How Physics Can Measure Tempo and Mode of Human Evolution
March 29, 2021 
8 am EDT (3 pm EET – SESAME, Jordan time)


The lecture will be delivered by Claudio Tuniz (Abdus Salam International Centre for Theoretical Physics in Trieste, Italy). The whole duration will be about 60 mn.

The reconstruction of human history in the deep past is based on data obtained through the characterisation of hominid fossils, of their cultural products, and of the environment in which they lived. Such data include age and microstructure of the materials of interest. Dating methods based on radioactivity, such as radiocarbon, luminescence, and uranium-thorium, provide reliable chronologies for the periods relevant to human evolution. New X-ray and neutron microscopes allow us to reconstruct the internal microstructure of bones and teeth and to perform ‘virtual’ histological analyses. Ions, lasers, and synchrotron radiation microprobes can provide elemental and isotopic maps of tooth enamel to study diet and biologic development. A brief review of the most recent dating and micro-analytical methods, with some examples of their application in human origin studies, will be presented.
