee, but the pelvis and leg bones were almost identical in function to those of modern humans, showing with certainty that Lucy's species were hominins that had stood upright and had walked erect.

Lucy also had a lordose curve, or lumbar curve, another indicator of habitual bipedalism. Two scientists had taken a Land Rover out that day to map in another locality.

[17], Over the next three weeks the team found several hundred pieces or fragments of bone with no duplication, confirming their original speculation that the pieces were from a single individual; ultimately, it was determined that an amazing 40 percent of a hominin skeleton was recovered at the site.
There are indications of degenerative disease to her vertebrae that do not necessarily indicate old age.

These people then migrated southward into North America sometime after 17,000 years ago. First they must climb down a 30-foot (9 m) ladder in a nearby sinkhole. People have far more copies of mitochondrial DNA than chromosomal DNA, making it easier for researchers to study. The floor disappeared under us, and we could not see across to the other side.

"It is like a miniature version of the La Brea Tar Pits, only without the tar and with better preservation," Chatters said. The ancient skeleton of a teenage girl found in an underwater cave in Mexico may be the missing link that solves the long-standing mystery behind the identity of the first Americans, researchers say. At first view nothing was immediately visible, but as they turned to leave a fossil caught Johanson's eye; an arm bone fragment was lying on the slope.
They focused on genetic material from her mitochondria — the powerhouses of the cell, which possess their own DNA and get inherited from the mother. Some nine years later, and now assembled altogether, she was returned to Ethiopia. "The people themselves were few; they were highly nomadic and seem to have buried or cremated the dead where they fell, making the locations of graves unpredictable; also, geologic processes have destroyed or deeply buried their graves.".
Each partial skeleton is more complete than the famous “Lucy,” an early hominin species found in 1974 in Ethiopia. This genetic signature is found only in the Americas, probably first developing in Beringia after populations there split from Asians. The skeletons are now under the custodianship of the University of Witwatersrand. [1][2][3], The Lucy specimen is an early australopithecine and is dated to about 3.2 million years ago. "We had no idea what we might find when we initially entered the cave, which is the allure of cave diving," said study author Alberto Nava of Bay Area Underwater Explorers in Berkeley, California. Lucy: This may be the most famous "missing link." The Lucy skeleton finding was momentous to an earlier generation. [8][35], The fossil's discoverer Don Johanson stated his concern for the possibility of damage, but did not oppose touring and exhibiting Lucy, as he felt it would raise awareness of human-origins studies. During evolution of the human lineage these muscles seem to have weakened with the loss of the myosin gene MYH16, a two base-pair deletion that occurred about 2.4 million years ago. Lucy is the common name of AL 288-1, several hundred pieces of fossilized bone representing 40 percent of the skeleton of a female of the hominin species Australopithecus afarensis. Though the sacrum was remarkably well preserved, the innominate was distorted, leading to two different reconstructions. The researchers now hope to sequence Naia's entire genome. Shortly thereafter, he saw an occipital (skull) bone, then a femur, some ribs, a pelvis, and the lower jaw. Lucy was exhibited at the Discovery Times Square Exposition in New York City from June until October 2009. Lucy the pre-human hominid and fossil hominin, captured much public notice; she became almost a household name at the time. "Lucy" is the name given to a skeleton found in Ethiopia in 1974.
The site lay about 2.5 kilometres (1.6 mi) from the site where "Lucy" subsequently was found, in a rock stratum 200 feet (61 m) deeper than that in which the Lucy fragments were found. Read another story from us: Lucy’s baby, the world oldest known child found in Ethiopia is 120,000 years older than Lucy. A later reconstruction by Tim White showed a broad iliac flare and a definite anterior wrap, indicating that Lucy had an unusually broad inner acetabular distance and unusually long superior pubic rami.
[9], In November 1971, near the end of the first field season, Johanson noticed a fossil of the upper end of a shinbone, which had been sliced slightly at the front. All in all, the earliest Americans more closely resemble modern peoples of Africa, Australia and the Southern Pacific Rim.
This operation was complicated by how divers who visited Hoyo Negro without authorization had almost knocked Naia's skull into a deep chasm. At the same time, Australopithecus sediba’s hands have grasping capabilities, which suggests that the species may also have used tools. Excavation, preservation, and analysis of the specimen Ardi was very difficult and time-consuming; work was begun in 1992, with the results not fully published until October 2009.
[26] Rak et al.
[12][13][14][15][1][2], By Johanson's later (published) accounts, both he and Tom Gray spent two hours on the increasingly hot and arid plain, surveying the dusty terrain. The differences seen in the face and head between the earliest Americans and modern Native Americans are probably due to evolutionary changes that happened during or after the colonization of the Americas. As glaciers worldwide started melting about 10,000 years ago, the cave filled with water — sea levels were as much as 360 feet (120 m) lower then.
", Naia's skull had the face and head features one would expect of the earliest Americans. "Only technical cave divers can reach the bottom. "We were lucky to find a tooth that did not have an opening in the crown, so DNA still happened to be inside," Chatters added. (Located in Los Angeles, the La Brea Tar Pits hold the world's richest deposits of ice age fossils.). ", "We pointed our lights down and to the sides — all we could see was darkness," Nava recalled.
The Lucy skeleton is preserved at the National Museum of Ethiopia in Addis Ababa. "Current technology permits this, but it will still be challenging," said study author Brian Kemp, a molecular anthropologist at Washington State University in Pullman. Near it lay a fragment from the back of a small skull.
[24] She apparently had physiological flat feet, not to be confused with pes planus or any pathology, even though other afarensis individuals appear to have had arched feet.[25]. The term originated to describe the hypothetical intermediate form in the evolutionary series of anthropoid ancestors to anatomically modern humans.
The researchers also hope to find more skeletons that support their findings. The cranium of Malapa hominid 1 (MH1) from South Africa, named “Karabo”. "We felt as if our powerful underwater lights were being destroyed by this void, so we called it 'Black Hole' (a cosmic object that absorbs all light), which in Spanish is Hoyo Negro."
It turned out, she's as solid as a rock. The length ratio of her humerus (arm) to femur (thigh) is 84.6%, which compares to 71.8% for modern humans, and 97.8% for common chimpanzees, indicating that either the arms of A. afarensis were beginning to shorten, the legs were beginning to lengthen, or both were occurring simultaneously. [17], Lucy was 1.1 m (3 ft 7 in) tall,[18] weighed 29 kg (64 lb), and (after reconstruction) looked somewhat like a chimpanzee.
