A. afarensis is now a widely accepted species, and it is now generally thought that Homo and Paranthropus are sister taxa deriving from Australopithecus, but the classification of Australopithecus species is in disarray. Australopithecus is considered a grade taxon whose members are united by their similar physiology rather than close relations ...

Lucy’s discovery transformed our understanding of human origins. Don Johanson, who unearthed the Australopithecus afarensis remains in 1974, recalls the moment he found the iconic fossil.
The genera Homo (which includes modern humans), Paranthropus, and Kenyanthropus evolved from some Australopithecus species. Australopithecus is a member of the subtribe Australopithecina, [4] [5] which sometimes also includes Ardipithecus, [6] though the term "australopithecine" is sometimes used to refer only to members of Australopithecus.
The femur (thigh bone), tibia (shin bone), and 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 afarensis, are long and curved. This suggests that while ...
Determining which species of australopithecine (if any) is ancestral to the genus Homo is a question that is a top priority for many paleoanthropologists, but one that will likely elude any conclusive answers for years to come. Nearly every possible species has been suggested as a likely candidate, but none are overwhelmingly convincing.
AL 200-1 (Afar Locality) is the fossilized upper palate and teeth of the species Australopithecus afarensis, estimated to be 3.0-3.2 million years old. [1] Its characteristics are an ape-like arrangement of teeth including spatulate incisors and a gap between the canines and outside incisors.
Homo (from Latin homō 'human') is a genus of great ape (family Hominidae) that emerged from the genus Australopithecus and encompasses only a single extant species, Homo sapiens (modern humans), along with a number of extinct species (collectively called archaic humans) classified as either ancestral or closely related to modern humans; these include Homo erectus and Homo neanderthalensis.
