“The Mysterious Biped”

How did this Modern Man come

to life? How did we get to what we are today as humans living in such

diverse places?

In his book A Short History of Nearly Everything,

The Two timelines of Bill Bryson

The first is traced by the chronological order of the different species

The other one is through the dates of the findings that added to the fossil record.

Tracing through the dates of the findings

that added to the fossil record.

Homo neanderthalensis

Part of a skull

18871891

Homo Erectus

1892

Thigh Bone

Raymond Dart

Taung Child

1924

Robert Broom

Davidson Black

Peking manHomo Erectus

Other researchers looked for more bones in that area, but the findings were lost in an attack in 1941 during the Second World War.

The continuous search for more fossils did not stop, and by the 1950’s, the number of the known categories grew to be over 100.

1950

JAVA

Ralph Von Koenigswalt

Solo river

But of course, with the number of findings increasing, the record

needed organization.

Francis Clark Howell

19601. Australopithecus 2. Homo

Homo Habilis

1960This decade also gave rise to many other

species, and before we know it, it was chaos again as no central authority

decides on names of species.
