How do you study tiny 200-million-year-old fossilised dinosaur embryo bones, at a resolution of .006 millimetres? Scan them in a synchrotron under high-energy X-rays generated by a kilometre-wide ring of electrons travelling at .99% of the speed of light.
Two prominent South African scientists explain why the Karoo region provides not only a historical record of biological change over a period of Earth's history but also a means to test theories of evolutionary processes over long stretches of time.
