The figure shows that the number of different cell types in organisms has been increasing over time, starting from a common origin point around 700 million years ago. Based on this trend, we can predict that organisms with around 100 different cell types would have originated around 500 million years ago, which corresponds to the time period of the Cambrian explosion when there was a rapid diversification of animal life with complex body plans.
