Zeresenay alemseged biography: Paleoanthropologist Zeresenay “Zeray” Alemseged

Log In. Most of these early finds consist of nothing more than a skull, a piece of jaw or some isolated teeth. In contrast to these relatively sparse finds, not only was the DRP team able to recover Selam's complete skull, but also a sandstone impression of her brain and even the hyoid bone. Due to the fragility of the hyoid, such a discovery in a species of Selam's antiquity is almost completely unprecedented.

The team was able to recover a significant portion of Selam's bones below the neck as well, including most of the spinal column, the ribs, both collar bones and both shoulder blades. These bones are almost completely absent in the fossil record, except for fragmentary pieces from Lucy.

Both knee caps and large portions of the thigh and shin bones from each leg were recovered, as well as an almost complete foot. The bones show no indications of cuts or abrasions, nor do they show the type of damage associated with scavenging carnivores; this suggests that she was buried rapidly, perhaps by a flood, shortly after her death.

It is also possible that it was this flood event which killed her. As the sediment pressed down on her through the years, Selam's bones became basically glued together in a highly compressed sandstone block. Usually paleoanthropologists struggle to reassemble fragmentary skeletal finds so as to place them back together, but Alemseged faced the exact opposite situation with Selam.

He worked painstakingly to extricate her impacted skeleton, using dental tools and removing the soil from her ribs and twisted spinal column virtually grain by grain.

The process took 6 years before it announced in and is still ongoing. Selam's skull was CT scanned and it was this method that allowed her sex and age at death to be determined. Further analyses were able to establish the size of Selam's brain which, at approximately cubic centimeters, would not have been very different from that of a 3-year-old chimpanzee.

This might point to a relatively slow brain growth in Australopithecus afarensissimilar to the brain growth pattern of modern humans, rather than that of chimps; this may point to a possible behavioral shift in Selam's species 3. The post-cranial skeleton also yielded several important lines of data regarding the locomotion movement and height of Australopithecus afarensis.

The femur thigh bonetibia shin boneand foot indicate that Selam and hence the species she represents walked fully upright, even at 3 years old, while the shoulder bones are more similar to those of gorillas.

Selam's fingers, as well as those of other members of Australopithecus afarensisare long and curved. This suggests that while the species was an effective biped while on the ground, it retained the ability to climb, which would have been a beneficial adaptation for avoiding predators, especially at night and especially for the smaller or younger members of the species.

The rare presence of the hyoid bone also yielded some significant data pertaining to Selam's species. In this bone Selam is more similar to the African great apes than she is to modern humans. His work focuses on the investigation of fundamental question of how we became humans through the process of evolution after our separation from the chimpanzees around seven million years ago.

He has published over 70 peer reviewed scientific papers, contributed to several books and has done extensive scientific and public presentations. Professor Alemseged undertakes cutting edge field and laboratory research in the field of human evolution and paleoanthropology. To achieve these goals, he conduct multidisciplinary paleoanthropological field work in some of the hominin fossil hotspots in Africa while also applying novel imaging and visualization methods to analyze and interpret fossils of early human ancestors.

The main theme of his research revolves around elucidating the milestone events that shaped the course of human evolution after the human lineage separated from the chimpanzee lineage around 7 million years ago. Among the top questions he asks and has contributed answer to are: 1 what was the zeresenay alemseged biography, mode and patterns of upright walking at different stages of our evolution; 2 when and where did our lineage start to use and make stone tools to interact with nature and other species; 3 when and how did we acquire childhood, the extended dependence of young individuals on care givers, which makes H.
