Evolution Details[edit | edit source]

Australopithecus Afarensis is the Fourth Evolution Leap in the game. This evolution is played from approximately 3,800,000 years ago and will change to the next species after you reach approximately 2,500,000 years ago.

Trivia[edit | edit source]

Australopithecus afarensis is one of the longest-lived and best-known early human species—paleoanthropologists have uncovered remains from more than 300 individuals! Found between 3.85 and 2.95 million years ago in Eastern Africa (Ethiopia, Kenya, Tanzania), this species survived for more than 900,000 years, which is over four times as long as our own species has been around.  It is best known from the sites of Hadar, Ethiopia (‘Lucy’, AL 288-1 and the 'First Family', AL 333); Dikika, Ethiopia (Dikika ‘child’ skeleton); and Laetoli (fossils of this species plus the oldest documented bipedal footprint trails). Au. afarensis had many human-like and characteristics: members of this species had apelike face proportions (a flat nose, a strongly projecting lower jaw) long, strong arms with curved fingers adapted for climbing trees. They also had small canine teeth like all other early humans, and a body that stood on two legs and regularly walked upright. A. Afarensis and other australopithecines were probably vulnerable to predation, Their adaptations for living both in the trees and on the ground helped them survive for almost a million years as climate and environments changed.[1]

Australopithecus afarensis is an extinct species of australopithecine which lived from about 3.9–2.9 million years ago million years ago in the Pliocene of East Africa. The first fossils were discovered in the 1930s, but major fossil finds would not take place until the 1970s. unearthed in 1974, specimens in Hadar, Ethiopia, the most significant being the exceedingly well-preserved skeleton AL 288-1 ("Lucy") and the site AL 333 ("the First Family"). Beginning in 1974, Mary Leakey led an expedition into Laetoli, Tanzania, and notably recovered fossil trackways. In 1978, the species was first described, but this was followed by arguments for splitting the wealth of specimens into different species given the wide range of variation which had been attributed to sexual dimorphism (normal differences between males and females). A. afarensis most likely descended from A. anamensis and may have possibly gave rise to Homo, though the latter hypothesis is not without dissent.[2]
