Perhaps the most widely used evidence for the theory of evolution through natural selection is the fossil record.

However, your readout from your radioactivity measuring instrument says you have only 25% Carbon-14 and 75% Nitrogen-14, so your fossil must have been through more than one half-life.Simulation of many identical atoms undergoing radioactive decay, starting with either 4 atoms per box (left) or 400 (right).The number at the top is how many half-lives have elapsed.The term is commonly used in nuclear physics to describe how quickly unstable atoms undergo, or how long stable atoms survive, radioactive decay.The term is also used more generally to characterize any type of exponential or non-exponential decay.
