What were some physical traits of Australopithecus afarensis?
afarensis had both ape and human characteristics: members of this species had apelike face proportions (a flat nose, a strongly projecting lower jaw) and braincase (with a small brain, usually less than 500 cubic centimeters — about 1/3 the size of a modern human brain), and long, strong arms with curved fingers …
How did Australopithecus look like?
Fossils show this species was bipedal (able to walk on two legs) but still retained many ape-like features including adaptations for tree climbing, a small brain, and a long jaw. many cranial features were quite ape-like, including a low, sloping forehead, a projecting face, and prominent brow ridges above the eyes.

Did a afarensis have a divergent big toe?
Their feet, mostly, told the tale: the divergent, opposable big toe, long digits and other bones of the newfound species did not match the feet of afarensis.
Why Australopithecus is described as a man with ape brain?
Australopithecus can be considered as a connecting link between ape and man due to the following ape-like and man-like characteristics shown by it : the jaws and teeth were large than those of modern man.
Did africanus or afarensis come first?
africanus was more derived than Au. afarensis. This is not surprising considering that they lived at least one million years later, as well as the trend within the hominin lineage to become more encephalized and manually dexterous over time.
Is a afarensis gracile?
Australopithecus afarensis and africanus, and the other species above, are known as gracile australopithecines, because of their relatively lighter build, especially in the skull and teeth. (Gracile means “slender”, and in paleoanthropology is used as an antonym to “robust”.)
What was the cranial capacity of Au. afarensis?
about 375 to 550 cc
Australopithecus afarensis Afarensis had an apelike face with a low forehead, a bony ridge over the eyes, a flat nose, and no chin. They had protruding jaws with large back teeth. Cranial capacity varied from about 375 to 550 cc. The skull is similar to that of a chimpanzee, except for the more humanlike teeth.

What are the facial features of the German people?
There ARE in fact distinctive German facial features. It’s just that they aren’t very well defined because of peoples’ mobility, especially in the modern era. But centuries of less mobility up until now have created a certain look or regional looks that can still be seen today. However, it’s not just one german cookie-cutter look.
What is the difference between Au afarensis and modern humans?
Similar to chimpanzees, Au. afarensis children grew rapidly after birth and reached adulthood earlier than modern humans. This meant Au. afarensis had a shorter period of growing up than modern humans have today, leaving them less time for parental guidance and socialization during childhood.
