Until then, Lucy, from the Australopithecus afarensis branch at 3.5 million years ago, was the reference.

Discovered in Ethiopia, it was nevertheless known to have South African cousins.

On the site of Sterkfontein, northwest of Johannesburg, several hundred Australopithecine fossils belonging to the Australopithecus africanus branch, among which a certain "

 Madame Ples

 " discovered in 1947 had been dated between 2.1 and 2.6 million AD. years. 

Several paleontologists, including the French researcher Laurent Bruxelles, have nevertheless noted several inconsistencies.

Starting with the chronology: their analysis reveals on the one hand an abnormal time difference with an Australopithecus,

Little Foot

, even older than "

 Madame Ples

 " found in the same area.

On the other hand, at the same time, Homo habilis, the first representative of the human race, was in the region, which seemed "weird" for the French geologist.

A continent-wide cradle of humanity

 To overcome these inconsistencies

, the researchers therefore employed another dating method by replacing that of carbon 14

 . contemporary with Lucy.

If this hypothesis is not to the taste of all researchers, it comes, in any case, to question the location of the “cradle of humanity”: Southern Africa or South Africa?

French researcher Laurent Bruxelles pleads for a pan-African vision of evolution.
