  • With music and smooth motion between pictures
  • Until very recently, scientists believed that this was the path of our evolution, i.e starting with Lucy. However, this was proved wrong.Briefly discuss the two timelines of the book and how did the author trace both.How did we come to that stage?Timeline of the human evolution and the fossil records
  • Scientists findings from 1887-2002 over 7 million years. It all starts in 1856, when they found bones of the Homo neanderthalensis and they gave it to Karl Fuhlrott
  • In 1924, Raymond Dart found a full skull of a child in the Kalahari Desert.He found that it was earlier than the Java Man finding as it is more Ape-like. Similarly, other scientists refused to believe in him, because not only did he propose the creation of a new family to incorporate the "man-Apes“, he went as far as to say that Apes aroused in Africa, when it was believed that they did in Asia. They believed that the skull was that of an Ape, and not a transition to humans. At that time, there were 4 agreed upon categories of ancient hominid.
  • On the other hand, in 1974, Lucy was discovered in Ethiopia by Donald Johanson. She had made the headlines for long, suggesting she was our ancestor.However, her skeleton was not complete, making scientists doubt that she could be on the linear path to our human evolution. Her hands were missing, as well as her feet, which could’ve made the link possible if they were present. Her pelvis bones on the other hand, falsified the theory, showing that she couldn’t walk much.Two years later, in 1976,they discovered footprints left by 2 individuals of the same family as Lucy.This finding was important because it showed how from little evidence, scientists can assume a lot of details that are enough to distort realities.
  • Much later on, in 2001, a team lead by Meave Leaky found 4 new specimens of Lucy's age that proved that she was an unsuccessful side branch, because they showed no indication of evolution.In the same year, her team discovered the oldest Hominids yet found (5.2-5.8 Million years) In 2002, they found an older Hominid (7 million years) that was not human like but more of an Ape

  • Human Ancestry
    “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
    • Tracing by the chronological order of the different species
    • Through the dates of the findings that added to the fossil record.
  • Homo neanderthalensis
    1856
  • Marie Eugene Francois Dubois

  • Homectus

  • Davidson Black

    Homo 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.
  • Ralph Von Koenigswalt

    Solo river
    JAVA
  • Francis Clark Howell
    1960
    Australopithecus
    Homo
  • Homo Habilis
    1960
  • This 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.
  • Donald Johanson
