The students from the third form (aged 14-15) studied the evolutions of the human body since the first Hominids. They made some research about oldest ancestors: the Toumaï  Man or Sahelanthropus tchadensis  and tried to find out if this skull belonged to the human lineage or to the lineage of chimpanzees.

For that purpose, they studied the physical characteristics, and noticed that the shape of the skull, the shape of the arch of the eyebrow, as well as the face looked much more like the characteristics of the skulls of chimpanzees.

Only the teeth really looked like the human characteristics.

However, after studying the tree of evolution, today clearly established by the scientists, the students noticed that the skull of the Toumaï Man was placed by the scientists in the human lineage, and it was even the oldest representative known to this day!

They deduced that it is not only the shared number of characteristics that must be taken into account to find out whether a skeleton belongs to one lineage or another, but also which character is shared: teeth are an essential evolution sign!

The pupils then studied the other species of human beings which followed up to our present species: Homo Sapiens. They studied the physical characteristics, as well as the possible cohabitations between the various human species.
