Stages of Evolution

Really interesting…..

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.
