What does studying Selam show about Australopithecus afarensis?
For the first time, scientists have thoroughly examined the two complete shoulder blades of the fossil “Selam.” Analyses of these rare bones showed them to be quite apelike, suggesting that this species was adapted to climbing trees in addition to walking bipedally when on the ground.
Who is the person discovered Selam?
Zeresenay (Zeray) Alemseged
The fossil, known as “Selam,” is a nearly complete skeleton of a 2.5-year-old child discovered in Dikika, Ethiopia in 2000 by Zeresenay (Zeray) Alemseged, professor of organismal biology and anatomy at the University of Chicago and senior author of the new study.
Did Lucy the ape have a child?
But unlike Lucy, who was well into adulthood by the time she died, the recently discovered fossil is that of an infant, one who lived 3.3 million years ago (and yet has nonetheless been dubbed “Lucy’s baby”).
How old was Selam when’s he died?
3 million-year-
The 3 million-year-old spine of Selam, an Australopithecus afarensis who died at the age of 2 or 3 in what is now Ethiopia. This is the oldest-complete cervical and thoracic spine from a human ancestor. The image in the upper left shows the spine as it was preserved in sandstone.
Did Australopithecines climb trees?
The scans of Lucy’s arm bones showed they were heavily built, like chimpanzees, indicating that members of this species spent significant time climbing in trees and used their arms to pull themselves up in the branches. Australopithecus afarensis possessed a combination of ape-like and human-like traits.

Who found Turkana Boy?
Kamoya Kimeu
This specimen is the most complete early hominin skeleton ever found. It was discovered in 1984 by Kamoya Kimeu on the bank of the Nariokotome River near Lake Turkana in Kenya. Estimates of the individual’s age at death range from 7 to 11 years old.
How did Dr Zeray alemseged age the fossil he found?
In 2010, an international team of scientists led by Alemseged discovered evidence in the Afar region of Ethiopia that Australopithecus afarensis was using stone tools and eating meat roughly 3.4 million years ago, pushing the timeframe of human tool use and manufacture back by nearly a million years.
How old is the skull of the Australopithecus afarensis?
Here we describe a well-preserved 3.3-million-year-old juvenile partial skeleton of Australopithecus afarensis discovered in the Dikika research area of Ethiopia. The skull of the approximately three-year-old presumed female shows that most features diagnostic of the species are evident even at this early stage of development.
Where was the skull of the Selam found?
Selam (DIK-1/1) is the fossilized skull and other skeletal remains of a three-year-old Australopithecus afarensis female hominin, whose bones were first found in Dikika, Ethiopia in 2000 and recovered over the following years.
How old is Lucy the baby Australopithecus?
Although she has often been nicknamed Lucy’s baby, the specimen has been dated at 3.3 million years ago, approximately 120,000 years older than ” Lucy ” (dated to about 3.18 mya). The fossils were discovered by Zeresenay Alemseged, and are remarkable for both their age and condition.
What kind of brain did Selam The Ape have?
Selam’s brain case also suggests that while her intellect was more similar to a chimp’s than a person’s, her species’s brain had already started to evolve in the direction that would produce modern human intelligence.
