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.
Marie Eugene Francois Dubois Part of a skull 1887 1891 Sumatra
Homo Erectus Marie Eugene Francois Dubois 1892 ThighBone
Raymond Dart 1924 Taung Child
Davidson Black Ralph Von Koenigswalt Francis Clark Howell 1950 1960 • 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.
