Orrorin Tugenensis….They came before 6 million years on earth
and they are by far the most oldest
known member of the human family.
Ardipithecus Ramidus….They were discovered
in December 1992 and probably walked upright. They came before 4.4 million
years ago.
Australopithcus Anamensis....
They came on Earth before 4.2 to 3.9 million years ago.
They possess a mix of advanced and
primitive traits.
Australiopithecus Afarensis...They came on Earth
before 3.6 to 2.9 million years ago and
had a very low forehead with
prominent brow ridge.
Australiopithecus Africanus...They came on Earth
before 3 to 2 million years ago and showed marked differences in size between males
and females.
Australiopithecus AethiopicusThey came on Earth
before 2.7 to 2.3 million years ago and had a peculiar mixture
of primitive and highly derived traits.
Australiopithecus Garhi…They were here on
Earth before 2.5 million years ago and
were the earliest known tool holders.
Australiopithecus Boisei…They came 2.3 to 1.4
million years ago and probably inhabited
mixed woodland and savanna habitats.
Homo Habilis…They came 2.3 to 1.6
million years ago and were called handy
man because of the wealth of tools they
used.
Homo Erectus….They came before 1.8
to 0.3 million years ago. They had large
molars, an unpronounced chin
and a long skull.
Australiopithecus Robustus… They had came 1.8 to 1.5 million years ago
and had flat and concave faces.
Homo Heidelbergensis… They came here
6,00,000 to 1,00,000 years ago and their
skulls share features with both Erectus and
modern Sapiens.
Homo Neanderthalensis…They came 2,50,000
years to 30,000 years ago on earth and they
had a brain just slightly larger than that of modern humans.
…and the final stage…
Homo Sapiens…They came here 1,00,000 years
ago to present. They have a large brain size, a forehead that
rises sharply, very small eyebrow ridges, a prominent chin and
lighter bone structure. They also included for making clothing, engravings a sculptures and a
fine artwork.
