EVOLUTION UNDER WAY  ~4 million years

Australopithecus anamensis is a fossil species of Australopithecus. He is thought to have lived from 4.1 and 3.9 million years ago. The older specimens were found between two layers of volcanic ash, dated to 4.17 and 4.12 million years, coincidentally when A. afarensis appears in the fossil record.

Australopithecus afarensis is an extinct hominid which lived between 3.9 and 2.9 million years ago. A. afarensis was slenderly built, like the younger Australopithecus africanus. It is thought that A. afarensis was ancestral to both the genus Australopithecus and the genus Homo, which includes the modern human species, Homo sapiens. The most famous fossil is the partial skeleton named Lucy by Donald Johanson and colleagues, after they played the Beatles song Lucy in the Sky with Diamonds over and over in celebration of their find.

演化繼續進行中 ~4百萬年前

湖畔南方古猿是南方古猿的化石種。牠被認為存活於41十萬年到39十萬年前。較為早期的樣本在兩個火山灰層當中發現,約在417萬年到412萬年前,同時湖畔南方古猿正出現在此時的化石紀錄中。

阿法南方古猿是一種已滅絕的原人,存活於39十萬年到29十萬年前。牠的體態修長,如同較年輕的非洲南方古猿。牠也被認為是南方古猿屬與人屬的祖先,後者包含了現代人類及智人。最為出名的不完整骨骼化石由唐納德.喬納森及其同事命名為露西,他們為了慶祝其發現,演奏了披頭四的歌露西在鑽石天空裡一遍又一遍。
