Earth formed over 4.5 billion years ago with its initial condition
greatly affected by the trauma of giant impacts. In this lecture,
Professor David Stevenson discusses how this trauma affects the
similarities and differences between Earth and Moon, the core, possible
initial layering of the mantle and the conditions for the early
evolution, including timing for the origin of life.
This lecture was presented by The Research School of Earth Sciences, ANU College of Science.
