COLLOQUIUM: Estimating the Age of Life Using Moore's Law
Moore's law is an empirical observation that the complexity of computer chips measured by the number of transistors doubles every 18-24 months. Because there is similarity between the evolution of human technology and living organisms, it is intriguing if an exponential increase in complexity can be found in the evolution of living organisms. Functional complexity of organisms can be roughly approximated by the size of non-redundant functional genome. It appears that genome complexity indeed increased nearly exponentially and doubled in size every 340 million years.
