Keeping this in consideration, what species are gracile Australopithecus?
The gracile australopithecines (members of the genus Australopithecus) (Latin australis "of the south", Greek pithekos "ape") are a group of extinct hominids that are closely related to humans.

Also Know, is Australopithecus a genus or a species? The genus Australopithecus is a collection of hominin species that span the time period from 4.18 to about 2 million years ago. Australopiths were terrestrial bipedal ape-like animals that had large chewing teeth with thick enamel caps, but whose brains were only very slightly larger than those of great apes.
Similarly, when referring to gracile australopithecines gracile refers to what?
In the case of australopiths, “gracile†and “robust†refer to the relative size of the jaws, teeth and chewing muscles (all contributing to the “masticatory apparatusâ€). Traditionally, graciles include the ≥2 million year old Australopithecus afarensis and africanus, and robusts include the later A.
What genus likely evolved from Australopithecus?
The genera Homo (which includes modern humans), Paranthropus, and Kenyanthropus evolved from Australopithecus. Australopithecus is a member of the subtribe Australopithecina, which also includes Ardipithecus, though the term "australopithecine" is sometimes used to refer only to members of Australopithecus.
Related Question Answers
How do gracile and robust australopithecines differ?
The main difference between gracile and robust is that gracile species had smaller cheek teeth, pronounced prognathism, less flared cheeks, and no sagittal crest, but robust species had enormous cheek teeth, robust jaws and massive jaw muscles, sometimes anchored to a bony crest running along the top of the skull.What derived features are found in gracile australopithecines?
They are characterized by several features of the skull that give them a "robust" appearance when compared to other, more gracile hominins. The most notable of these features are large, thickly enameled, postcanine teeth that were supported by deep and broad mandibular corpora with tall and broad rami (Fig.Who named the species Australopithecus?
History of Discovery:After Prof. Raymond Dart described it and named the species Australopithecus africanus (meaning southern ape of Africa), it took more than 20 years for the scientific community to widely accept Australopithecus as a member of the human family tree.
Which of these species of Australopithecines are referred to as robust?
Paranthropus robustus is an example of a robust australopithecine; they had very large megadont cheek teeth with thick enamel and focused their chewing in the back of the jaw. It is now known that 'robust' refers solely to tooth and face size, not to the body size of P.What are the four pre Australopithecus species?
