This year marks the 200th anniversary of Charles Darwin’s birth and the 150th anniversary of On the Origin of Species. This work introduced the theory that species evolve over the course of generations through a process of natural selection which favours certain traits over others to give an organism a better chance of surviving long enough to reproduce. Over the past 150 years, evidence accumulated from palaeontology, evolutionary biology, microbial genetics, molecular genetics, embryology, anatomy and other scientific disciplines has systematically corroborated the theory of evolution.
Evidence of evolution has even come from an unexpected quarter: nuclear physics. Claudio Tuniz from UNESCO’s Abdus Salam International Centre for Theoretical Physics explains in the latest issue of UNESCO’s journal, A World of Science, how new chronometers and x-ray microscopes developed through research in basic physics are helping to trace human evolution and dispersal over the past two million years.
